[Diagram 2] 13 is a diagram showing an example of a form of displaying information derived from hydrogen gas. [Diagram 3] 2 is a flowchart of the hydrogen gas origin information display system 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, a hydrogen gas origin information display system 1 according to one embodiment of the present invention will be described with reference to the accompanying drawings. In each drawing, corresponding components are given the same reference numerals, and duplicated explanations will be omitted.

[0016] First, a configuration example of a hydrogen gas origin information display system 1 according to the first embodiment will be described with reference to FIG.

[0017] FIG. 1 is a system configuration diagram of a hydrogen gas origin information display system 1. As shown in FIG.

[0018] 1, the hydrogen gas origin information display system 1 includes a fuel cell 10, a fuel tank 20, a hydrogen gas origin information display unit 30, a communication unit 40, a control unit 50, a memory unit 60, and a communication partner device 70. The fuel cell 10, the fuel tank 20, the hydrogen gas origin information display unit 30, the communication unit 40, the control unit 50, and the memory unit 60 are mounted on a vehicle V. The communication partner device 70 is installed in a hydrogen gas supply facility ST (e.g., a hydrogen station).

[0019] The vehicle V is, for example, a kitchen car or an office car. The kitchen car is, for example, a vehicle equipped with items used in a kitchen (for example, cooking utensils). The office car is, for example, a vehicle equipped with items used in an office (for example, a display). The type of the vehicle V is, for example, a minivan or a camper.

[0020] The fuel cell 10 is, for example, a solid polymer fuel cell. Although not shown, the fuel cell 10 includes a stack formed by stacking a plurality of single cells that generate electricity by electrochemically reacting hydrogen gas (hydrogen) and air (oxygen) supplied from a fuel tank 20 into one structural unit. As the fuel cell 10, for example, those described in JP 2018-41630 A and JP 2019-121578 A can be used. Although not shown, the power generated by the fuel cell 10 (stack) is supplied to the drive motor of the vehicle V, various auxiliary machines mounted on the vehicle V, and an outlet provided in the vehicle cabin. The outlet is a device into which plugs of electrical appliances (for example, a refrigerator / freezer, a water server, an electric rice cooker, an electric kettle, a television, a personal computer, a charger) are inserted to obtain electric power (AC power). The outlet is also called an outlet or a socket.

[0021] The hydrogen gas origin information display unit 30 is a display device having a display unit (e.g., a display surface) such as a liquid crystal display, and is provided in the passenger compartment of the vehicle V. The hydrogen gas origin information display unit 30 may be, for example, an indicator provided on an instrument panel.

[0022] The communication unit 40 is a communication device that performs wireless communication with a communication partner device 70 (communication unit 73).

[0023] The control unit 50 includes a processor (not shown). The processor is, for example, a CPU (Central Processing Unit). There may be one processor or multiple processors. The processor functions as a hydrogen gas origin information acquisition unit 51 and a display control unit 52 by executing a predetermined program loaded from a non-volatile storage unit 60 (program storage unit 61) such as a ROM to a RAM (not shown). Some or all of these may be realized by hardware.

[0024] The hydrogen gas origin information acquisition unit 51 acquires, via the communication unit 40, the hydrogen gas origin information wirelessly transmitted by the communication partner device 70 via the communication unit 73. The acquired hydrogen gas origin information is stored in the hydrogen gas origin information storage unit 62.

[0025] The hydrogen gas origin information is information that indicates the origin of the hydrogen gas filled in the fuel tank 20 (for example, information that indicates the "manufacturing method of hydrogen gas" and information that indicates the "environmental load").

[0026] There are, for example, four "hydrogen gas production methods." (1) The first hydrogen gas production method, in which hydrogen is obtained by reacting fossil fuels with steam. (2) The second hydrogen gas production method, in which hydrogen is obtained by reacting hydrocarbons obtained from biomass with steam. (3) The third hydrogen gas production method, in which hydrogen is obtained as a by-product of steelworks and chemical plants. (4) The fourth hydrogen gas production method, in which electricity is generated using solar or wind power and the resulting electricity is used to electrolyze water to obtain hydrogen.

