[0002] Conventionally, a power generation device that generates electricity using hydrogen generated in a hydrogen generation container is known (for example, Patent Document 1). The power generation device described in Patent Document 1 includes a hydrogen generation container in which a stock solution such as water is poured to generate hydrogen, and a generator that generates electricity using the hydrogen generated in the hydrogen generation container.

[0003] [Patent Document 1] JP 2017-226577 A Summary of the Invention [Problem to be solved by the invention]

[0004] In order to generate a large amount of hydrogen, it is possible to increase the capacity of the hydrogen generating container itself. However, if the capacity of each hydrogen generating container is large, the transportability of the hydrogen generating container is impaired. Therefore, while a hydrogen generating container with a large capacity can generate a large amount of hydrogen, there is a risk that the ease of replacement work in the power generation device will be reduced.

[0005] The present invention has been made in consideration of these points, and aims to provide a power generation device and a fuel cell device that are capable of generating a large amount of hydrogen without increasing the container capacity per hydrogen generation container. [Means for solving the problem]

[0006] One aspect of the present invention is a power generation device comprising a hydrogen generation container formed in a container-like shape having an inlet through which a stock solution is injected and an outlet through which hydrogen is discharged, a generator that generates electricity using the hydrogen generated in the hydrogen generation container, a case body that houses the hydrogen generation container and the generator, a tray section on which a plurality of hydrogen generation containers can be mounted, and a movement mechanism that moves the tray section relative to the case body between a stored position inside the case body and an exposed position outside the case body.

[0007] According to this configuration, a large amount of hydrogen can be generated without increasing the capacity of each hydrogen generating container. [Brief description of the drawings]

[0009] Specific embodiments of a power generating device and a fuel cell device according to the present invention will be described below with reference to FIGS. 1 to 5. FIG.

[0010] A fuel cell device 1 according to one embodiment is a device that generates hydrogen, generates electricity using the generated hydrogen, stores the generated electrical energy, and outputs the electrical energy to the outside. The fuel cell device 1 is installed in a location where electrical energy is used (for example, a house, a factory, a building, a vehicle, etc.). The fuel cell device 1 includes a power generation device 2 including a hydrogen generation container 10 and a generator 20.

[0011] As shown in Figures 1 and 2, the fuel cell device 1 includes a hydrogen generation container 10, a generator 20, a battery device 30, a case main body 40, a tray section 41, a moving mechanism 42, an output terminal section 50, a concentrate tank 60, a concentrate inlet passage 61, a concentrate supply pump 62, a hydrogen storage device 70, a switching section 80, and a control device 90.

[0012] The hydrogen generating container 10 is a container that generates hydrogen. As shown in FIG. 3, the hydrogen generating container 10 is formed in a container shape. The hydrogen generating container 10 is composed of, for example, a tube portion (for example, a cylindrical or rectangular tube portion) and a dome portion that closes the upper end of the tube portion. The hydrogen generating container 10 has an inlet 11. A stock solution is injected into the hydrogen generating container 10 through the inlet 11. The hydrogen generating container 10 may be provided with a safety valve that releases hydrogen gas when the pressure inside the container exceeds a certain pressure. The hydrogen generating container 10 is preferably formed in a size that allows easy transportation by a person. For example, the hydrogen generating container 10 is formed in a size of Φ160 mm×500 mm.

[0013] The stock solution tank 60 is a tank that stores the stock solution to be injected into the hydrogen generation container 10. The stock solution tank 60 and the hydrogen generation container 10 are connected via a stock solution inlet passage 61. The stock solution in the stock solution tank 60 is introduced into the hydrogen generation container 10 via the stock solution inlet passage 61.

[0014] The stock solution supply pump 62 is a pump that supplies the stock solution in the stock solution tank 60 toward the inlet 11 of the hydrogen generation container 10. The stock solution supply pump 62 is disposed on the stock solution introduction path 61. The operation of the stock solution supply pump 62 is controlled according to commands from the control device 90 as described below, and supplies the stock solution in the stock solution tank 60 toward the inlet 11 by this operation. The stock solution supplied to the inlet 11 is injected into the hydrogen generation container 10 from the inlet 11.

