[0017] The present embodiment will be described below with reference to the drawings. The embodiments are not limited to the following embodiments. Furthermore, the content described in one embodiment is generally applicable to other embodiments as well. Furthermore, the embodiments and modifications can be combined as appropriate.

[0018] (Electricity and hydrogen supply system 1) The electric power and hydrogen supply system 1 of the first embodiment includes a first electric power and hydrogen supply station 10a, a second electric power and hydrogen supply station 10b, a third electric power and hydrogen supply station 10c, a server 100, electric vehicles (first electric vehicle c1 to fourth electric vehicle c4), power sources to be tested (first power source to be tested G1, second power source to be tested G2), load testing devices (rechargeable load testing device LB1, electrolytic load testing device LB2), and load testing mobile devices (first load testing mobile device t1, second load testing mobile device t2) (see Figures 1 to 3).

[0019] (First power / hydrogen supply station 10a to third power / hydrogen supply station 10c) Each of the first power / hydrogen supply station 10a to the third power / hydrogen supply station 10c has a first power generation device 11, a second power generation device 12, a control device 13, a charger 14, a station side display unit 15, a station side operation unit 16, a fixed power storage unit 17, a portable power storage unit 18, loads (first load 19a, second load 19b, third load 19c, fourth load 19d), and a hydrogen storage unit 21 (see Figure 4).

[0020] (First power generating unit 11) The first power generating device 11 is a power generating device (renewable energy-derived power generating device) that generates power based on natural energy (renewable energy), such as a solar power generating device or a wind power generating device. The first power generating device 11 is always in a state where it can generate power. However, if the first power generating device 11 is a wind power generating device and the wind force received by the first power generating device 11 exceeds a predetermined wind force, the first power generating device 11 is put into a state in which it cannot generate power. The first power generating unit 11 is installed on the roof of a building (casing) 25 or the like. The electric power obtained by the first power generation device 11 is supplied via the control device 13 to the charger 14, the fixed power storage unit 17, the portable power storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, etc.

[0021] (Second power generating unit 12) The second power generator 12 is a power generator (fuel cell) that generates electricity based on hydrogen. The second power generating device 12 is set to a state in which it can generate power when, for example, the power supplied from the first power generating device 11 is insufficient. The second power generation device 12 is installed inside the building 25 or on the roof of the building 25, for example. The electric power obtained by the second power generating device 12 is supplied via the control device 13 to loads (first load 19a to fourth load 19d) and the like. That is, normally, the electric power obtained by the second power generation device 12 is not supplied to the hydrogen storage unit 21. However, when a load test of the second power generation device 12, which will be described later, is performed, the electric power obtained by the second power generation device 12 is also supplied to the hydrogen generation device 21b of the hydrogen storage unit 21 and the like. Furthermore, water discharged from the second power generating device 12 during power generation may be supplied to an electrolyte supply unit 21a, as shown in a fourth embodiment described later.

[0022] (Control device 13) The control device 13 includes a power conditioner, a distribution board, and the like, and performs switching control of the power supply source and switching control of the power supply destination. Specifically, the control device 13 is connected to the first power generation device 11, the second power generation device 12, the fixed power storage unit 17, and the portable power storage unit 18 on the input side. The control device 13 may be further connected to a power receiving device (not shown) of a commercial power supply on the input side. On the output side, the control device 13 is connected to the charger 14, station side display unit 15, fixed power storage unit 17, portable power storage unit 18, loads (first load 19a, second load 19b, third load 19c, fourth load 19d), hydrogen storage unit 21 (hydrogen generation device 21b, heat retention / cooling unit 21c, detection device 21f, hydrogen supply unit 21g), and communication unit 23. However, the first power generator 11 may be directly connected to the portable power storage unit 18, the hydrogen generator 21b, and the like without going through the control device 13. The control device 13 is installed inside a building 25 or the like.

[0023] (Input switching control) If the power P supplied from the first power generation device 11 is less than the power threshold Thp, and the state of charge R1 of the fixed storage unit 17 is lower than the first storage rate threshold Thr1, and / or the storage rate R2 of the portable storage unit 18 is lower than the second storage rate threshold Thr2, the control device 13 determines that the power supplied from the first power generation device 11 etc. is insufficient, and connects to the second power generation device 12 to receive power from the second power generation device 12. In this case, the second power generating device 12 receives a supply of hydrogen from the hydrogen tank 21d of the hydrogen storage unit 21 and generates electric power. In this case, the hydrogen generator 21b is stopped. In this case, the control device 13 may maintain the connection with the first power generation device 11 or may cut off the connection with the first power generation device 11.

[0024] The charging rate R2 of portable power storage unit 18 refers to the charging rate R2 of any of portable power storage devices 18b attached to holding unit 18a of portable power storage unit 18 that has the lowest value.

[0025] However, when the hydrogen filling rate R3 of the hydrogen storage unit 21 is lower than the first hydrogen filling rate threshold Thr3, the second power generation device 12 does not supply power to the control device 13. In this case, the control device 13 receives power supply from the fixed power storage unit 17 or the portable power storage unit 18. The hydrogen filling rate R3 of the hydrogen storage unit 21 is the highest hydrogen filling rate R3 of any of the hydrogen tanks 21d attached to the heat-retaining / cooling unit 21c of the hydrogen storage unit 21. The hydrogen filling rate R3 is defined as the ratio of the amount of hydrogen (cc / g or wt%) stored in the hydrogen tank 21d (absorbed by the hydrogen storage alloy) to the maximum amount of hydrogen that can be stored in the hydrogen tank 21d. The hydrogen filling rate R3 is calculated based on the expansion rate of the hydrogen storage alloy detected by a detector 21f such as a strain sensor attached to the hydrogen storage alloy of the hydrogen tank 21d. Furthermore, hydrogen filling rate R3 may be calculated based on the amount of hydrogen flowing into and discharging from hydrogen tank 21d, as detected by detection device 21f, such as a flow rate sensor, provided in communicating pipe 21e. Communicating pipe 21e communicates with second power generator 12, hydrogen generation device 21b, hydrogen tank 21d, and hydrogen supply unit 21g.

[0026] (Power supply device usage priority (1)) In the first embodiment, power from the first power generation device 11 is given first priority, power from the fixed power storage unit 17 is given second priority, power from the portable power storage unit 18 is given third priority, and power from the second power generation device 12 is given fourth priority, and is supplied to the first load 19a to the fourth load 19d, etc.

[0027] In this case, power from the first power generation device 11 is supplied via the control device 13 to the station side display unit 15, the fixed storage unit 17, the portable storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the communication unit 23. When the power P supplied from the first power generating device 11 is less than the power threshold value Thp, the power from the fixed power storage unit 17 is supplied to the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 via the control device 13. However, power is not supplied from the fixed power storage unit 17 to the portable power storage unit 18 and the hydrogen storage unit 21. When the charging rate R1 of fixed power storage unit 17 is lower than first charging rate threshold Thr1, power from portable power storage unit 18 is supplied to station side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23 via control device 13. However, power supply from portable power storage unit 18 to fixed power storage unit 17 and hydrogen storage unit 21 is not performed. When the charging rate R2 of the portable power storage unit 18 is lower than the second charging rate threshold Thr2, power from the second power generation device 12 is supplied to the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 via the control device 13. However, power is not supplied from the second power generation device 12 to the fixed power storage unit 17, the portable power storage unit 18, and the hydrogen storage unit 21.

[0028] (Power supply device usage priority (2)) However, the use priority order of the power supply devices (first power generation device 11, second power generation device 12, fixed power storage unit 17, portable power storage unit 18) is not limited to the use priority order (1) described above. For example, power may be supplied to the first load 19a to the fourth load 19d in such a manner that power from the first power generation device 11 has first priority, power from the second power generation device 12 has second priority, power from the fixed power storage unit 17 has third priority, and power from the portable power storage unit 18 has fourth priority.

[0029] In this case, power from the first power generation device 11 is supplied via the control device 13 to the station side display unit 15, the fixed storage unit 17, the portable storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the communication unit 23. When the power P supplied from the first power generating device 11 is less than the power threshold value Thp, the power from the second power generating device 12 is supplied to the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 via the control device 13. However, power is not supplied from the second power generating device 12 to the fixed power storage unit 17, the portable power storage unit 18, and the hydrogen storage unit 21. When hydrogen filling rate R3 of hydrogen storage unit 21 is lower than first hydrogen filling rate threshold Thr3, power from fixed power storage unit 17 is supplied to station side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23 via control device 13. However, power is not supplied from fixed power storage unit 17 to portable power storage unit 18 and hydrogen storage unit 21. When the charging rate R1 of fixed power storage unit 17 is lower than first charging rate threshold Thr1, power from portable power storage unit 18 is supplied to station side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23 via control device 13. However, power supply from portable power storage unit 18 to fixed power storage unit 17 and hydrogen storage unit 21 is not performed.

[0030] (Power supply device usage priority (3)) Furthermore, for example, power may be supplied to the first load 19a to the fourth load 19d in such a manner that power from the first power generation device 11 has first priority, power from the fixed power storage unit 17 has second priority, power from the second power generation device 12 has third priority, and power from the portable power storage unit 18 has fourth priority.

[0031] In this case, power from the first power generation device 11 is supplied via the control device 13 to the station side display unit 15, the fixed storage unit 17, the portable storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the communication unit 23. When the power P supplied from the first power generating device 11 is less than the power threshold value Thp, the power from the fixed power storage unit 17 is supplied to the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 via the control device 13. However, power is not supplied from the fixed power storage unit 17 to the portable power storage unit 18 and the hydrogen storage unit 21. When the charging rate R1 of the fixed power storage unit 17 is lower than the first charging rate threshold Thr1, power from the second power generation device 12 is supplied to the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 via the control device 13. However, power is not supplied from the second power generation device 12 to the fixed power storage unit 17, the portable power storage unit 18, and the hydrogen storage unit 21. When hydrogen filling rate R3 of hydrogen storage unit 21 is lower than first hydrogen filling rate threshold Thr3, power from portable power storage unit 18 is supplied via control device 13 to station side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23. However, power is not supplied from portable power storage unit 18 to fixed power storage unit 17 and hydrogen storage unit 21.

[0032] That is, the control device 13 adjusts the power supplied from the first power generation device 11, the second power generation device 12, and the storage devices (fixed storage unit 17, portable storage unit 18) based on the usage priority order set using the station side operation unit 16, etc.

[0033] However, the control device 13 may determine a usage priority order according to the usage status of the second power generation device 12, the fixed storage unit 17, and the portable storage unit 18, and adjust the power supplied from the first power generation device 11, the second power generation device 12, and the storage devices (fixed storage unit 17, portable storage unit 18) based on the usage priority order determined by the control device 13.

[0034] For example, if the time Ta during which power is supplied from the portable power storage unit 18 during a first time TT1 (e.g., TT1 = 24 hours) from the present time in the past is shorter than the time threshold value Tht, the control device 13 determines the usage priority order so that power is supplied to the first load 19a to the fourth load 19d, etc., with first priority from the first power generation device 11, second priority from the fixed power storage unit 17, third priority from the portable power storage unit 18, and fourth priority from the second power generation device 12.

[0035] Furthermore, for example, if the time Tb during which power is supplied from the fixed power storage unit 17 during the first time TT1 from the present time in the past is longer than the time Tc during which power is supplied from the second power generation device 12, the control device 13 determines the usage priority order so that power is supplied to the first load 19a to the fourth load 19d as follows: power from the first power generation device 11 has first priority, power from the second power generation device 12 has second priority, power from the fixed power storage unit 17 has third priority, and power from the portable power storage unit 18 has fourth priority.

[0036] Furthermore, for example, if the time Tb during which power is supplied from the fixed storage unit 17 during the first time TT1 from the present time in the past is shorter than the time Tc during which power is supplied from the second power generation device 12, the control device 13 determines the usage priority order so that power is supplied to the first load 19a to the fourth load 19d as follows: power from the first power generation device 11 has first priority, power from the fixed storage unit 17 has second priority, power from the second power generation device 12 has third priority, and power from the portable storage unit 18 has fourth priority.