[0027] The first hydrogen gas production method is a method for producing hydrogen gas using fossil fuels as energy, and therefore generates CO2 during the hydrogen gas production process. Similarly, the second and third hydrogen gas production methods also generate CO2 during the hydrogen gas production process. The fourth hydrogen gas production method is a method for producing hydrogen gas using natural energy (solar, wind, tidal, geothermal, etc.) as energy, and therefore does not generate CO2 during the hydrogen gas production process.

[0028] The information representing the "hydrogen gas production method" is, for example, identification information that identifies the hydrogen gas production method.

[0029] The information representing the "environmental load" is, for example, information representing the amount of CO2 emissions (or the amount of CO2 reduction) in the process of producing hydrogen gas (for example, a numerical value corresponding to the amount of CO2 emissions).

[0030] The display control unit 52 controls the hydrogen gas derived information display unit 30 so that a display corresponding to the hydrogen gas derived information is displayed on the hydrogen gas derived information display unit 30 based on the hydrogen gas derived information stored in the hydrogen gas derived information storage unit 62.

[0031] The display corresponding to the hydrogen gas origin information is a display whose display form changes according to the hydrogen gas origin information.

[0032] <Example 1> Hereinafter, specific examples of displays corresponding to hydrogen gas origin information (displays whose display form changes depending on the production method of hydrogen gas) will be described.

[0033] It is assumed that the amount of CO2 generated satisfies the following relationship: first hydrogen gas production method > second hydrogen gas production method = third hydrogen gas production method > fourth hydrogen gas production method.

[0034] For example, when information representing a first hydrogen gas production method is stored as hydrogen gas origin information in the hydrogen gas origin information storage unit 62, the display control unit 52 controls the hydrogen gas origin information display unit 30 so that a scale bar b1 shown in Fig. 2(a) is displayed in the hydrogen gas origin information display unit 30 (hydrogen gas origin information display area A) as a display corresponding to the hydrogen gas origin information (hydrogen gas production method). At this time, the scale bar b1 may be displayed in a color (e.g., gray) corresponding to the first hydrogen gas production method.

[0035] Furthermore, when information representing the second or third hydrogen gas production method is stored as hydrogen gas origin information in the hydrogen gas origin information storage unit 62, the display control unit 52 controls the hydrogen gas origin information display unit 30 so that a scale bar b2 longer than the scale bar b1 shown in Fig. 2(b) is displayed in the hydrogen gas origin information display unit 30 (hydrogen gas origin information display area A) as a display corresponding to the hydrogen gas origin information (hydrogen gas production method). At that time, the scale bar b2 may be displayed in a color (e.g., blue) corresponding to the second or third hydrogen gas production method.

[0036] Furthermore, when information representing the fourth hydrogen gas production method is stored as hydrogen gas origin information in the hydrogen gas origin information storage unit 62, the display control unit 52 controls the hydrogen gas origin information display unit 30 so that a scale bar b3 longer than the scale bar b2 shown in Fig. 2(c) is displayed in the hydrogen gas origin information display unit 30 (hydrogen gas origin information display area A) as a display corresponding to the hydrogen gas origin information (hydrogen gas production method). At that time, the scale bar b3 may be displayed in a color (e.g., green) corresponding to the fourth hydrogen gas production method.

[0037] As described above, by changing the display format according to the hydrogen gas origin information (hydrogen gas production method), the user of the vehicle V can understand the origin of the hydrogen gas filled in the fuel tank 20 installed in the vehicle V just by glancing at the display.

[0038] <Example 2> Hereinafter, specific examples of displays corresponding to information derived from hydrogen gas (displays whose display form changes depending on the environmental load) will be described.

[0039] The premise is that the relationship is 1st CO2 emissions > 2nd CO2 emissions > 3rd CO2 emissions.