[0015] A reactant is stored in the hydrogen generation container 10. In the hydrogen generation container 10, a hydrogen generation reaction occurs in which the stored reactant reacts with the stock solution injected from the injection port 11, generating hydrogen gas. The stock solution and reactant may be any that generate hydrogen by utilizing the electrolysis of water. For example, the stock solution is water, and the reactant is calcium hydroxide, aluminum, magnesium, or the like. The hydrogen generation container 10 has an outlet 12. Hydrogen generated in the hydrogen generation container 10 is discharged from the hydrogen generation container 10 via the outlet 12.

[0016] The generator 20 is a fuel cell that generates electricity using hydrogen generated in the hydrogen generation container 10. The hydrogen generation container 10 and the generator 20 are connected via a hydrogen discharge path 15. The hydrogen generated in the hydrogen generation container 10 is led to the generator 20 via the hydrogen discharge path 15. The generator 20 utilizes the principle of water electrolysis to chemically react the hydrogen generated in the hydrogen generation container 10 with oxygen in the air to generate electrical energy.

[0017] A first hydrogen discharge pump 16 is disposed on the hydrogen discharge path 15. The first hydrogen discharge pump 16 is a pump that supplies hydrogen gas in the hydrogen generation container 10 toward the generator 20. The operation of the first hydrogen discharge pump 16 is controlled according to commands from a control device 90 as described below, and supplies hydrogen gas in the hydrogen generation container 10 toward the generator 20 through this operation. The hydrogen gas supplied to the generator 20 chemically reacts with oxygen in the generator 20.

[0018] The hydrogen storage device 70 is a container for storing hydrogen generated in the hydrogen generation container 10. The hydrogen storage device 70 is formed in a container shape. The hydrogen storage device 70 is composed of, for example, a tube portion (for example, a cylindrical or rectangular tube portion) and a dome portion that closes the upper end of the tube portion. The hydrogen storage device 70 has an inlet 71 that connects to a first branched passage 17 that branches off from the hydrogen discharge passage 15. The hydrogen storage device 70 stores hydrogen gas supplied from the hydrogen discharge passage 15 via the first branched passage 17 and the inlet 71. The hydrogen storage device 70 may incorporate, for example, a powdered or pelleted hydrogen storage material. The hydrogen storage device 70 may be provided with a safety valve that releases hydrogen gas when the pressure inside the container exceeds a certain pressure.

[0019] The switching unit 80 is a changeover switch or a changeover valve that switches between a state in which hydrogen generated in the hydrogen generation container 10 flows to the generator 20 side and a state in which hydrogen flows to the hydrogen storage container 70 side (i.e., the first branch line 17). The switching unit 80 is disposed on the hydrogen discharge line 15, and more specifically, is disposed downstream of the first hydrogen discharge pump 16. The switching unit 80 performs the above-mentioned switching in accordance with a command from the control device 90, as described below.

[0020] The hydrogen storage device 70 has an outlet 72, one end of which connects to the lower end of a second branched path 18 that connects to the hydrogen discharge path 15 downstream of the switching unit 80. A second hydrogen discharge pump 19 is disposed on the second branched path 18. The second hydrogen discharge pump 19 is a pump that supplies hydrogen gas in the hydrogen storage device 70 toward the generator 20. The operation of the second hydrogen discharge pump 19 is controlled in accordance with commands from a control device 90, as described below, and supplies hydrogen gas in the hydrogen storage device 70 toward the generator 20 as a result of this operation.

[0021] The generator 20 is a DC generator that outputs the generated electric energy at a DC voltage (for example, about DC 24 volts). The generator 20 supplies the output electric energy to the battery device 30.

[0022] The battery device 30 is a device that stores the electric energy generated by the generator 20. The battery device 30 has a battery main body 31, a charger 32, and a converter 33. The battery main body 31 is a secondary battery that is charged by the electric energy generated by the generator 20.