[0037] In any of the above-mentioned usage priority order (1), usage priority order (2), and usage priority order (3), a form has been described in which power is not supplied from the fixed power storage unit 17 to the portable power storage unit 18 and the hydrogen storage unit 21, power is not supplied from the portable power storage unit 18 to the fixed power storage unit 17 and the hydrogen storage unit 21, and power is not supplied from the second power generation device 12 to the fixed power storage unit 17, the portable power storage unit 18, and the hydrogen storage unit 21. However, taking into consideration the supply and demand balance of electricity, hydrogen, portable power storage device 18b, and hydrogen tank 21d supplied to first electric vehicle c1, at least one of the following may be performed: power supply from fixed power storage unit 17 to portable power storage unit 18 and hydrogen storage unit 21; power supply from portable power storage unit 18 to fixed power storage unit 17 and hydrogen storage unit 21; and power supply from second power generation device 12 to fixed power storage unit 17, portable power storage unit 18, and hydrogen storage unit 21.

[0038] (Output switching control) The control device 13 is connected to the fixed power storage unit 17 . However, when the charging rate R1 of fixed power storage unit 17 is close to a fully charged state and the power P supplied from first power generation device 11 is equal to or greater than power threshold value Thp, power can be sufficiently supplied from first power generation device 11 to the loads (first load 19a to fourth load 19d), portable power storage unit 18, and hydrogen storage unit 21 without using the power stored in fixed power storage unit 17. Therefore, in such a case, control device 13 cuts off the connection with fixed power storage unit 17.

[0039] Portable power storage unit 18 and control device 13 are always connected to each other. However, when the charging rates R2 of all portable power storage devices 18b attached to holding unit 18a of portable power storage unit 18 are close to the fully charged state, control device 13 cuts off the connection with portable power storage unit 18. In this case, the control device 13 displays a first replacement guide on the station-side display unit 15 to indicate that the charged portable power storage device 18b should be removed from the holding unit 18a and that the incompletely charged portable power storage device 18b should be attached to the holding unit 18a, or displays the first replacement guide on the mobile terminal of the user of the first electricity / hydrogen supply station 10a via the communication unit 23. After the portable power storage device 18b has been replaced, the control device 13 connects it to the portable power storage unit 18.

[0040] The control device 13 is connected to one of the loads (first load 19a, second load 19b, third load 19c, and fourth load 19d) that has been turned on by a user or the like.

[0041] The hydrogen storage unit 21 and the control device 13 are always connected to each other. However, if the hydrogen filling rate R3 of all hydrogen tanks 21d attached to the heat insulation and cooling section 21c of the hydrogen storage section 21 is higher than the second hydrogen filling rate threshold Thr4 (Thr4>Thr3), the control device 13 determines that the hydrogen tanks 21d are sufficiently filled with hydrogen and cuts off the connection to the hydrogen storage section 21. In this case, the control device 13 displays a second replacement guide on the station display unit 15, instructing the user of the first power / hydrogen supply station 10a to remove the hydrogen-filled hydrogen tank 21d from the heat retention / cooling unit 21c and attach the hydrogen tank 21d that has not yet been filled with hydrogen to the heat retention / cooling unit 21c, or displays the second replacement guide on the mobile terminal of the user of the first power / hydrogen supply station 10a via the communication unit 23. After the hydrogen tank 21d has been replaced, the control device 13 connects it to the hydrogen storage unit 21.

[0042] The control device 13 is connected to the communication unit 23 .

[0043] (AC to DC conversion) In the first embodiment, the power passing through the control device 13 is described as AC. For this reason, a device (not shown) for converting power from DC to AC is provided between the control device 13 and one of the first power generating device 11 and the second power generating device 12 that generates DC power. Between fixed power storage unit 17 and control device 13, a device (first conversion device 13a) is provided that converts power from AC to DC and converts power into a predetermined current and voltage. Between portable power storage unit 18 and control device 13, a device (second conversion device 13b) is provided that converts power from AC to DC and converts power to a predetermined current and voltage. In addition, between the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 that are driven by DC and the control unit 13, a device (not shown) is provided that converts power from AC to DC or to a predetermined current and voltage. Between the hydrogen generation device 21b and the control device 13, there is provided a device (not shown) that converts power from AC to DC and converts it into a predetermined current and voltage.

[0044] However, the power passing through the control device 13 may be direct current. In this case, a device for converting AC power to DC power is provided between the control device 13 and one of the first power generating device 11 and the second power generating device 12 that generates AC power. In addition, a device for converting power from DC to AC is provided between the station side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23 that are driven by AC and the control unit 13. In this case, the first conversion device 13a and the second conversion device 13b function as devices for converting into a predetermined current and voltage.

[0045] (Charger 14) Charger 14 is detachably connected to the first electric vehicle c1 and the like, and supplies power from first power generation device 11 and the like to the first electric vehicle c1. Charger 14 may also supply power from the first electric vehicle c1 to fixed power storage unit 17 and the like. In this case, charger 14 has a charging device (first converter 14a) that connects to a charging terminal of the first electric vehicle c1 and charges on-board power storage device 31a of the first electric vehicle c1, and a V2H device (second converter 14b) that connects to a power supply terminal of the first electric vehicle c1 and discharges on-board power storage device 31a of the first electric vehicle c1.

[0046] (Station side display unit 15, station side operation unit 16) The station side display unit 15 displays charging information for the fixed power storage unit 17, charging information for the portable power storage device 18b attached to the holding unit 18a of the portable power storage unit 18, hydrogen filling rate information for the hydrogen tank 21d attached to the heat retention and cooling unit 21c of the hydrogen storage unit 21, information regarding the usage priority of the power supply devices (first power generation device 11, second power generation device 12, fixed power storage unit 17, portable power storage unit 18), reservation information from the first electric vehicle c1, etc. The station side operation unit 16 is used for setting the use priority order and the like.

[0047] The station side display unit 15 and the station side operation unit 16 may be configured as an integrated unit such as a touch panel, or may be configured as separate units. The station-side display unit 15 and the station-side operation unit 16 may be fixed to the building 25 of the first electricity / hydrogen supply station 10a, or may be fixed in a detachable manner. Furthermore, a mobile terminal or the like of the user of the first power / hydrogen supply station 10 a may function as at least one of the station side display unit 15 and the station side operation unit 16 .

[0048] (Fixed power storage unit 17) The fixed power storage unit 17 has a power storage device that stores power from the first power generation device 11 and the like. The power storage device of fixed power storage unit 17 is fixed to a predetermined position inside building 25 without consideration of attachment or detachment.

[0049] When the power supply from first power generation device 11 is insufficient, fixed power storage unit 17 supplies the stored power to loads (first load 19a to fourth load 19d) and the like via control device 13. Furthermore, fixed power storage unit 17 also serves as an auxiliary power source and supplies power to electrical equipment (such as station-side display unit 15) that constitutes first power / hydrogen supply station 10a. However, a power storage device for this auxiliary power source may be provided separately from fixed power storage unit 17.

[0050] The first conversion device 13a and the fixed power storage unit 17 may be used as a rechargeable load test area for performing a load test on a power supply device such as the first power generation device 11. In this case, at least one of first conversion device 13a and fixed power storage unit 17 has a first variable structure for adjusting the load amount when performing an electrolysis load test.

[0051] For example, as the first variable structure, first conversion device 13a has a plurality of AC / DC converters. The plurality of AC / DC converters are connected in parallel and connected to one power storage device of fixed power storage unit 17. When power is supplied from a power source under test (a power supply device such as first power generation device 11) to fixed power storage unit 17 via control device 13, the load amount is adjusted by changing the number of the plurality of AC / DC converters used.

[0052] Furthermore, for example, as the first variable structure, fixed power storage unit 17 has a plurality of power storage devices. The plurality of power storage devices are connected in parallel and connected to one AC / DC converter of first conversion device 13a. The load amount is adjusted by changing the number of the plurality of power storage devices to which power is supplied from the power source under test (a power supply device such as first power generation device 11) via control device 13 and first conversion device 13a.

[0053] Furthermore, for example, as the first variable structure, first conversion device 13a has a plurality of AC / DC converters, and fixed power storage unit 17 has a plurality of power storage devices. The plurality of AC / DC converters are connected in parallel. The plurality of power storage devices are connected in parallel. The plurality of AC / DC converters are respectively connected to the plurality of power storage devices. Therefore, a plurality of sets of AC / DC converters and power storage devices connected in series are provided. The load amount is adjusted by changing the number of the plurality of AC / DC converter and power storage device sets to which power is supplied from the power source under test (power supply device such as first power generation device 11) via control device 13.

[0054] (Portable power storage unit 18) The portable power storage unit 18 includes a holding unit 18a and a portable power storage device 18b. The holder 18a holds the portable power storage device 18b in a detachable manner. The portable power storage device 18b is a power storage device that stores electric power from the first power generation device 11 and the like. The portable power storage device 18b is detachable from the holder 18a and is detachably attached to another electric device such as a second electric vehicle c2 described later to drive the other electric device. When the power supply from the first power generating device 11 is insufficient, the portable power storage device 18b supplies the stored power to the loads (first load 19a to fourth load 19d) and the like via the control device 13.

[0055] Furthermore, the storage of power in the portable power storage device 18b may be performed not only at the first power / hydrogen supply station 10a but also outside the first power / hydrogen supply station 10a. For example, a portable power storage device 18b mounted on the first load test mobile device t1 together with the rechargeable load testing device LB1 may store power supplied from the first test target power source G1 via the rechargeable load testing device LB1 (see Figure 3). The rechargeable load testing device LB1 performs a load test on the first power source G1 under test by charging the portable power storage device 18b with power from the first power source G1 under test. In addition, the portable electricity storage device 18b may be held in the holding section 18a of the second electricity / hydrogen supply station 10b and store electricity supplied from the first power generation device 11 of the second electricity / hydrogen supply station 10b, etc.

[0056] In the first embodiment, an example is shown in which three holding units 18a are provided and three portable power storage devices 18b can be charged simultaneously, but the number of holding units 18a provided is not limited to three.

[0057] The holder 18a of the portable power storage unit 18 is installed inside the building 25 or the like.

[0058] The second conversion device 13b and the portable power storage unit 18 may be used as a rechargeable load test area for carrying out additional tests on the power supply device such as the first power generation device 11. In this case, at least one of second conversion device 13b and portable power storage unit 18 has a second variable structure for adjusting the load amount when performing an electrolysis load test.

[0059] For example, as the second variable structure, portable power storage unit 18 has a plurality of portable power storage devices 18b. The plurality of portable power storage devices 18b are connected in parallel to one AC / DC converter of second conversion device 13b. The load amount is adjusted by changing the number of portable power storage devices 18b that receive power supply from the power source under test (a power supply device such as first power generation device 11) via control device 13 and second conversion device 13b.

[0060] Furthermore, for example, as the second variable structure, second conversion device 13b has a plurality of AC / DC converters, and portable power storage unit 18 has a plurality of portable power storage devices 18b. The plurality of AC / DC converters are connected in parallel. The plurality of portable power storage devices 18b are connected in parallel. The plurality of AC / DC converters are respectively connected to the plurality of portable power storage devices 18b. Therefore, a plurality of sets of AC / DC converters and portable power storage devices 18b connected in series are provided. The load amount is adjusted by changing the number of the sets of AC / DC converters and portable power storage devices 18b to which power is supplied from the power source under test (a power supply device such as first power generation device 11) via control device 13.

[0061] (1st load 19a~4th load 19d) The first to fourth loads 19a to 19d are electrical appliances installed inside or near the building 25, such as light bulbs, elevators, refrigerators, air conditioners, and televisions. Power is supplied via the control device 13 to one of the first to fourth loads 19a to 19d that the user has operated to be turned on. At least one of the first load 19a to the fourth load 19d may be a load testing device that performs a load test on a power supply device such as the first power generating device 11.

[0062] (hydrogen storage unit 21) The hydrogen storage unit 21 has an electrolyte supply unit 21a including a water intake unit 21a1, a hydrogen generator 21b, a heat-retaining / cooling unit 21c, a hydrogen tank 21d, a communication pipe 21e, a detector 21f, and a hydrogen supply unit 21g.

[0063] The electrolyte supply unit 21a supplies the hydrogen generator 21b with an electrolyte such as water for electrolysis.

[0064] The electrolyte is collected at the water intake section 21a1. The water intake section 21a1 is a dehumidifying device that condenses moisture in the air and collects the condensed water as an electrolyte. The dehumidifier is composed of, for example, a cooling plate, a heat dissipation plate, and a thermoelectric element (Peltier element) provided between them. In the first embodiment, the cooling plate is provided inside the building 25 to condense moisture contained in the air inside the building 25. However, the cooling plate may be provided outside the building 25 to condense moisture in the air outside the building 25. It is also possible that a part of the air conditioner in the building 25 functions as the dehumidifier, and water condensed by the operation of the air conditioner is collected as the electrolyte. Furthermore, water intake section 21a1 may be configured to collect rainwater from above building 25, water stored around building 25, or water from a river flowing around the building. The dehumidifier may also be used to extract moisture contained in gases (oxygen, hydrogen) generated by electrolysis in the hydrogen generator 21b.