[0040] For example, when the hydrogen gas origin information storage unit 62 stores a first CO2 emission amount as hydrogen gas origin information, the display control unit 52 controls the hydrogen gas origin information display unit 30 so that a scale bar b1 shown in FIG. 2(a) is displayed in the hydrogen gas origin information display unit 30 (hydrogen gas origin information display area A) as a display corresponding to the hydrogen gas origin information (environmental load). CO 2 emissions Alternatively, the color may be displayed in a color (for example, gray) according to the

[0041] Furthermore, when the second CO2 emission amount is stored as hydrogen gas derived information in the hydrogen gas derived information storage unit 62, the display control unit 52 controls the hydrogen gas derived information display unit 30 so that a scale bar b2 longer than the scale bar b1 shown in Fig. 2(b) is displayed in the hydrogen gas derived information display unit 30 (hydrogen gas derived information display area A) as a display corresponding to the hydrogen gas derived information (environmental load). At this time, the scale bar b2 may be displayed in a color (e.g., blue) corresponding to the second CO2 emission amount.

[0042] Furthermore, when the third CO2 emission amount is stored as hydrogen gas derived information in the hydrogen gas derived information storage unit 62, the display control unit 52 controls the hydrogen gas derived information display unit 30 so that a scale bar b3 longer than the scale bar b2 shown in Fig. 2(c) is displayed in the hydrogen gas derived information display unit 30 (hydrogen gas derived information display area A) as a display corresponding to the hydrogen gas derived information (environmental load). At this time, the scale bar b3 may be displayed in a color (e.g., green) corresponding to the third CO2 emission amount.

[0043] As described above, by changing the display format according to the hydrogen gas origin information (environmental impact), the user of the vehicle V can understand the origin of the hydrogen gas filled in the fuel tank 20 installed in the vehicle V just by glancing at the display.

[0044] The storage unit 60 is, for example, a non-volatile readable / writable storage unit such as a flash memory, etc. The storage unit 60 includes a program storage unit 61 and a hydrogen gas origin information storage unit 62.

[0045] The program storage unit 61 stores a predetermined program to be executed by the control unit 50 (processor).

[0046] Hydrogen gas origin information is stored in the hydrogen gas origin information storage unit 62. This hydrogen gas origin information is wirelessly transmitted from a communication partner device 70 (communication unit 73) installed in the hydrogen gas supply facility ST, as described later.

[0047] The communication partner device 70 is, for example, an information processing device such as a personal computer installed in the hydrogen gas supply facility ST. The communication partner device 70 includes a hydrogen gas origin information storage unit 71, a hydrogen gas origin information providing unit 72, a communication unit 73, and the like.

[0048] The hydrogen gas origin information storage unit 71 is, for example, a non-volatile storage unit such as a hard disk device, a ROM, etc. The hydrogen gas origin information storage unit 71 stores hydrogen gas origin information of the hydrogen gas stored in a hydrogen gas storage unit (not shown) installed in the hydrogen gas supply facility ST.

[0049] The hydrogen gas origin information providing unit 72 reads out hydrogen gas origin information corresponding to the hydrogen gas to be filled into the fuel tank 20 installed in the vehicle V from the hydrogen gas origin information storage unit 71, and wirelessly transmits the read hydrogen gas origin information via the communication unit 73.

[0050] The communication unit 73 is a communication device that performs wireless communication with the communication unit 40 .

[0051] Next, an example of the operation of the hydrogen gas origin information display system 1 having the above configuration will be described.

[0052] FIG. 3 is a flowchart of the hydrogen gas origin information display system 1.

[0053] In the following explanation, it is assumed that hydrogen gas produced in a hydrogen production facility (not shown) is delivered to a hydrogen gas supply facility ST by a hydrogen gas delivery vehicle (not shown) and stored in a hydrogen gas storage unit (not shown) installed in the hydrogen gas supply facility ST. It is also assumed that hydrogen gas origin information for the hydrogen gas stored in the hydrogen gas storage unit is stored in the hydrogen gas origin information storage unit 71. This hydrogen gas origin information is, for example, input by a staff member or the like at the hydrogen gas supply facility ST (or wirelessly transmitted from the hydrogen gas delivery vehicle).