[0023] The charger 32 is a device that charges the battery main body 31, and supplies the electric energy generated by the generator 20 to the battery main body 31 at a predetermined DC voltage (for example, about DC 24 volts). The charger 32 is interposed between the generator 20 and the battery main body 31.

[0024] The converter 33 is a device that performs voltage conversion when extracting the electric energy stored in the battery main body 31. The converter 33 is disposed on the output side of the battery main body 31. The converter 33 converts the DC voltage output by the battery main body 31 to a predetermined voltage (e.g., AC 100 volts) and outputs it. The maximum current output by the converter 33 may be, for example, 20 amperes or more.

[0025] The hydrogen generation container 10, the generator 20, and the battery device 30 are housed in a case body 40. The stock solution tank 60, the stock solution inlet path 61, the stock solution supply pump 62, the hydrogen storage device 70, the switching unit 80, the control device 90, the hydrogen discharge pumps 16, 19, the hydrogen discharge path 15, the first branch path 17, and the second branch path 18 are also housed in the case body 40. The case body 40 is formed, for example, in a rectangular parallelepiped shape, with a vertical height of 700 mm to 1 m and a front-to-back, left-to-right side of 400 mm to 500 mm.

[0026] The case body 40 may be configured to divide the internal space into a plurality of chambers. Although the battery device 30 (particularly the battery body 31) is relatively heavy, it is preferable to store it in the lower chamber of the internal space of the case body 40 in order to ensure the installation stability of the fuel cell device 1.

[0027] The tray portion 41 is a member capable of mounting a plurality of hydrogen generation containers 10. Each hydrogen generation container 10 is detachable from the tray portion in a cartridge format. The tray portion 41 may further be capable of mounting a hydrogen storage device 70. The tray portion 41 is formed in a plate shape. The tray portion 41 is movable in the horizontal direction relative to the case body 40. The tray portion 41 can move between a storage position where it is stored inside the case body 40 and an exposed position where it is exposed outside the case body 40.

[0028] An opening 45 is provided in the case body 40. The opening 45 is provided on one of the side surfaces of the case body 40. The opening 45 is formed to a size such that the tray portion 41 and the hydrogen generation container 10 do not interfere with the case body 40 when the tray portion moves between the above-mentioned storage position and exposed position with the hydrogen generation container 10 placed on the tray portion 41. The opening 45 can be closed by an opening / closing door 46. The opening / closing door 46 is supported by the case body 40 so as to be capable of opening and closing operations. The tray portion 41 can move between the above-mentioned storage position and exposed position with the opening / closing door 46 opening the opening 45.

[0029] The moving mechanism 42 is a mechanism for moving the tray section 41 between the above-mentioned stored position and exposed position. The moving mechanism 42 is composed of, for example, a pair of slide rails. The moving mechanism 42 causes the tray section 41 to slide relative to the case body 40 by a rail attached and fixed to the mounting upper surface of the case body 40 and a rail attached and fixed to the bottom back surface of the tray section 41 slidably engaging with each other.

[0030] The above-mentioned stock solution introduction passage 61 has an upstream introduction passage 61a and a downstream introduction passage 61b. The upstream introduction passage 61a is provided on the stock solution tank 60 side, and the downstream introduction passage 61b is provided on the hydrogen generation container 10 side. The upstream introduction passage 61a is a single passage, and is connected to the stock solution tank 60 at its upstream end. The downstream introduction passage 61b is a branch passage branched into multiple passages from the downstream end of the upstream introduction passage 61a. The multiple downstream introduction passages 61b are connected to each other at their upstream ends and connected to the downstream end of the upstream introduction passage 61a. Each downstream introduction passage 61b is connected to the injection port 11 of each hydrogen generation container 10 at its downstream end.