[0065] The hydrogen generator 21b performs electrolysis based on the electric power supplied from the first power generator 11 and the like to generate hydrogen. The electrolytic solution supply unit 21a and the hydrogen generation device 21b may be configured as separate bodies or may be configured as an integrated body.

[0066] The hydrogen generator 21b may be used as an electrolytic load test area for performing load tests on power supply devices such as the first power generator 11. The load amount in the load test in the electrolytic load test area is adjusted by controlling the supply of electrolyte from the electrolyte supply unit 21a to the hydrogen generation device 21b, controlling the movement of at least one of the electrodes in the hydrogen generation device 21b, and controlling the movement of the insulator between one and the other of the electrodes in the hydrogen generation device 21b. That is, at least one of the electrolytic solution supply unit 21a and the hydrogen generation device 21b has a third variable structure for adjusting the load amount when an electrolysis load test is performed.

[0067] For example, the third variable structure may include at least one of the electrodes (e.g., a plurality of cathodes), and the load amount may be adjusted by changing the number of cathodes through which current from the power supply under test (e.g., the first power generation device 11) flows.

[0068] Furthermore, for example, the third variable structure is configured so that at least one of the electrodes (e.g., cathode 21b1) is movable in the vertical direction. The load amount is adjusted by changing the contact area between at least one of the electrodes that is movable in the vertical direction and the electrolyte (electrode movement control, see FIG. 7). FIG. 7 shows an example in which a container that holds the electrolyte constitutes anode 21b2, cathode 21b1 is provided inside the container, and cathode 21b1 is held by holding mechanism 21b3 in a state where it can be moved in the vertical direction, i.e., in a state where the contact area with the electrolyte is variable.

[0069] Furthermore, for example, the third variable structure is configured to adjust the amount of electrolyte solution supplied to the hydrogen generation device 21b. By changing the amount of electrolyte solution and changing the contact area between the electrodes and the electrolyte solution, the load amount is adjusted (electrolyte solution supply control).

[0070] Furthermore, for example, the third variable structure is provided with an insulator 21b4 configured to be movable between one of the electrodes (e.g., cathode 21b1) and the other of the electrodes (e.g., anode 21b2). The load amount is adjusted by changing the degree of shielding between the electrodes by insulator 21b4 (insulator movement control, see FIG. 8). FIG. 8 shows an example in which cathode 21b1 and anode 21b2 are provided inside a container that holds an electrolyte, insulator 21b4 is provided between cathode 21b1 and anode 21b2, and insulator 21b4 is held by holding mechanism 21b3 in a state in which it can move up and down.

[0071] The third variable structure allows for easier fine adjustment of the load amount compared to the rechargeable load test area, so the rechargeable load test area is used to adjust large load amounts, and the electrolytic load test area is used to adjust small load amounts.

[0072] Heat-retaining / cooling unit 21c detachably holds hydrogen tank 21d and heats or cools held hydrogen tank 21d. Specifically, when hydrogen generated by the hydrogen generation device 21b is to be absorbed, the heat retention / cooling unit 21c cools the hydrogen tank 21d held by the unit 21c itself. When hydrogen is released from the hydrogen tank 21d, the heat retention / cooling unit 21c heats the hydrogen tank 21d that it holds, or stops cooling it. However, as shown in a fourth embodiment described later, the hydrogen tank 21d may be heated using heat obtained by a device separate from the heat retention and cooling unit 21c, such as a solar water heater 20.

[0073] The hydrogen tank 21d has a hydrogen storage alloy that stores hydrogen and a container that holds the hydrogen storage alloy. The container of the hydrogen tank 21d holds the hydrogen storage alloy inside. The hydrogen tank 21d stores hydrogen under high pressure or low temperature and releases the stored hydrogen when the state is no longer under high pressure or low temperature. The hydrogen tank 21d is in communication with the second power generator 12, the hydrogen generator 21b, and the hydrogen supply unit 21g via a communication pipe 21e. Furthermore, moisture (drain water, etc.) contained in gases from the hydrogen generator 21b, the hydrogen tank 21d, the communication pipe 21e, etc. may be supplied to the electrolyte supply unit 21a as shown in a fourth embodiment described later.

[0074] At least one of the hydrogen tank 21d and the communication pipe 21e is provided with a detection device 21f such as a strain sensor or a flow rate sensor. The detector 21f is used to calculate the hydrogen filling level (hydrogen filling rate R3) of the hydrogen tank 21d.

[0075] In the first embodiment, the hydrogen tank 21d is described as being portable, detachable from the heat retention and cooling unit 21c, and capable of being mounted on the fourth electric vehicle c4 and the second load test mobile device t2 (described later). However, at least one of the hydrogen tanks 21d may be fixed to the heat retention and cooling unit 21c or the like without consideration of detachment. In the first embodiment, the hydrogen tank 21d stores hydrogen by absorbing it into a storage alloy. However, the hydrogen tank 21d may store any of an organic hydride containing hydrogen, liquefied hydrogen, and compressed gaseous hydrogen.

[0076] The hydrogen supply unit 21g is detachably connected to the third electric vehicle c3 or the like, and supplies hydrogen from the hydrogen tank 21d or the like to the on-board fixed hydrogen storage device 31c of the third electric vehicle c3. Furthermore, a high-pressure hydrogen tank or the like may be detachably connected to the hydrogen supply unit 21g, in which case hydrogen from the high-pressure hydrogen tank or the like may be supplied to the hydrogen tank 21d or the like.

[0077] Furthermore, the accumulation (storage) of hydrogen in the hydrogen tank 21d may not only be performed at the first power / hydrogen supply station 10a, but also outside the first power / hydrogen supply station 10a. For example, a hydrogen tank 21d mounted on the second load test mobile device t2 together with the electrolytic load testing device LB2 may store hydrogen generated from the second test target power source G2 via the electrolytic load testing device LB2 (see Figure 3). The electrolysis load testing device LB2 performs a load test on the second test target power source G2 by electrolyzing an electrolyte such as water using power from the second test target power source G2 and storing the hydrogen obtained by the electrolysis in the hydrogen tank 21d. In addition, the hydrogen tank 21d may be held in the heat-retaining cooling section 21c of the second power / hydrogen supply station 10b, and may store hydrogen based on the electricity supplied from the first power generation device 11 of the second power / hydrogen supply station 10b, etc.

[0078] (Buffer tank) Buffer tanks 21d1 for temporarily storing hydrogen may be provided in communication pipe 21e between hydrogen generator 21b and hydrogen tank 21d, and between hydrogen tank 21d and hydrogen supply unit 21g.

[0079] (Decompression device) Furthermore, the communication pipe 21e may be provided with a pressure reducing device 21d2 for adjusting the pressure.

[0080] (Communications Department 23) The communication unit 23 transmits to the server 100 location information of the first power / hydrogen supply station 10a including the communication unit 23, business information, charging information of the portable power storage device 18b attached to the holding unit 18a of the portable power storage unit 18, hydrogen filling rate information of the hydrogen tank 21d attached to the heat retention / cooling unit 21c of the hydrogen storage unit 21, and the like. The charging information and hydrogen filling rate information are transmitted via server 100 to a first electric vehicle c1, which will be described later, and the like. The communication unit 23 receives from the server 100 information such as electricity stored in the fixed power storage unit 17, the charged portable power storage device 18b, the filled hydrogen tank 21d, and reservations for the purchase or exchange of hydrogen filled in the hydrogen tank 21d.

The fourth electric vehicle c4 has a hydrogen tank holding unit 31d, a fourth communication unit 33d, and a fourth display unit 35d.

[0118] (hydrogen tank holding portion 31d) A hydrogen tank 21d is detachably attached to the hydrogen tank holding portion 31d. The hydrogen stored in the hydrogen tank 21d is converted into electricity by a fuel cell (not shown). The electric power converted by the fuel cell is supplied to a motor (not shown) of the fourth electric vehicle c4, a fourth communication unit 33d, a fourth display unit 35d, and the like.

[0119] (Fourth communication unit 33d) The fourth communication unit 33d transmits to the server 100 information such as the location information of the fourth electric vehicle c4. The fourth communication unit 33d receives from the server 100 information such as hydrogen filling information for the hydrogen tanks 21d at each of the first to third power / hydrogen supply stations 10a to 10c.

[0120] (Fourth display section 35d) The fourth display unit 35d displays charging information (not shown) including the opening hours of each of the first power / hydrogen supply station 10a to the third power / hydrogen supply station 10c, the required travel time from the current location of the fourth electric vehicle c4, the hydrogen filling status of the hydrogen tank 21d, and whether reservations are possible.

[0121] If each of the first power / hydrogen supply station 10a to the third power / hydrogen supply station 10c fills multiple types of hydrogen tanks 21d with hydrogen, it is desirable that only information related to the hydrogen tank 21d corresponding to the hydrogen tank holding unit 31d of the fourth electric vehicle c4 be displayed as the hydrogen filling information.

[0122] The hydrogen filling information displays a reservation instruction button when a reservation is possible for the purchase of a hydrogen-filled hydrogen tank 21d or an exchange for the hydrogen tank 21d held by the fourth electric vehicle c4 at any of the first power / hydrogen supply stations 10a to 10c. When a specified first operation is performed, such as touching the reservation instruction button on the fourth display unit 35d, information regarding the reservation is sent or a call is made via server 100 to the electricity / hydrogen supply station corresponding to the reservation instruction button. The transmission of information relating to the reservation includes the transmission of information about the fourth electric vehicle c4 or the user of the fourth electric vehicle c4, the expected arrival time, the type of hydrogen tank 21d to be purchased or exchanged, and the like. When a call is made, a call is initiated via the fourth communication unit 33d, and then a call is made between the user of the fourth electric vehicle c4 and the user of the corresponding electricity / hydrogen supply station.

[0123] The hydrogen filling information displays route guidance buttons from the current position of the fourth electric vehicle c4 to each of the first electricity / hydrogen supply station 10a to the third electricity / hydrogen supply station 10c. When a predetermined second operation is performed, such as touching a route guidance button on the fourth display unit 35d, a route Ru from the current position of the fourth electric vehicle c4 to the electricity / hydrogen supply station corresponding to the route guidance button is displayed. The route Ru may be a route calculated with the electricity / hydrogen supply station corresponding to the route guidance button as the final destination Dp, or, if a route to another destination has been set before the second operation is performed, the route Ru may be a route calculated with the other destination as the final destination and the electricity / hydrogen supply station corresponding to the route guidance button as a stopover.

[0124] Furthermore, when the first operation is performed, a route Ru to the electricity / hydrogen supply station corresponding to the reservation instruction button may be displayed (not shown).

[0125] The calculation of the route and other calculations related to the display of the fourth display unit 35d may be performed by the control unit of the fourth electric vehicle c4 or by the server 100.

[0126] The hydrogen filling information may include all electricity and hydrogen supply stations, but may also include only those within a range of a first distance d1 from the current location of the fourth electric vehicle c4, and / or, if the fourth electric vehicle c4 has set a route, only those within a range of a first distance d1 from the route.

[0127] In addition, the hydrogen filling information may be displayed with the electricity and hydrogen supply stations listed in order of closest straight-line distance or distance from the current location of the fourth electric vehicle c4, or, if the fourth electric vehicle c4 has set a route, closest straight-line distance or distance from the route.

[0128] In addition, the hydrogen filling information may only be displayed if it meets certain conditions, such as hydrogen filling information corresponding to the first power / hydrogen supply station 10a to the third power / hydrogen supply station 10c that has a hydrogen tank 21d filled with hydrogen, hydrogen filling information corresponding to stations where purchase or replacement can be reserved, or hydrogen filling information corresponding to stations that require a short travel time from the current location, etc.

[0129] (Server 100) The server 100 communicates with the first to third power / hydrogen supply stations 10a to 10c and the first to fourth electric vehicles c1 to c4 via the network. As will be described later, when the server 100 is located adjacent to the first power / hydrogen supply station 10a, the server 100 may be cooled based on the power supplied from the first power / hydrogen supply station 10a (see FIG. 10).