[0054] The following process begins when a user of vehicle V who has arrived at a hydrogen gas supply facility ST informs a staff member or other person at the hydrogen gas supply facility ST that he or she wishes to fill the fuel tank 20 installed in the vehicle V with hydrogen gas, and the staff member or other person performs a specified operation.

[0055] First, hydrogen gas origin information of the hydrogen gas to be filled into the fuel tank 20 mounted on the vehicle V is transmitted (step S10). This is realized by the hydrogen gas origin information providing unit 72 reading out hydrogen gas origin information corresponding to the hydrogen gas to be filled into the fuel tank 20 mounted on the vehicle V from the hydrogen gas origin information storage unit 71, and wirelessly transmitting the read hydrogen gas origin information via the communication unit 73.

[0056] Next, hydrogen gas origin information is acquired (step S11). This is realized by the hydrogen gas origin information acquisition unit 51 acquiring the hydrogen gas origin information transmitted in step S10 via the communication unit 40. This acquired hydrogen gas origin information is stored in the hydrogen gas origin information storage unit 62 (step S12).

[0057] Next, a display corresponding to the hydrogen gas origin information is displayed (step S13). This is realized by the display control unit 52 controlling the hydrogen gas origin information display unit 30 so that a display corresponding to the hydrogen gas origin information (see FIG. 2) is displayed on the hydrogen gas origin information display unit 30 (hydrogen gas origin information display area A) based on the hydrogen gas origin information stored in the hydrogen gas origin information storage unit 62 in step S12.

[0058] According to the first embodiment, the user can understand the origin of the hydrogen gas filled in the fuel tank 20 mounted on the vehicle V. This can increase environmental awareness.

[0059] This is because the display control unit 52 displays a display corresponding to the hydrogen gas origin information on the hydrogen gas origin information display unit 30 based on the hydrogen gas origin information stored in the hydrogen gas origin information storage unit 62.

[0060] The display corresponding to the hydrogen gas origin information can be displayed on the hydrogen gas origin information display unit 30 not only when hydrogen gas is filled at the hydrogen gas supply facility ST, but also at an appropriate timing (for example, when the ignition is turned on) after leaving the hydrogen gas supply facility ST. Also, the display corresponding to the hydrogen gas origin information may be displayed on the hydrogen gas origin information display unit 30 at all times.

[0061] Next, a modified example will be described.

[0062] In the above-mentioned embodiment 1, an example has been described in which the display corresponding to the hydrogen gas origin information is a display (scale bars b1 to b3) whose length changes according to the hydrogen gas origin information, but this is not limited thereto. For example, the display corresponding to the hydrogen gas origin information may be a display whose length does not change and whose color only changes according to the hydrogen gas origin information.

[0063] In the above embodiment, the program includes a set of instructions (or software code) that, when loaded into a computer, causes the computer to perform one or more functions described in the embodiment. The program may be stored in a non-transitory computer-readable medium or a tangible storage medium. By way of example and not limitation, the computer-readable medium or tangible storage medium includes random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drive (SSD) or other memory technology, CD-ROM, digital versatile disc (DVD), Blu-ray® disk or other optical disk storage, magnetic cassette, magnetic tape, magnetic disk storage or other magnetic storage device. The program may be transmitted on a transitory computer-readable medium or communication medium. By way of example and not limitation, the transitory computer-readable medium or communication medium includes electrical, optical, acoustic, or other forms of propagated signals.

[0064] All the numerical values ​​shown in the above embodiment are merely examples, and it goes without saying that other appropriate numerical values ​​can be used.

[0065] The above-described embodiment is merely an example in all respects. The present invention should not be construed as being limited by the description of the above-described embodiment. The present invention can be implemented in various other forms without departing from the spirit or main characteristics thereof. [Explanation of symbols]