[0031] The above-mentioned stock solution supply pump 62 is disposed on the upstream inlet 61a. The downstream inlet 61b and each hydrogen generating container 10 are connected to each other via an inlet connector 61c that facilitates attachment and detachment of the two. Each of the multiple inlet connectors 61c is disposed at the downstream end of the downstream inlet 61b and is detachable from the inlet 11 of the corresponding hydrogen generating container 10. The inlet connector 61c may be configured to include a first inlet connector disposed at the downstream end of the downstream inlet 61b and a second inlet connector disposed at the inlet 11 of the hydrogen generating container 10, and the first and second connectors may be configured to be switched between engaged and unengaged. This inlet connector 61c can improve the workability when replacing the hydrogen generating container 10.

[0032] The hydrogen discharge passage 15 has an upstream discharge passage 15a and a downstream discharge passage 15b. The upstream discharge passage 15a is provided on the hydrogen generation container 10 side, and the downstream discharge passage 15b is provided on the generator 20 side. A plurality of upstream discharge passages 15a are provided. Each upstream discharge passage 15a is connected to the discharge port 12 of each hydrogen generation container 10 at its upstream end. The plurality of upstream discharge passages 15a are connected to each other at their downstream ends, and are connected to the upstream end of the downstream discharge passage 15b at their downstream ends. The downstream discharge passage 15b is a single passage, and is connected to the generator 20 at its downstream end.

[0033] The first hydrogen discharge pump 16 and the switching unit 80 are disposed on the downstream discharge passage 15b. The upstream discharge passage 15a and each hydrogen generation container 10 are connected to each other via discharge connectors 15c that facilitate attachment and detachment of the upstream discharge passage 15a and the hydrogen generation container 10. Each of the multiple discharge connectors 15c is disposed at the upstream end of the upstream discharge passage 15a and is detachable from the outlet 12 of the corresponding hydrogen generation container 10. The discharge connector 15c may be configured to include a first discharge connector disposed at the upstream end of the upstream discharge passage 15a and a second discharge connector disposed at the outlet 12 of the hydrogen generation container 10, and the first and second discharge connectors may be configured to be switched between engaged and unengaged. This discharge connector 15c can improve the workability when replacing the hydrogen generation container 10.

[0034] The output terminal unit 50 is a portion that outputs the electric energy stored in the battery main body 31 of the battery device 30 to the outside of the case main body 40. The output terminal unit 50 is provided so as to be exposed to the outside of the case main body 40. The output terminal unit 50 is connected to the output side of the converter 33. The output terminal unit 50 outputs the electric energy to the outside of the case main body 40 at the output voltage (e.g., AC 100 volts) converted by the converter 33. An electric appliance, a home appliance, or the like is electrically connected to the output terminal unit 50.

[0035] The control device 90 is a device that controls the operation of the concentrate supply pump 62, first hydrogen discharge pump 16, and second hydrogen discharge pump 19 based on the remaining amount of hydrogen stored in the hydrogen storage device 70 and the remaining amount of electrical energy stored in the battery body 31 of the battery device 30, and also performs switching at the switching unit 80. The control device 90 has a control unit 91, a first sensor 92, and a second sensor 93. The control unit 91 is installed in the case body 40, for example, in the upper chamber.

[0036] The control unit 91 is a control unit mainly composed of a microcomputer. The first sensor 92 is a part that outputs an electric signal according to the remaining amount of hydrogen stored in the hydrogen storage device 70. The second sensor 93 is a part that outputs an electric signal according to the remaining amount of electric energy stored in the battery main body 31. The control unit 91 performs the various controls described above based on the output signals of the first sensor 92 and the second sensor 93.

[0037] Next, the operation of the fuel cell device 1 will be described with reference to FIGS. The control unit 91 determines whether the remaining amount of hydrogen stored in the hydrogen storage device 70 is equal to or less than a first remaining amount based on the output signal of the first sensor 92 (step 100 in the routine shown in FIG. 4). The first remaining amount is, for example, 20% of the maximum storage amount of hydrogen in the hydrogen storage device 70.