[0130] (Load test operation procedure) When a load test of the first power generating device 11 is performed, the second power generating device 12 is turned off, and power is supplied from the first power generating device 11 to the fixed power storage unit 17, the portable power storage unit 18, and the hydrogen generation device 21b. When a load test of the second power generation device 12 is performed, the first power generation device 11 is turned off, and power is supplied from the second power generation device 12 to the fixed power storage unit 17, the portable power storage unit 18, and the hydrogen generation device 21b. When the second power generation device 12 is used for purposes other than the load test, the operation is controlled so that power is not supplied from the second power generation device 12 to the hydrogen generation device 21b. When a load test is performed on an external power source to be tested that is connected to the first power / hydrogen supply station 10a, the external power source to be tested is connected to the control device 13, the first power generation device 11 and the second power generation device 12 are turned off, and power is supplied from the external power source to the fixed storage unit 17, the portable storage unit 18, and the hydrogen generation device 21b.

[0131] (Effects of using multiple power generation devices, power storage devices, and hydrogen storage units) By using the first power generating device 11 and the second power generating device 12, during the time period when power generation by the first power generating device 11 is possible, electricity and hydrogen are stored by generating electricity using the first power generating device 11. During the time period when power generation by the first power generating device 11 is not possible, electricity from the second power generating device 12 and the power storage units (fixed power storage unit 17, portable power storage unit 18) is used to drive electrical equipment such as the first load 19a and the first electric vehicle c1. The first power generating device 11 generates electricity using natural energy, and the second power generating device 12 generates electricity using hydrogen. The hydrogen used in the second power generating device 12 is hydrogen obtained in the hydrogen storage unit 21. Therefore, even if there is no external power supply, it is possible to obtain and store power and hydrogen within the first power / hydrogen supply station 10a. The electric power stored in the electric storage unit (fixed electric storage unit 17, portable electric storage unit 18) may be reduced by discharging. The hydrogen stored in the hydrogen tank 21d of the hydrogen storage unit 21 is unlikely to be released naturally. Therefore, for short-term storage, electricity is stored in the storage units (fixed storage unit 17, portable storage unit 18), and for long-term storage, hydrogen is absorbed into the hydrogen tank 21d, thereby enabling the electricity generated by the first power generation device 11 to be stored efficiently. In addition, it is possible to supply electricity and hydrogen to various types of electrical equipment, including directly supplying electricity, directly supplying hydrogen, supplying a portable power storage unit 18, and supplying a container containing hydrogen (portable hydrogen tank 21d). Furthermore, by using water obtained from moisture in the air as the electrolyte, it becomes possible to continuously store hydrogen even when there is little supply of materials from the outside.

[0132] (Effects of using a power storage device and a hydrogen generation device as a load test area) Using both the power storage device (such as the fixed power storage unit 17) and the hydrogen storage device (such as the hydrogen generator 21b) in the first power / hydrogen supply station 10a, it becomes possible to perform load tests on the power generation device (such as the first power generation device 11) under both large and small loads. The power generated during the load test can be stored as power or hydrogen, resulting in little energy loss.

[0133] (Effect of using electrolytic load test area for fine adjustment of load) By controlling the movement of the electrolysis electrodes or the supply of the electrolyte, it becomes possible to adjust the load amount more minutely than by controlling the number of power storage devices used in the rechargeable load test area.

[0134] (The effect of being able to adjust usage priority) Even during times when power generation by the first power generation device 11 is not possible, power can be supplied using multiple power supply devices, namely, the power storage units (fixed power storage unit 17, portable power storage unit 18) and the second power generation device 12. However, it may happen that the power supply device required does not match the power supply device actually used. By setting an optimal usage priority, it becomes possible to use the stored electricity and hydrogen efficiently.

[0135] (Effect of the control device 13 determining the priority order of use based on the usage status of the power storage unit, etc.) Losses due to natural discharge can be reduced by maintaining the frequency of use of fixed power storage unit 17 and portable power storage unit 18 at a certain level or higher. Furthermore, maintaining the frequency of use of second power generation device 12 at a certain level or higher can reduce the possibility of deterioration of second power generation device 12 due to non-use and the possibility of deterioration of fixed power storage unit 17 and portable power storage unit 18 due to excessive charging and discharging.

[0136] (Effect of using a strain sensor) By using a strain sensor that measures strain as the detection device 21f, the degree of hydrogen filling can be obtained from the degree of strain of the hydrogen storage alloy that has expanded due to absorption, making it possible to obtain a more accurate degree of hydrogen filling than a method that calculates the degree based on the flow rate of hydrogen, etc. flowing into the hydrogen tank 21d.

[0137] (Effects of supplying hydrogen etc. directly to electrical equipment) The power storage unit can supply power via a cable to electrical equipment that directly charges the vehicle battery, such as a plug-in hybrid car (first electric vehicle c1).The hydrogen tank 21d and other components can fill hydrogen via a flexible tube to electrical equipment that directly fills the on-board fixed hydrogen storage device 31c of a fuel cell vehicle (third electric vehicle c3).

[0138] (Effect of using power obtained from load testing) The power obtained in the load test of the power supply under test can be used to store electricity in the portable electricity storage device 18b and to fill the portable hydrogen tank 21d with hydrogen.

[0139] (Effect of notifying charging status) It is desirable that the first electric vehicle c1 that uses the power stored in the in-vehicle power storage device 31a be able to obtain information on stores where power can be purchased from the charged fixed power storage unit 17 or the like. Charging information including the charging status of the fixed power storage unit 17 is displayed on the first display unit 35a of the first electric vehicle c1 that uses the in-vehicle power storage device 31a. This allows the user of the first electric vehicle c1 to visually recognize stores (electricity / hydrogen supply stations) that sell available electricity and are located near the first electric vehicle c1.

[0140] (The effect of informing the charging status of multiple electricity and hydrogen refueling stations) By providing information on multiple stores (electricity and hydrogen supply stations) that sell available electricity, it becomes easier for the user of the first electric vehicle c1 to select the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), travel to the store becomes easier.

[0141] (Effect of notifying charging status) It is desirable that the second electric vehicle c2 using the portable power storage device 18b be able to obtain information about stores where a charged portable power storage device 18b can be purchased. Charging information including the charging status of the portable power storage device 18b is displayed on the second display unit 35b of the second electric vehicle c2 that uses the portable power storage device 18b. This allows the user of the second electric vehicle c2 to visually recognize stores (electricity / hydrogen supply stations) that sell portable electricity storage devices 18b that can be purchased or exchanged and are located near the second electric vehicle c2.

[0142] (The effect of informing the charging status of multiple electricity and hydrogen refueling stations) By providing information on multiple stores (electricity / hydrogen supply stations) that sell portable electricity storage devices 18b that can be purchased or replaced, it becomes easier for the user of the second electric vehicle c2 to select the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), travel to the store becomes easier.

[0143] (Effect of notifying hydrogen filling status) In the third electric vehicle c3 that uses hydrogen stored in the on-board fixed hydrogen storage device 31c, it is desirable to be able to obtain information on stores where hydrogen can be purchased from the hydrogen tank 21d that has already been filled with hydrogen. Hydrogen filling information including the hydrogen filling status of the hydrogen tank 21d is displayed on the third display unit 35c of the third electric vehicle c3 that uses the in-vehicle fixed hydrogen storage device 31c. This makes it possible for the user of the third electric vehicle c3 to visually recognize stores (electricity / hydrogen supply stations) that sell available electricity and are located near the third electric vehicle c3.

[0144] (The effect of informing the charging status of multiple electricity and hydrogen refueling stations) By providing information on multiple stores (electricity and hydrogen supply stations) that sell hydrogen for purchase, it becomes easier for users of the third electric vehicle c3 to select the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), travel to the store becomes easier.

[0145] (Effect of notifying hydrogen filling status) For the fourth electric vehicle c4 that uses the hydrogen tank 21d, it is desirable to be able to obtain information on stores where the hydrogen tank 21d filled with hydrogen can be purchased. Hydrogen filling information including the hydrogen filling status of the charging status hydrogen tank 21d is displayed on the fourth display unit 35d of the fourth electric vehicle c4 that uses the hydrogen tank 21d. This allows the user of the fourth electric vehicle c4 to visually identify stores (electricity / hydrogen supply stations) that sell hydrogen tanks 21d that can be purchased or replaced and are located near the fourth electric vehicle c4.

[0146] (The effect of informing the charging status of multiple electricity and hydrogen refueling stations) By providing information on multiple stores (electricity / hydrogen supply stations) that sell hydrogen tanks 21d that can be purchased or replaced, it becomes easier for users of the fourth electric vehicle c4 to select the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), travel to the store becomes easier.

[0147] (The hydrogen generation device 21b is not limited to electrolysis.) In the first embodiment, the hydrogen generation device 21b is described as a device that generates hydrogen by electrolysis of an electrolyte solution. However, the method for generating hydrogen is not limited to electrolysis of the electrolyte. For example, the hydrogen generating device 21b may be a device that heats an organic hydride that reversibly releases hydrogen as a catalytic reaction. In this case, an organic hydride supply unit is provided in place of the electrolyte supply unit 21a.

[0148] (Application example of power and hydrogen supply station, second embodiment) Next, a second embodiment will be described. The first power / hydrogen supply station 10a of the second embodiment differs from the first power / hydrogen supply station 10a of the first embodiment in that the fixed power storage unit 17 has two power storage units (first power storage unit 17a and second power storage unit 17b), and the hydrogen storage unit 21 has a hydrogen tank 21d and a liquid tank 21i that stores hydrogen as an organic hydride. The following description will focus on the differences from the first embodiment. The second electric power / hydrogen supply station 10b and the third electric power / hydrogen supply station 10c of the second embodiment may also have the same configuration as the first electric power / hydrogen supply station 10a of the second embodiment.

[0150] (First power generating unit 11) The first power generating device 11 of the second embodiment has a DC power generating device 11a and an AC power generating device 11b.

[0151] (DC power generator 11a) The DC power generation device 11a is a power generation device (first renewable energy-derived power generation device) that generates power based on natural energy (renewable energy), such as a solar power generation device or a wind power generation device. The DC power generator 11a is always in a state where it can generate power. The DC power generation device 11a is installed on the roof of the building 25 or the like. The electric power obtained by DC power generation device 11a is supplied to first power storage unit 17a and second power storage unit 17b via first conversion unit 13a1 and first switching unit 22a.

[0152] (AC power generator 11b) The AC power generation device 11b is a power generation device (second renewable energy-derived power generation device) that generates power based on natural energy (renewable energy), such as a wind power generation device. The AC power generation device 11b is always in a state where it can generate power. However, when the wind force received by AC power generation device 11b exceeds a predetermined wind force, AC power generation device 11b is put into a state in which it is unable to generate power. The AC power generating device 11b is installed on the roof of the building 25 or the like. The power obtained by AC power generation device 11b is supplied to first power storage unit 17a and second power storage unit 17b via second conversion unit 13a2 and second switching unit 22b.

[0153] (Second power generating unit 12) The second power generator 12 is a power generator (fuel cell) that generates electricity based on hydrogen. The second power generation device 12 is installed inside the building 25 or on the roof of the building 25, for example.

[0157] (Third conversion unit 13a3) Third conversion unit 13a3 is provided between input terminal unit 24a and first power storage unit 17a. Third conversion unit 13a3 includes an AC / DC converter. Power from a power supply device (e.g., second power storage unit 17b) connected to input terminal 24a is converted by third conversion unit 13a3 into a predetermined voltage and a predetermined current, and then supplied to first power storage unit 17a.

[0158] (Fourth conversion unit 13a4) Fourth conversion unit 13a4 is provided between first power storage unit 17a and first output terminal unit 24b1. Fourth conversion unit 13a4 includes a DC / AC inverter. The power stored in first power storage unit 17a is converted by fourth conversion unit 13a4 into a predetermined voltage and a predetermined current, and is supplied to an electrical device (e.g., a load in building 25) connected to first output terminal unit 24b1.

[0159] (Fifth conversion unit 13a5) Fifth conversion unit 13a5 is provided between second power storage unit 17b and second output terminal unit 24b2.

The power stored in second power storage unit 17b is converted by fifth conversion unit 13a5 into a predetermined voltage and a predetermined current, and is supplied to an electrical device connected to second output terminal unit 24b2.

[0160] (Other conversion parts) Furthermore, a conversion unit (such as a DC / DC converter) that converts the power obtained by the second power generation device 12 into a predetermined voltage and a predetermined current may be provided between the second power generation device 12 and the second power storage unit 17b.

[0161] (Control device 13) The control device 13 controls the operation of each part. The control device 13 is installed inside a building 25 or the like.