[0038] Then, when the control unit 91 determines that the hydrogen storage remaining amount is equal to or less than the first remaining amount, it turns on the operation of the raw solution supply pump 62 and turns on the operation of the first hydrogen discharge pump 16 (step 110). In this case, the raw solution is sucked out of the raw solution tank 60 by turning on the raw solution supply pump 62, and the raw solution is injected into each hydrogen generation container 10 via the downstream inlet path 61b of the raw solution inlet path 61, and as a result, each hydrogen generation container 10 generates hydrogen. When the hydrogen generation container 10 is in a state where it generates hydrogen, hydrogen is sucked out of each hydrogen generation container 10 by turning on the first hydrogen discharge pump 16.

[0039] The hydrogen sucked by the first hydrogen discharge pump 16 is guided to the generator 20 via the hydrogen discharge path 15 when the switching unit 80 is in a state where it flows to the generator 20 side, and is guided to the hydrogen storage device 70 via the first branch path 17 when the switching unit 80 is in a state where it flows to the hydrogen storage device 70 side.

[0040] On the other hand, if the control unit 91 determines that the hydrogen storage remaining amount is not equal to or less than the first remaining amount, it then determines whether or not the hydrogen storage remaining amount has reached a second remaining amount (step 120). The second remaining amount is greater than the above-mentioned first remaining amount, and is, for example, 100% of the maximum storage amount of hydrogen in the hydrogen storage device 70.

[0041] If the control unit 91 determines that the hydrogen storage remaining amount has not reached the second remaining amount, it maintains the previous state. On the other hand, if it determines that the hydrogen storage remaining amount has reached the second remaining amount, it turns off the operation of the raw solution supply pump 62, turns off the operation of the first hydrogen discharge pump 16, and switches or maintains the switching unit 80 in a state in which hydrogen flows to the generator 20 side (step 130). In this case, the raw solution is not injected into the hydrogen generation container 10, so hydrogen is not generated. Note that the supply of raw solution by the raw solution supply pump 62 to the hydrogen generation container 10 may be stopped when a predetermined time (e.g., 2 to 3 seconds) has elapsed since the start of the supply, instead of being stopped when the condition that the hydrogen storage remaining amount reaches the second remaining amount is satisfied.

[0042] Furthermore, the control unit 91 determines whether or not the remaining amount of electric energy stored in the battery main body 31 has reached a third remaining amount based on the output signal of the second sensor 93 (step 200 in the routine shown in FIG. 5). The fourth remaining amount is greater than the above-mentioned third remaining amount, and is, for example, 100% of the maximum charge amount of the battery main body 31.

[0043] When the control unit 91 determines that the remaining amount of electric energy has reached the third remaining amount, it turns off the operation of the second hydrogen discharge pump 19 and switches or maintains the switching unit 80 in a state in which hydrogen flows to the hydrogen storage device 70 side (step 210). In this case, the supply of hydrogen in the hydrogen storage device 70 to the generator 20 is restricted.

[0044] On the other hand, when the control unit 91 determines that the remaining amount of electric energy has not reached the third remaining amount, it then determines whether or not the remaining amount of electric energy is equal to or less than a fourth remaining amount (step 220). Note that the fourth remaining amount is, for example, 50% of the maximum amount of electric energy in the battery main body 31.

[0045] If the control unit 91 determines that the remaining amount of electric energy is not equal to or less than the fourth remaining amount, it maintains the previous state. On the other hand, if the control unit 91 determines that the remaining amount of electric energy is equal to or less than the fourth remaining amount, it turns on the operation of the second hydrogen discharge pump 19 (step 230). In this case, hydrogen in the hydrogen storage device 70 is supplied to the generator 20 via the second branch path 18, which generates electricity and charges the battery main body 31.

[0046] 4 and 5, for example, when the battery main body 31 is sufficiently charged and the remaining amount of hydrogen stored in the hydrogen storage device 70 falls below a first remaining amount, hydrogen is generated in the hydrogen generation container 10 and, since the switching unit 80 is on the hydrogen storage device 70 side, the hydrogen is supplied to the hydrogen storage device 70 and the remaining amount of hydrogen stored increases. Then, when the remaining amount of hydrogen stored reaches a second remaining amount, hydrogen generation in the hydrogen generation container 10 is stopped and the switching unit 80 is switched to the generator 20 side.

[0047] Next, when the remaining amount of electric energy in the battery main body 31 decreases to a fourth remaining amount or less while the switching unit 80 is switched to the generator 20 side, hydrogen in the hydrogen storage device 70 is supplied to the generator 20 to charge the battery main body 31. Then, when the remaining amount of electric energy in the battery main body 31 reaches a third remaining amount, the discharge of hydrogen from the hydrogen storage device 70 is stopped. Note that, when the remaining amount of hydrogen storage in the hydrogen storage device 70 decreases to a first remaining amount or less before the remaining amount of electric energy in the battery main body 31 reaches the third remaining amount, hydrogen is generated in the hydrogen generation container 10 and, since the switching unit 80 is on the generator 20 side, the hydrogen generated in the hydrogen generation container 10 is directly supplied to the generator 20 via the hydrogen discharge path 15. Therefore, in this case, both the hydrogen generated in the hydrogen generation container 10 and the hydrogen in the hydrogen storage device 70 are supplied to the generator 20, and the generator 20 generates electricity and the battery main body 31 is charged.

[0048] In this embodiment, the hydrogen generation container 10, generator 20, battery device 30, etc. are housed in a case body 40, and multiple hydrogen generation containers 10 housed in the case body 40 can be mounted on a tray portion 41, and the tray portion 41 can be moved by a moving mechanism 42 between a stored position inside the case body 40 and an exposed position outside the case body 40.

[0049] According to this configuration, since power generation can be performed using a plurality of hydrogen generation containers 10 in the power generation device 2 and thus in the fuel cell device 1, a large amount of hydrogen can be generated without increasing the container capacity of each hydrogen generation container 10. If the container capacity of each hydrogen generation container 10 is not large, the transportability of the hydrogen generation container 10 is not impaired. Therefore, the ease of replacement of the hydrogen generation container 10 in the power generation device 2 and thus in the fuel cell device 1 can be ensured.

[0050] In this embodiment, the inlet 11 of the hydrogen generating container 10 to be replaced and the stock solution inlet 61 on the stock solution tank 60 side are detachably connected to each other via the inlet connector 61c. The outlet 12 of the hydrogen generating container 10 to be replaced and the hydrogen outlet 15 are detachably connected to each other via the outlet connector 15c. This improves the workability when replacing the hydrogen generating container 10 compared to a configuration in which the hydrogen generating container 10 and the stock solution inlet 61 or the hydrogen outlet 15 are fixed to each other by, for example, a bolt tightening operation and released from the fixed state by a bolt loosening operation. In particular, even if there are multiple hydrogen generating containers 10 to be replaced, the replacement work can be prevented from being prolonged.

[0051] In addition, multiple hydrogen generation containers 10 can be mounted on the tray portion 41 at the same time, and the multiple hydrogen generation containers 10 can be pulled out to an exposed position outside the case body 40 by moving the tray portion 41 by the moving mechanism 42. This makes it possible to easily replace the hydrogen generation containers 10 in the case body 40.

[0052] In the above embodiment, the hydrogen generation container 10, the generator 20, and the battery device 30 constituting the fuel cell device 1 including the power generation device 2 are accommodated in the case body 40. However, the present invention is not limited to this, and may be applied to an arrangement in which at least the hydrogen generation container 10 and the generator 20 constituting the power generation device 2 are accommodated in the case body 40.

[0053] 4 and 5 based on the output signal of the first sensor 92 and the output signal of the second sensor 93. However, the present invention is not limited to this, and the control unit 91 may also control the stock solution supply pump 62, the first hydrogen discharge pump 16, the second hydrogen discharge pump 19, and the switching unit 80 according to other routines.

[0054] The present invention is not limited to the above-mentioned embodiments and modifications, and various modifications can be made without departing from the spirit of the present invention. In addition, this specification discloses not only the technical ideas shown by the citation relationships described in each claim at the time of filing, but also the technical ideas obtained by appropriately combining the matters described in each claim.