[0162] (Control of hydrogen supply to hydrogen tank 21d) For example, if the charging rate R1a of the first storage unit 17a is higher than or equal to the full charge threshold Thrf (Thrf>Thr1) and the power P supplied from the first power generation device 11 (DC power generation device 11a, AC power generation device 11b) is higher than or equal to the power threshold Thp, the control device 13 determines that surplus power is being generated and drives the hydrogen storage unit 21. Specifically, the control device 13 drives the hydrogen generation device 21b to generate hydrogen, and drives the heat retention / cooling unit 21c to fill the generated hydrogen into the hydrogen tank 21d.

[0163] (Control of hydrogen supply to liquid tank 21i) If the hydrogen filling rate R3 of the hydrogen tank 21d is higher than or equal to the second hydrogen filling rate threshold Thr4, the control device 13 determines that the hydrogen tank 21d is sufficiently filled with hydrogen, and drives the hydrogen addition device 21h to add the generated hydrogen to aromatic compounds such as toluene to produce organic hydrides (saturated condensed ring hydrocarbons) such as methylcyclohexane, which are then stored in the liquid tank 21i. However, the hydrogen generated in the hydrogen generation device 21b may be supplied to the hydrogen addition device 21h before being supplied to the hydrogen tank 21d.

[0164] (Control of hydrogen supply to second power generating unit 12) When the hydrogen filling rate R3 of the hydrogen tank 21d is higher than or equal to the second hydrogen filling rate threshold Thr4 and the liquid volume Q of the liquid tank 21i is higher than or equal to the tank capacity threshold Thq, the control device 13 drives the heat retention / cooling unit 21c to supply hydrogen from the hydrogen tank 21d to the second power generation device 12, and / or drives the dehydrogenation device 21j to separate hydrogen from the organic hydride in the liquid tank 21i and supply the separated hydrogen to the second power generation device 12. The control device 13 also drives the second power generation device 12.

[0165] (Switching control of switching unit 22) However, if the hydrogen filling rate R3 of the hydrogen tank 21d is higher than or equal to the second hydrogen filling rate threshold Thr4, and the liquid volume Q of the liquid tank 21i is higher than or equal to the tank capacity threshold Thq, and the charging rate R1a of the first storage unit 17a is higher than or equal to the full charge threshold Thrf, and the power P supplied from the first power generation device 11 (DC power generation device 11a, AC power generation device 11b) is higher than or equal to the power threshold Thp, the control device 13 drives the first switching unit 22a and the second switching unit 22b to switch the destination of the power supply from the first power generation device 11 from the first storage unit 17a to the second storage unit 17b.

[0166] (Control of power supply from second power storage unit 17b to first power storage unit 17a) In addition, when the charging rate R1a of the first storage unit 17a is lower than the full charge threshold Thrf and the charging rate R1b of the second storage unit 17b is higher than or equal to the full charge threshold Thrf, the control device 13 causes the second storage unit 17b to supply power to the first storage unit 17a via the second output terminal unit 24b2 and the input terminal unit 24a.

[0167] (Fixed power storage unit 17) The fixed power storage unit 17 of the second embodiment has a first power storage unit 17a and a second power storage unit 17b.

[0168] (First power storage unit 17a) First power storage unit 17a has a power storage device that stores power from DC power generation device 11a and the like. First power storage unit 17a is fixed to a predetermined position on building 25 without consideration of whether it can be attached or detached. However, first power storage unit 17a may be held at a predetermined position on building 25 in a detachable state.

[0169] The first power storage unit 17a supplies the stored power to an electric device (for example, the first load 19a) connected to the first output terminal unit 24b1 and the hydrogen generation device 21b.

[0170] (Second power storage unit 17b) Second power storage unit 17b has a power storage device that stores power from DC power generation device 11a etc. The power storage device of second power storage unit 17b stores power from second power generation device 12. Therefore, second power storage unit 17b can also be used as a power storage unit for a fuel cell. Second power storage unit 17b is fixed to a predetermined position on building 25 without consideration of whether it can be attached or detached. However, second power storage unit 17b may be held at a predetermined position on building 25 in a detachable state.

[0171] The power stored in second power storage unit 17b is supplied to the electric devices connected to second output terminal 24b2 (e.g., first load 19a, input terminal 24a, etc.) and hydrogen generation device 21b. However, the power supply from second power storage unit 17b to hydrogen generation device 21b may be omitted. The charge capacity of the power storage device of first power storage unit 17a is larger (approximately three times) than the charge capacity of the power storage device of second power storage unit 17b.

[0172] Furthermore, portable power storage unit 18 described in the first embodiment may be provided in addition to first power storage unit 17a and second power storage unit 17b.

[0173] (hydrogen storage unit 21) The hydrogen storage unit 21 of the second embodiment has an electrolyte supply unit 21a including a water intake unit 21a1, a hydrogen generation device 21b, a heat retention and cooling unit 21c, a hydrogen tank 21d, a connecting pipe 21e, a detection device 21f, a hydrogen supply unit 21g, a hydrogen addition device 21h, a liquid tank 21i, and a dehydrogenation device 21j. Of these, the hydrogen tank 21d and the liquid tank 21i function as storage units.

[0174] (Electrolyte supply section 21a) The configuration of the electrolytic solution supply unit 21a is the same as the configuration of the electrolytic solution supply unit 21a of Embodiment 1. That is, the electrolytic solution supply unit 21a is provided with a water intake unit 21a1 (not shown in FIG. 9).

[0175] (Hydrogen generator 21b) The hydrogen generator 21b is configured with a water electrolysis device or the like, and generates hydrogen by performing electrolysis based on the power supplied from the DC power generator 11a or the like. The electrolytic solution supply unit 21a and the hydrogen generation device 21b may be configured as separate bodies or may be configured as an integrated body.

[0176] The hydrogen generator 21b communicates with the second power generator 12, the hydrogen tank 21d, the hydrogen supply unit 21g, the hydrogen addition device 21h, and the hydrogen supply unit 21g via a communication pipe 21e. The communicating pipe 21e is provided with a valve (a flow rate control device for the communicating pipe 21e) that controls the flow of hydrogen, such as the amount of hydrogen supplied from the hydrogen generating device 21b. Figure 9 shows an example in which an eleventh valve b1 is provided in the communicating pipe 21e between the hydrogen generating device 21b and the hydrogen adding device 21h, a twelfth valve b2 is provided between the hydrogen generating device 21b and the hydrogen supply unit 21g, a thirteenth valve b3 is provided between the hydrogen generating device 21b and the dehydrogenation device 21j, a fourteenth valve b4 is provided between the hydrogen generating device 21b and the hydrogen tank 21d, and a fifteenth valve b5 is provided between the second power generating device 12 and the hydrogen generating device 21b. The valves (11th valve b1 to 15th valve b5) of the communicating pipe 21e function as a flow rate control device (first flow rate control device) for the communicating pipe 21e that controls the supply amount of hydrogen obtained in the hydrogen generating device 21b. However, the first flow rate control device may be composed of other members. When hydrogen is supplied from the hydrogen generation device 21b to the hydrogen addition device 21h, the eleventh valve b1 in the communication pipe 21e is opened, and the other valves (the twelfth valve b2 to the fifteenth valve b5) are closed. The valves (the eleventh valve b1 to the fifteenth valve b5) provided in the communication pipe 21e are electrically opened and closed under the control of the control device 13, for example.

[0177] (Thermal insulation cooling part 21c) The configuration of the heat retention / cooling unit 21c is similar to the configuration of the heat retention / cooling unit 21c of the first embodiment.

[0178] (Hydrogen tank 21d) The configuration of the hydrogen tank 21d is similar to the configuration of the hydrogen tank 21d in the first embodiment. In the second embodiment, an example in which only one hydrogen tank 21d is provided is shown, but similar to the first embodiment, a plurality of hydrogen tanks 21d may be provided. Although not shown in FIG. 9 and the like, a buffer tank 21d1 and a pressure reducing device 21d2 may be provided. The configuration of the detection device 21f is similar to the configuration of the detection device 21f of the first embodiment.

[0179] (Hydrogen supply unit 21g) Like the hydrogen supply unit 21g of the first embodiment, the hydrogen supply unit 21g is detachably connected to the third electric vehicle c3 and the like, and supplies hydrogen from the hydrogen tank 21d and the like to the on-board fixed hydrogen storage device 31c of the third electric vehicle c3. Furthermore, similarly to the first embodiment, a high-pressure hydrogen tank or the like may be detachably connected to the hydrogen supply unit 21g. In this case, hydrogen from the high-pressure hydrogen tank or the like may be supplied to the hydrogen tank 21d or the like.

[0180] (Hydrogenation unit 21h) The hydrogenation device 21h adds hydrogen to aromatic compounds in a hydrogenation reaction to produce organic hydrides. A catalyst (first catalyst 21h1, see FIG. 13) used to activate the hydrogenation reaction is heated by a catalyst heating device for the hydrogenation reaction. However, as shown in a fourth embodiment described later, the first catalyst 21h1 may be heated using heat obtained by a device other than the catalyst heating device for the hydrogenation reaction, such as a solar water heater 20.

[0181] (Liquid Tank 21i) The liquid tank 21i stores the organic hydride produced in the hydrogenation device 21h. The liquid tank 21i is provided with a liquid level detector (not shown) that detects the liquid level Q in the tank.

[0182] (Dehydrogenator 21j) The dehydrogenation device 21j separates hydrogen from organic hydride through a dehydrogenation reaction. A catalyst (second catalyst 21j1, see FIG. 13) used to activate the dehydrogenation reaction is heated by a catalyst heating device for the dehydrogenation reaction (not shown). However, as shown in a fourth embodiment described later, the second catalyst 21j1 may be heated using heat obtained by a device other than the catalyst heating device for the dehydrogenation reaction, such as a solar water heater 20.

[0183] (Aromatic Compound Tank) The hydrogen storage section is provided with a tank (not shown) for storing aromatic compounds to be supplied to the hydrogenation device 21h, and a tank (not shown) for storing aromatic compounds purified by hydrogen separation in the dehydrogenation device 21j.

[0184] The material to which hydrogen is added (substance to be hydrogenated) is not limited to aromatic compounds, but may also be aldehydes, ketones, or the like.

[0185] (Switching unit 22) The switching unit 22 of the second embodiment has a first switching unit 22a and a second switching unit 22b.

[0186] (First switching unit 22a) First switching unit 22a switches the supply destination of power from DC power generation device 11a between first power storage unit 17a and second power storage unit 17b.

[0187] (Second switching unit 22b) Second switching unit 22b switches the destination of power supply from AC power generation device 11b between first power storage unit 17a and second power storage unit 17b.

[0188] (Switching control) Normally, power from the DC power generator 11a is supplied to the first storage unit 17a via the first conversion unit 13a1 and the first switching unit 22a, and power from the AC power generator 11b is supplied to the first storage unit 17a via the second conversion unit 13a2 and the second switching unit 22b. However, when the first storage unit 17a is fully charged and the subsequent hydrogen tank 21d and liquid tank 21i are highly filled with hydrogen, power from the DC power generator 11a is supplied to the second storage unit 17b via the first conversion unit 13a1 and the first switching unit 22a, and power from the AC power generator 11b is supplied to the second storage unit 17b via the second conversion unit 13a2 and the second switching unit 22b.

[0189] Specifically, when the hydrogen filling rate R3 of the hydrogen tank 21d is higher than the second hydrogen filling rate threshold Thr4, the liquid volume Q of the liquid tank 21i is higher than the tank capacity threshold Thq, the charging rate R1a of the first storage unit 17a is higher than the full charge threshold Thrf, and the power P supplied from the first power generation device 11 is higher than the power threshold Thp, the supply destination of the power from the first power generation device 11 is switched from the first storage unit 17a to the second storage unit 17b.

[0190] (Input / output terminal section 24) The input / output terminal section 24 has an input terminal section 24a, a first output terminal section 24b1, and a second output terminal section 24b2.

[0191] (input terminal section 24a) Input terminal unit 24a is detachably connected to an external power source (for example, a commercial power source) or an internal power source (second power storage unit 17b). Electric power from an external power supply connected to input terminal unit 24a is supplied to first power storage unit 17a via input terminal unit 24a and third conversion unit 13a3. The input terminal 24a may be connected to the second output terminal 24b2 via a cable. FIG. 9 shows an example in which the input terminal section 24a is connected to the second output terminal section 24b2 via a cable. The input terminal unit 24a may be connected to the first electric vehicle c1 as an external power source. In this case, the third conversion unit 13a3 and the input terminal unit 24a function as the second converter 14b of the charger 14 described in the first embodiment.

[0192] (1st output terminal section 24b1) The first output terminal 24b1 is connected to an external electric device (for example, the first electric vehicle c1) or an internal electric device (for example, the first load 19a). The power from first power storage unit 17a is supplied to an electrical device connected to first output terminal unit 24b1 via fourth conversion unit 13a4 and first output terminal unit 24b1. When the first output terminal unit 24b1 is connected to the first electric vehicle c1, the fourth conversion unit 13a4 and the first output terminal unit 24b1 function as the first converter 14a of the charger 14 described in the first embodiment. Note that power may be supplied from first power storage unit 17a to internal electrical devices such as first load 19a without going through first output terminal unit 24b1. In this case, power from first power storage unit 17a is supplied to first load 19a and the like via fourth conversion unit 13a4.

[0193] (Second output terminal section 24b2) The second output terminal 24b2 is connected to an external electric device (for example, the first electric vehicle c1) or an internal electric device (for example, the first load 19a). The power from second power storage unit 17b is transmitted via fifth conversion unit 13a5 and second output terminal unit 24b2 to an electrical device connected to second output terminal unit 24b2. The second output terminal 24b2 may be connected to the input terminal 24a via a cable. When the second output terminal unit 24b2 is connected to the first electric vehicle c1, the fifth conversion unit 13a5 and the second output terminal unit 24b2 function as the charger 14 described in the first embodiment. Note that power may be supplied from second power storage unit 17b to internal electrical devices such as first load 19a without passing through second output terminal unit 24b2. In this case, power from second power storage unit 17b is supplied to first load 19a and the like via fifth conversion unit 13a5.

[0194] (Building 25) The building 25 is a building in which the first load 19a and the like are installed, similarly to the first embodiment. The second power generation device 12, the first power storage unit 17a, the second power storage unit 17b, the hydrogen generation device 21b, the hydrogen tank 21d, the hydrogen addition device 21h, the liquid tank 21i, the dehydrogenation device 21j, etc. are arranged inside the building 25.

[0195] (Effects of providing first power storage unit 17a, second power storage unit 17b, and hydrogen storage unit 21) The power from the first power storage unit 17a is supplied to the hydrogen generation device 21b. The hydrogen obtained by the hydrogen generation device 21b is stored in the storage section (hydrogen tank 21d, liquid tank 21i) and is used for power generation by the second power generation device 12. The power obtained by the second power generating device 12 is not supplied directly to the first power storage unit 17a, but is supplied to the second power storage unit 17b, and then converted from DC to AC and from AC to DC via the fifth conversion unit 13a5, etc., before being supplied to the first power storage unit 17a. Therefore, compared to a configuration in which the power obtained by second power generation device 12 is directly supplied to first power storage unit 17a, it is possible to more easily control (voltage, current, timing, etc.) the power returned to first power storage unit 17a.

[0196] (The effect of having two types of hydrogen storage devices) Devices that store energy obtained by the first power generation device 11 and the like as electric power (first power storage unit 17a, second power storage unit 17b) and devices that store energy as hydrogen (hydrogen tank 21d, liquid tank 21i) are used in combination. Therefore, even when first power storage unit 17a or the like is fully charged, it is possible to convert surplus power into hydrogen and store a large amount of energy. In addition, if the power supply from the first power generation device 11 is insufficient and the power stored in the first storage unit 17a, etc. is also insufficient, the hydrogen in the storage unit (hydrogen tank 21d, liquid tank 21i) can be converted into electricity, and this electricity can be supplied to electrical equipment such as the first load 19a. The capacity of a storage unit that stores hydrogen can be increased relatively easily compared to a storage battery that stores electricity. Therefore, surplus electricity can be easily stored as hydrogen using a storage unit (hydrogen tank 21d, liquid tank 21i) of an appropriate size based on the difference between the electricity obtained by the first power generation device 11 and the electricity required by electrical equipment such as the first load 19a. In addition to supplying power to external devices, it can also supply hydrogen.

[0197] (Effects of controlling electricity storage and hydrogen accumulation) Charging, hydrogen generation, hydrogen storage, power generation based on hydrogen, etc. can be controlled according to the charge level of first power storage unit 17a and second power storage unit 17b, the hydrogen filling level of hydrogen tank 21d, and the liquid level in liquid tank 21i.

[0198] In the second embodiment, a solar power generation device having a power generation capacity of 1.5 kW is used as the DC power generation device 11a. Furthermore, a wind power generator having a power generating capacity of 300 W is used as the AC power generator 11b. The second power generator 12 is a fuel cell with a rated output power of 3 kW, a rated output voltage of DC 48 V, a hydrogen supply rate of 2670 SL (Standard Litter) / h, and a hydrogen pressure of 0.06 to 0.07 MPa. Furthermore, a DC / DC converter with an output voltage of 48V is used as the first conversion unit 13a1. Furthermore, an AC / DC converter with an output voltage of 48V is used as the second conversion unit 13a2. Furthermore, as the third conversion unit 13a3, an AC / DC converter with an input voltage of three-phase 200V, an input power of 3kW to 7.5kW, and an output power of 15kWh or less is used. Furthermore, as the fourth conversion unit 13a4, a DC / AC inverter with an output voltage of three-phase 200V and an output power of 12kW is used. Furthermore, as the fifth conversion unit 13a5, a DC / AC inverter with an output voltage of three-phase 200V and an output power of 3kW is used. Also, as first power storage unit 17a, three lithium ion batteries, each having a voltage of 48V and an amount of power of 5kWh, connected in series or in parallel are used. Second power storage unit 17b is provided with one lithium ion battery with a voltage of 48V and an amount of power of 5kWh. Furthermore, as the hydrogen generator 21b, a water electrolysis device with a hydrogen generation rate of 183 NL / h, a hydrogen pressure of 0.45 MPa, an electrolysis voltage of DC 48V, a supply power of 1500 W, and an input voltage of DC 48V is used. Furthermore, a hydrogen storage alloy container with a capacity of 10,000 NL is used as the hydrogen tank 21d.

[0199] In this case, one first power / hydrogen supply station 10a can independently supply power to one apartment building, etc., without needing to be supplied with power from a commercial power source. Also, because the specifications (capacity, pressure, etc.) of each part are relatively small, compared to configurations where the specifications of each part are large, applications to various authorities when installing a hydrogen tank 21d, etc. in a building 25 can be made more easily. However, the values ​​of the capacity of each part are merely examples and are not limited to these.

[0200] Next, an example will be described in which the server 100 is cooled using electric power from the first electric power / hydrogen supply station 10a (third embodiment, see FIG. 10). In the third embodiment, an example is shown in which power is supplied to the heat exchange unit 130 and the like from the first output terminal unit 24b1 of the first power / hydrogen supply station 10a. However, power may be supplied to the heat exchanger 130 and the like from the second output terminal 24b2 of the first power / hydrogen supply station 10a.

[0201] The first power / hydrogen supply station 10a of the third embodiment has a first power generation device 11, a second power generation device 12, a control device 13, a first conversion device 13a, a fixed power storage unit 17, a hydrogen storage unit 21, a switching unit 22, and an input / output terminal unit 24. A heat medium circulating device (liquid tank 110, liquid transport unit 120, heat exchange unit 130, and switching device 140) is connected to a first electric power / hydrogen supply station 10a of the third embodiment. The first electric power / hydrogen supply station 10a and the heat medium circulator of the third embodiment constitute a cooling device for cooling a computer such as a server 100.

[0202] The configurations of the first power generation device 11, the second power generation device 12, the control device 13, the first conversion device 13a, the fixed power storage unit 17, the hydrogen storage unit 21, the switching unit 22, and the input / output terminal unit 24 of the third embodiment are similar to those of the first power generation device 11, the second power generation device 12, the control device 13, the first conversion device 13a, the fixed power storage unit 17, the hydrogen storage unit 21, the switching unit 22, and the input / output terminal unit 24 of the second embodiment.

[0203] The following description will focus on the differences from the second embodiment, that is, the configuration of the heat medium circulator. The first electric power / hydrogen supply station 10a of the third embodiment may have a charger 14, a station display unit 15, a station operation unit 16, and a communication unit 23, similar to the first embodiment. Furthermore, the second electric power / hydrogen supply station 10b and the third electric power / hydrogen supply station 10c of the third embodiment may also have the same configuration as the first electric power / hydrogen supply station 10a of the third embodiment.

[0204] (liquid tank 110) The liquid vat 110 holds at least heat-generating components (CPU, storage, etc.) of a computer such as the server 100, immersed in the first heat medium. That is, the liquid vat 110 holds the computer and the first heat medium (cooling solution) for cooling the computer. The first heat medium is made of an insulating liquid such as a fluorine-based inert liquid or pure water.

[0205] (liquid delivery unit 120) The liquid transport unit 120 has a pump, a compressor, etc., and is used to circulate the first heat medium between the liquid tank 110 and the heat exchange unit .

[0206] (Heat exchange part 130) The heat exchanger 130 has a fan 130a, a sprayer 130b, etc., and cools the first heat medium from the liquid tank 110 by heat exchange. The fan 130a supplies cooling air to the pipe through which the high-temperature first heat medium passes. The spray unit 130b sprays mist of cooling water onto at least one of the pipe through which the high-temperature first heat medium passes and the fan 130a. However, the heat exchanger 130 may be configured to cool the first heat medium using a refrigerant such as water in a cooling tower or the like instead of the fan 130a.

[0207] The liquid tank 110, the liquid transfer unit 120, and the heat exchange unit 130 constitute a heat medium circulating device (chiller) for cooling the server 100.

[0208] (Switching device 140) The server 100 connects the commercial power supply to the first output terminal 24b1 via the switching device 140. The switching device 140 normally supplies power from a commercial power source to the server 100, and when the power supply from the commercial power source is interrupted, performs timing synchronization and then controls switching so that power from the first output terminal unit 24b1 is supplied to the server 100.

[0209] (Effect of the cooling device including the liquid transfer unit 120 cooling the server 100, etc.) Because a liquid is used as the first heat medium, the server 100 can be cooled more efficiently than in a cooling system that uses a gas such as air. Cooling using heat medium circulation is performed based on electric power from two types of power generation devices (first power generation device 11 and second power generation device 12). Therefore, compared to a configuration in which cooling using heat medium circulation is performed based on electric power from a commercial power source, it is possible to reduce the possibility of falling into a state in which cooling is not possible due to a power outage or other interruption in the power supply from the commercial power source.

[0210] (Cooling effect using spray section 130b) By spraying the mist of cooling water from the spray unit 130b onto a pipe through which the first heat medium passes, cooling using the heat of vaporization becomes possible.

[0211] (Effects of supplying power to the server 100, etc. via the switching device 140) For computers such as server 100 that normally run on power from a commercial power source, even when the power supply from the commercial power source is cut off due to a power outage or other reason, it is possible to maintain the operation of the computer using power from first power storage unit 17a, etc.

[0212] The object to be cooled by the heat medium circulator of the third embodiment is not limited to the server 100 of the electric power and hydrogen supply system 1, i.e., the server 100 that communicates with the first electric power and hydrogen supply station 10a to the third electric power and hydrogen supply station 10c and the first electric vehicle c1 to the fourth electric vehicle c4 via a network. The heat medium circulator of the third embodiment may also be used to cool a server or computer separate from the electric power and hydrogen supply system 1.

[0213] (Example of heat transfer medium circulator arrangement) In the third embodiment, an example has been described in which the heat medium circulating device including the heat exchanger 130 and the like is configured as a separate entity from the first power / hydrogen supply station 10a. However, the components constituting the first power / hydrogen supply station 10a (other than the first power generator 11) and the components constituting the heat medium circulator may be provided inside a single housing 25 (e.g., a 20-foot container) (see FIG. 11). Even in this case, the first power generator 11 is disposed on the top surface of the housing. In this case, by carrying the single housing 25, the server 100 can be operated in various places without relying on an external power supply such as a commercial power source.

[0214] (Application example of power and hydrogen supply station, fourth embodiment) Next, a fourth embodiment will be described. The first electric power / hydrogen supply station 10 a of the fourth embodiment differs from the first electric power / hydrogen supply station 10 a of the third embodiment in that it has a solar water heater 20 . Furthermore, heat is supplied from a heat generating portion such as the solar water heater 20 to a portion requiring heat such as the hydrogen tank 21d. The following description will focus on the differences from the third embodiment.

[0215] The first power / hydrogen supply station 10a of the fourth embodiment has a first power generation device 11, a second power generation device 12, a control device 13, a first conversion device 13a, a fixed power storage unit 17, a solar water heater 20, a hydrogen storage unit 21, a switching unit 22, and an input / output terminal unit 24 (see Figure 12). A heat medium circulating device (liquid tank 110, liquid transfer unit 120, heat exchange unit 130, and switching device 140) is connected to the first power / hydrogen supply station 10a of the fourth embodiment. As in the third embodiment, the first power / hydrogen supply station 10a and the heat medium circulating device may be configured as separate entities, or may be configured inside a single housing 25.

[0216] The configurations of the first power generation device 11, the second power generation device 12, the control device 13, the first conversion device 13a, the fixed power storage unit 17, the hydrogen storage unit 21, the switching unit 22, the input / output terminal unit 24, the building 25, the server 100, the liquid tank 110, the liquid transfer unit 120, the heat exchange unit 130, and the switching device 140 of the fourth embodiment are the same as those of the first power generation device 11, the second power generation device 12, the control device 13, the first conversion device 13a, the fixed power storage unit 17, the hydrogen storage unit 21, the switching unit 22, the input / output terminal unit 24, the building 25, the server 100, the liquid tank 110, the liquid transfer unit 120, the heat exchange unit 130, and the switching device 140 of the third embodiment.

[0217] The first electric power / hydrogen supply station 10a of the fourth embodiment may also have a charger 14, a station display unit 15, a station operation unit 16, and a communication unit 23, similar to the first embodiment. Furthermore, the second electric power / hydrogen supply station 10b and the third electric power / hydrogen supply station 10c of the fourth embodiment may also have the same configuration as the first electric power / hydrogen supply station 10a of the fourth embodiment. In the fourth embodiment, an example is shown in which power is supplied to the heat exchanger 130 and the like from the first output terminal 24b1 of the first power / hydrogen supply station 10a. However, power may be supplied to the heat exchanger 130 and the like from the second output terminal 24b2 of the first power / hydrogen supply station 10a.

[0218] (Solar water heater 20) The solar water heater 20 is a device that heats cold water using solar heat, and includes a heat collector that collects solar heat to generate hot water, and a hot water storage tank that stores the hot water generated by the heat collector. The heat collector of the solar water heater 20 is provided on the top of the building 25 or the like.

[0219] The water obtained in the water intake section 21a1 is supplied to the heat collector of the solar water heater 20 via the electrolyte supply section 21a or directly without via the electrolyte supply section 21a. The hot water in the hot water storage tank of the solar water heater 20 (hot water obtained by the solar water heater 20) is supplied to the hydrogen generation device 21b. Therefore, in the fourth embodiment, hot water is supplied to the hydrogen generation device 21b instead of cold water.

[0220] By using hot water, it is possible to increase the reaction rate of electrolysis and reduce the power consumption required to obtain the desired hydrogen, compared to when cold water is used. The hot water obtained by the solar water heater 20 may not only be supplied to the hydrogen generation device 21b, but may also be used for showering, etc.

[0221] When moisture in the air is condensed and the condensed water is heated by the solar water heater 20, it becomes possible to operate each part of the first power / hydrogen supply station 10a without obtaining a second heat medium supply from the outside as much as possible.

[0222] In addition, the hot water in the hot water storage tank of the solar water heater 20 (hot water obtained by the solar water heater 20) or the heat transferred from the hot water is supplied to components that require heating in the first power / hydrogen supply station 10a (hydrogen tank 21d, catalyst of hydrogen addition device 21h, catalyst of dehydrogenation device 21j). That is, the heat of the hot water obtained by the solar water heater 20 is used to release the hydrogen stored in the hydrogen tank 21d. Further, the heat of the hot water obtained by the solar water heater 20 is used to heat the catalyst in at least one of the hydrogenation unit 21h and the dehydrogenation unit 21j. The transfer of heat obtained by the solar water heater 200 to the hydrogen tank 21d and the like will be described in detail later.

[0223] This makes it possible to reduce the energy consumption of other heating devices such as the heat retention and cooling section 21c, compared to a configuration in which the heat of the hot water obtained by the solar water heater 20 is not used.

[0224] (Timing of heat supply) When the power supplied from the DC power generation device (solar power generation device) 11a of the first power generation device 11 is less than the power threshold Thp, it is desirable that the heat generated mainly during power generation by the second power generation device 12 be used to release the hydrogen stored in the hydrogen tank 21d. When the power supplied from the DC power generation device (solar power generation device) 11a of the first power generation device 11 is greater than or equal to the power threshold Thp, it is desirable to use the heat of the hot water obtained mainly by the solar water heater 20 to release the hydrogen stored in the hydrogen tank 21d.

[0225] As a result, during the time periods when hot water can be generated using the solar water heater 20, the hot water obtained by the solar water heater 20 is utilized as much as possible without using the second power generation device 12, thereby reducing the load on the second power generation device 12 and preserving the hydrogen stored in the liquid tank 21i.

[0226] (Example of heat source application) The supply of heat to components requiring heating in the first power / hydrogen supply station 10a (hydrogen tank 21d, catalyst of hydrogen addition device 21h, catalyst of dehydrogenation device 21j) is not limited to using hot water obtained by the solar water heater 20. For example, at least one of the heat generated during power generation in the second power generation unit 12, the heat generated during the hydrogenation reaction in the hydrogenation unit 21h, and the heat obtained in the heat exchange unit 130 may be utilized. In this case, the hydrogen stored in the hydrogen tank 21d is released using at least one of the heat generated during power generation by the second power generation device 12, the heat of the hot water obtained by the solar water heater 20, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained by the heat exchange section 130. The transfer of heat generated during power generation by the second power generator 12 to the hydrogen tank 21d and other components will be described in detail below.

[0227] (Example of application of heat-utilizing components) Furthermore, heat generated during power generation by the second power generator 12 may be used to heat the catalyst in at least one of the hydrogenation device 21h and the dehydrogenation device 21j.

[0228] (Example of heat transfer structure) We will explain the configuration in which the heat generated during power generation by the second power generation device 12, the heat obtained by the solar water heater 20, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained by the heat exchange section 130 are supplied to the hydrogen generation device 21b, etc. (see Figure 13).

[0229] The second heat medium (hot water) heated by the heat generated during power generation in the second power generation device 12, the heat obtained in the solar water heater 20, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained in the heat exchange section 130 is supplied to the hydrogen generation device 21b, etc. via the circulation path 200.

[0230] (Circulation route 200) The circulation path 200 is provided with a pump 210 and first to eighth valves 221 to 228. To supply the second heat medium, the circulation path 200 communicates with an electrolyte supply unit 21a. The pump 210 and the first to eighth valves 221 to 228 function as a flow rate control device (second flow rate control device) for the circulation path 200. However, the second flow rate control device may be configured with other members.

[0231] (Pump 210) The pump 210 circulates the hot water inside the circulation path 200 .

[0232] (First valve 221) The first valve 221 is provided between the solar water heater 20 and the circulation path 200 . The first valve 221 controls at least one of the supply of the second heat medium to the solar water heater 200 and the discharge of the second heat medium from the solar water heater 200. When the solar water heater 20 generates hot water, such as during the day, the first valve 221 is opened, and when the solar water heater 20 does not generate hot water, such as during the night, the first valve 221 is closed.

[0233] (Second valve 222) The second valve 222 is provided between the second power generating unit 12 and the circulation path 200 . The second valve 222 controls the passage of the second heat medium to the vicinity of the region in the second power generation unit 12 where heat is generated. When the second power generating device 12 is generating power, the second valve 222 is opened, and when the second power generating device 12 is not generating power, the second valve 222 is closed. Water discharged during power generation in the second power generation device 12 is supplied to the electrolyte solution supply unit 21a. The discharged water may be supplied to the electrolyte solution supply unit 21a via the circulation path 200 or via a separate flow path (see the dashed arrow in FIG. 13).

[0234] (Third valve 223) The third valve 223 is provided between the hydrogen addition device 21 h and the circulation path 200 . The third valve 223 controls the passage of the second heat medium to the vicinity of the region where heat is generated in the hydrogen addition apparatus 21h. When the hydrogenation device 21h is performing a hydrogenation reaction, the third valve 223 is opened, and when the hydrogenation reaction is not being performed, the third valve 223 is closed.

[0235] (4th valve 224) The fourth valve 224 is provided between the hydrogen addition device 21 h and the circulation path 200 . The fourth valve 224 controls the passage of the second heat medium near the first catalyst 21h1 in order to warm the first catalyst 21h1 in the hydrogen addition device 21h. Before the hydrogenation reaction in the hydrogenation device 21h is activated, when the second heat medium in the circulation path 200 is at a predetermined temperature or higher, the fourth valve 224 is opened, and at other times the fourth valve 224 is closed. However, while the hydrogenation reaction is taking place, it is highly likely that the catalyst in the hydrogenation device 21h is also at a high temperature, so the fourth valve 224 may be opened.

[0236] (5th valve 225) The fifth valve 225 is provided between the heat exchange section 130 and the circulation path 200 . The fifth valve 225 is a pipe through which the first heat medium passes from the liquid tank 110 in the heat exchange unit 130, and controls the passage of the second heat medium to a region that contacts the portion before cooling by the spray unit 130b. When the server 100 is running, the fifth valve 225 is in an open state, and when the server 100 is not running, the fifth valve 225 is in a closed state. The second heat transfer medium also functions as a coolant for the first heat transfer medium.

[0237] (6th valve 226) The sixth valve 226 is provided between the dehydrogenation device 21 j and the circulation path 200 .

The seventh valve 227 controls the passage of the second heat medium near the hydrogen tank 21d in order to heat the hydrogen tank 21d. When hydrogen stored in the hydrogen tank 21d is to be released, the seventh valve 227 is opened, and when hydrogen stored in the hydrogen tank 21d is not to be released, the seventh valve 227 is closed.

[0239] (8th valve 228) The eighth valve 228 is provided between the hydrogen generator 21b and the circulation path 200. The eighth valve 228 controls the supply of the second heat medium to the hydrogen generation device 21b in order to supply the second heat medium to the hydrogen generation device 21b. When hydrogen is generated in the hydrogen generator 21b, the eighth valve 228 is opened, and when hydrogen is not generated in the hydrogen generator 21b, the eighth valve 228 is closed. Moisture contained in the gas (such as drain water) from hydrogen generator 21b, hydrogen tank 21d, communicating pipe 21e, etc. is supplied to electrolyte solution supply unit 21a. The moisture contained in the gas may be supplied to electrolyte solution supply unit 21a via circulation path 200 or via a separate flow path (see dashed arrow in FIG. 13).

[0240] (Subject of motion control) The operation control of the pump 210 and the opening and closing control of the first valve 221 to the eighth valve 228 are performed by the control device 13 in accordance with the operating state of the station side operating unit 16.

[0241] In addition, a heat transfer device (e.g., a Peltier element) that transfers heat to the circulation path 200 by electrical control when necessary may be provided between a heat-generating device such as the second power generation device 12 and the circulation path 200. Furthermore, a heat transfer device may be provided between the circulation path 200 and a device that receives heat, such as the hydrogen tank 21d, and the circulation path 200, which transfers heat from the circulation path 200 by electrical control when necessary. Furthermore, only a heat transfer device may be provided between a heat generating device such as the second power generating device 12 and a heat receiving device such as the hydrogen tank 21d, without providing the circulation path 200.

[0242] FIG. 14 shows an example in which heat transfer devices (first heat transfer device 231 to sixth heat transfer device 236) are provided instead of second valve 222 to seventh valve 227. In FIG. The first heat transfer device 231 is provided between the region where heat is generated in the second power generation device 12 and the circulation path 200 .

The sixth heat transfer device 236 is provided between the hydrogen tank 21 d and the circulation path 200 .

[0243] (Example of application using auxiliary power supply) In the fourth embodiment, power is supplied from the first power storage unit 17a or the second power storage unit 17b to the electrical devices constituting the first power / hydrogen supply station 10a, such as the control device 13, the water intake unit 21a1, the flow rate control devices of the communicating pipe 21e (such as the eleventh valve b1 of the communicating pipe 21e), and the flow rate control devices of the circulation path 200 (such as the pump 210 and the first valve 221). However, a third power storage unit 17c may be provided in addition to the first power storage unit 17a and the second power storage unit 17b (see FIG. 15).

[0244] The third power storage unit 17c serves as an auxiliary power source and supplies power to the electrical equipment that constitutes the first power / hydrogen supply station 10a. In this case, the switching unit 22 has a first switching unit 22a, a second switching unit 22b, and a third switching unit 22c. The third switching unit 22c switches the destination of the power supply from the DC power generation device 11a between the third power storage unit 17c and the fifth conversion unit 13a5 (or the second power storage unit 17b).

[0245] The power obtained by DC power generation device 11a is supplied to third power storage unit 17c via first conversion unit 13a1, first switching unit 22a, and third switching unit 22c. However, power may be supplied to third power storage unit 17c from either first power storage unit 17a or second power storage unit 17b. Furthermore, although the connection is not shown in FIG. 15 , power obtained by AC power generation device 11b or power from an external power source connected to input terminal unit 24a may be supplied to third power storage unit 17c.

[0246] The charge capacity of the power storage device of second power storage unit 17b is larger than the charge capacity of the power storage device of third power storage unit 17c. For example, a lithium ion battery with a voltage of 48V and an amount of power (storage capacity): 15kWh is used as first power storage unit 17a, a lithium ion battery with a voltage of 48V and an amount of power (storage capacity): 10kWh is used as second power storage unit 17b, and a lithium ion battery with a voltage of 48V and an amount of power (storage capacity): 4.8kWh is used as third power storage unit 17c.

[0247] (Example of power output application) In the fourth embodiment, when power from DC power generator 11a is output from second output terminal 24b2, the power from DC power generator 11a is temporarily stored in second power storage unit 17b and then output from second output terminal 24b2. However, as shown in Fig. 15, the power from DC power generator 11a may be output via first conversion unit 13a1, first switching unit 22a, third switching unit 22c, fifth conversion unit 13a5, and second output terminal 24b2 without passing through second power storage unit 17b.

[0248] Furthermore, when power from AC power generation device 11b is output from second output terminal 24b2, the power from AC power generation device 11b is temporarily stored in second power storage unit 17b and then output from second output terminal 24b2. However, as shown in Fig. 15, the power from AC power generation device 11b may be output via second conversion unit 13a2, second switching unit 22b, fifth conversion unit 13a5, and second output terminal 24b2 without passing through second power storage unit 17b.

[0249] (two enclosures) The components constituting the first power / hydrogen supply station 10a may be housed in one housing (building 25) or two housings (first housing 25a and second housing 25b). For example, the first housing 25a includes the DC power generator 11a, the AC power generator 11b, and the first power storage unit 17a (the area above and to the right of the dotted line in FIG. 15). The second housing 25b includes the second power generator 12, the second power storage unit 17b, the third power storage unit 17c, the solar water heater 20, and the hydrogen storage unit 21.

[0250] (Effect of supplying power to the first flow rate control device (such as the eleventh valve b1 of the communicating pipe 21e) from an auxiliary power source (the third power storage unit 17c) separate from the fuel cell power storage unit (the second power storage unit 17b)) The auxiliary power supply (third power storage unit 17c) operates the inside of the power supply station (first power / hydrogen supply station 10a), and the auxiliary power supply can be used as a start-up power supply for supplying hydrogen to the fuel cell, which means that the power obtained from hydrogen can be efficiently stored.

[0251] (Effects of using the renewable energy-derived power generation device (first power generation device 11)) Using solar power generation and other renewable energy-based power generation equipment, it will be possible to convert surplus electricity into hydrogen and store it. Storing hydrogen is easier to store energy in a smaller volume than storing electricity, and there is less degradation over long periods of storage.

[0252] (Effect of using water obtained from a fuel cell (second power generating device 12) etc. as an electrolyte) By utilizing the water generated in the second power generating device 12 and the hydrogen storage unit 21 as the electrolyte, hydrogen can be generated even when there is little water supplied from the outside.

[0253] (Effect of supplying power to the second flow rate control device (pump 210 of circulation path 200, etc.) from an auxiliary power supply (third power storage unit 17c) separate from the fuel cell power storage unit (second power storage unit 17b)) The auxiliary power supply (third power storage unit 17c) operates the inside of the power supply station (first power / hydrogen supply station 10a), and the auxiliary power supply can be used as a start-up power source for supplying water to a solar water heater 20, etc.

[0254] (Application example of the first power / hydrogen supply station 10a, fifth embodiment) The first power / hydrogen supply station 10a of the fourth embodiment can be applied to a charging / power supply station for an electrically powered mobile device such as a first electric vehicle c1 (fifth embodiment, see FIG. 16). The following will mainly explain the differences from the fourth embodiment. The switching unit 22 of the first power / hydrogen supply station 10a of the fifth embodiment further includes a fourth switching unit 22d between the third conversion unit 13a3 and the first power storage unit 17a. In the fifth embodiment, as shown in FIG. 16, the solar water heater 20, the first output terminal portion 24b1, etc. may be omitted.

[0255] Furthermore, the third power storage unit 17c may be omitted. In this case, the first power storage unit 17a or the second power storage unit 17b functions as an auxiliary power supply. In the fifth embodiment, the first power storage unit 17a functions as an auxiliary power supply and supplies power to the electrical devices constituting the first power / hydrogen supply station 10a, such as the control device 13.

[0256] In addition, the second power generation device 12 and the hydrogen storage unit 21 may also be omitted. When the hydrogen storage unit 21 is omitted, the first power / hydrogen supply station 10a does not have the function of supplying hydrogen to the outside or inside, and functions as a power supply station.

[0257] (Storage capacity of first power storage unit 17a and second power storage unit 17b) In the fifth embodiment, the charge capacity of the power storage device of first power storage unit 17a is smaller than the charge capacity of the power storage device of second power storage unit 17b. For example, a lithium ion battery with a voltage of 48V and an amount of electric power (electric power storage capacity): 10kWh is used as first power storage unit 17a, and a lithium ion battery with a voltage of 48V and an amount of electric power (electric power storage capacity): 120kWh is used as second power storage unit 17b.

[0258] (1st load 19a~4th load 19d) In the fifth embodiment, the first power storage unit 17a supplies power to the first to fourth loads 19a to 19d. The first load 19a to the fourth load 19d of the fifth embodiment are electrical devices of the first power / hydrogen supply station 10a. The first load 19a includes a lighting device that illuminates the surroundings of the first power / hydrogen supply station 10a. The second load 19b includes an imaging device that acquires image information of the surrounding area. The third load 19c includes a lock control device for a luggage storage area 29 (such as a delivery box) and a temperature control device for cooling or heating the luggage storage area, both of which are provided in the first power / hydrogen supply station 10a. Fourth load 19d includes a display device (such as station-side display unit 15) that outputs information relating to the charging status of first power storage unit 17a and second power storage unit 17b.

[0259] (Fourth switching unit 22d) Fourth switch unit 22d switches the destination of power supply from input terminal unit 24a between first power storage unit 17a and second power storage unit 17b.

[0260] (input terminal section 24a) The input terminal unit 24a of the fifth embodiment is detachably connected to an external power source (for example, a commercial power source or the first electric vehicle c1). Electric power from an external power supply connected to input terminal unit 24a is supplied to first power storage unit 17a or second power storage unit 17b via input terminal unit 24a and third conversion unit 13a3.

[0261] (Switching control of the first switching unit 22a, the second switching unit 22b, and the fourth switching unit 22d) Normally, the control device 13 controls the first switching unit 22a and the second switching unit 22b so that the power from the DC power generation device 11a and the AC power generation device 11b is supplied to the first power storage unit 17a. When the charging rate R1a of the first power storage unit 17a is higher than or equal to the full charge threshold Thrf and the power P supplied from the first power generation device 11 (DC power generation device 11a, AC power generation device 11b) is higher than or equal to the power threshold Thp, it is determined that surplus power is being generated, and the control device 13 controls the first switching unit 22a and the second switching unit 22b so that power from the DC power generation device 11a and the AC power generation device 11b is supplied to the second power storage unit 17b.

[0262] The power from the commercial power supply is mainly supplied to first power storage unit 17a. When a commercial power supply is connected to input terminal unit 24a, control device 13 controls fourth switch unit 22d so that power from the commercial power supply is supplied to first power storage unit 17a. However, when the charging rate R1a of the first power storage unit 17a is higher than or equal to the full charge threshold Thrf, it is determined that surplus power is being generated, and the control device 13 controls the fourth switching unit 22d so that power from the commercial power source is supplied to the second power storage unit 17b.

[0263] Electric power from the electric vehicle is mainly supplied to second power storage unit 17b. When the power supply terminal of the first electric vehicle c1 is connected to the input terminal unit 24a, the control device 13 controls the fourth switching unit 22d so that power from the first electric vehicle c1 is supplied to the second power storage unit 17b. However, when the charging rate R1b of the second power storage unit 17b is higher than or equal to the full charge threshold Thrf, it is determined that surplus power is being generated, and the control device 13 controls the fourth switching unit 22d so that power from the first electric vehicle c1 is supplied to the first power storage unit 17a.

[0264] The determination as to whether the input terminal section 24a is connected to a commercial power source or to the power supply terminal of the first electric vehicle c1 is automatically made by the control device 13 or the like. The control device 13 makes this determination based on information from a detection unit 13c provided around the input terminal unit 24a. The detection unit 13c detects the voltage value or current value of the power supplied to the input terminal unit 24a, or captures an image of the area around the device connected to the input terminal unit 24a.

[0265] Alternatively, the input terminal unit 24a for connecting to a commercial power source and the input terminal unit 24a for connecting to a power supply unit of the electric vehicle may be provided separately. In this case, the third conversion unit 13a3 for AC / DC conversion of power from the commercial power source and the third conversion unit 13a3 for AC / DC conversion of power from the power supply unit of the electric vehicle are provided separately. Furthermore, the fourth switching unit 22d is omitted.

[0266] The first power and hydrogen supply station 10a of the fifth embodiment has been described as being fixed to the ground as a charging and power supply stand. However, the first power and hydrogen supply station 10a may be provided with a mobile unit 50 (see FIG. 17). The mobile unit 50 moves the housing 25 that holds each component of the first power and hydrogen supply station 10a between at least one of land, water, underwater, and air. During movement by the movement unit 50, power may be supplied from the second power storage unit 17b to the electric movement device c5 connected to the second output terminal unit 24b2. The electric vehicle c5 may be an electric vehicle, a ship that can move by electricity, an airplane, or the like. The moving unit 50 is driven by power from the second power storage unit 17b or the first power storage unit 17a.

[0267] (Effects of power supply from and charging of electric mobility devices) It is possible to supply power from the electric vehicle c5 (such as the first electric vehicle c1) via the input terminal 24a and to charge the electric vehicle c5 via the second output terminal 24b2, making it possible to use the first power / hydrogen supply station 10a as a charging / power supply station for the electric vehicle c5. The first power storage unit 17a can be used to drive loads inside the first power / hydrogen supply station 10a, and the second power storage unit 17b can be used to charge the electric vehicle c5 or to supply power from the electric vehicle c5.

[0268] (The effect of providing a luggage storage area at charging / power stations) The luggage storage area 29 of the charging / power supply station (first power / hydrogen supply station 10a) can be used as a delivery locker. In addition, the first power storage unit 17a drives the lock control device (third load 19c) of the luggage storage area 29, making it possible to operate the charging / power supply station and the delivery locker without relying on an external power supply.

[0269] (The effect of having a mobile power and hydrogen supply station) After moving to a predetermined location by the moving unit 50, or while moving by the moving unit 50, it becomes possible to supply power from the second storage unit 17b to the electric moving device c5 connected to the second output terminal unit 24b2.

[0270] (Example of application of power supply to hydrogen generation device 21b) In the second to fifth embodiments, an example has been described in which power is supplied to the hydrogen generation device 21b from the first power storage unit 17a. However, power may be supplied to the hydrogen generation device 21b directly from the first power generation device 11 or an external power source connected to the input terminal unit 24a, without going through the first power storage unit 17a. In this case, the hydrogen generation device 21b performs electrolysis of the electrolyte based on power from at least one of the first power generation device 11, the first power storage unit 17a, and the external power source.

[0271] (Example of application where external hydrogen supply is omitted) In the first to fifth embodiments, the hydrogen generated by the hydrogen generation device 21b is supplied to the outside via the hydrogen supply unit 21g, but the hydrogen may be used only to supply to the second power generation device 12. In this case, the hydrogen supply unit 21g is omitted, and the first power / hydrogen supply station 10a does not have the function of supplying hydrogen to the outside, but functions as a power supply station.

[0272] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are intended to be included within the scope and spirit of the invention, as well as within the scope of the invention described in the claims and their equivalents.
