[0047] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0048] The following is for reference. Figures 1-5 Describes a hydrogen production module according to an embodiment of this application.

[0049] like Figure 1 and Figure 2 As shown, the hydrogen production module includes a housing 100, a hydrogen production module 200, and an electronic control module 300.

[0050] The housing 100 has a receiving cavity, and the receiving cavity is provided with a partition plate 130. The partition plate 130 divides the receiving cavity to form a hydrogen production area 140 and an electronic control area 150.

[0051] Specifically, the hydrogen production area 140 and the electronic control area 150 are vertically spaced apart, and the hydrogen production area 140 is located below the electronic control area 150. Of course, in some other embodiments, the hydrogen production area 140 and the electronic control area 150 may also be horizontally spaced apart, and this embodiment does not impose any restrictions.

[0052] The housing 100 is provided with a plurality of first connectors 110 and second connectors 120 on one side. The first connectors 110 are used for fluid inflow or outflow; the second connectors 120 are used for electrical signal transmission and power supply.

[0053] The hydrogen production module 200 is located within the hydrogen production area 140, and the interface of the hydrogen production module 200 is connected to the first connector 110 in a one-to-one correspondence; the electronic control module 300 is located within the electronic control area 150 and is electrically connected to the hydrogen production module 200, and the interface of the electronic control module 300 is connected to the second connector 120 in a one-to-one correspondence.

[0054] Specifically, the electronic control module 300 includes a controller 310 and a control power supply 320; the control power supply 320 is electrically connected to the controller 310 to supply power to the controller 310; the controller 310 is electrically connected to the hydrogen production module 200 to control the relevant components of the hydrogen production module 200 and realize the monitoring of the hydrogen production process; the input interface of the control power supply 320 is connected to the second connector 120.

[0055] In actual operation, a control screen is also provided on one side of the housing 100. The control screen is connected to the controller 310 of the electronic control module 300. The control screen can display and adjust key parameters in the hydrogen production process, such as the target hydrogen production, the working voltage and current of the electrolyzer 230 of the hydrogen production module 200, etc.

[0056] In this embodiment, all the first connectors 110 and the second connectors 120 are centrally arranged on one side of the housing 100, so that the operator can complete the wiring of all the first connectors 110 and the second connectors 120 to external devices (such as pure water modules) without having to go around to different sides of the housing 100. This can greatly improve the convenience and efficiency of wiring.

[0057] This application divides the accommodating cavity into a hydrogen production area 140 and an electrical control area 150 using a partition plate 130. A hydrogen production module 200 is installed in the hydrogen production area 140, and an electrical control module 300 is installed in the electrical control area 150. This prevents the hydrogen or water vapor mixture from the hydrogen production module 200 from coming into contact with the electrical components of the electrical control module 300, thereby reducing the risk of accidents and improving the safety of the hydrogen production module.

[0058] like Figure 4 and Figure 5 As shown, in some embodiments, the hydrogen production module 200 is positioned close to the pure water module; the hydrogen production module 200 includes a water tank 210, a water pump 2211, an electrolyzer 230, and a gas-liquid separator 240 connected in sequence by pipelines; the gas-liquid separator 240 is connected to a pure water discharge path 241; the first connector 110 includes a pure water discharge connector 111, which is used to connect to the water supply tank 210 of the pure water module by pipeline.

[0059] This embodiment may have the following two structural forms:

[0060] like Figure 4 As shown, in structural form one: the pure water discharge path 241 is connected to the pure water discharge connector 111.

[0061] like Figure 5 As shown, in the second structural form: the end of the pure water discharge path 241 is connected to a pressure relief container 2411, and the pressure relief container 2411 is connected to the pure water discharge connector 111.

[0062] It should be noted that under high pressure, some hydrogen may dissolve in the separated pure water. To prevent the pure water with dissolved hydrogen from directly entering the water tank 210 and mixing with oxygen, the separated pure water needs to be transported to the pressure relief container 2411 to release the dissolved hydrogen before the pure water is introduced into the water tank 210. Therefore, when the pressure inside the gas-liquid separator 240 is high, structural form two can be used; when the pressure inside the gas-liquid separator is low, structural form one can be used.

[0063] In some embodiments, the pure water discharge path 111 is also provided with a throttling pipe and a first solenoid valve, with the two ends of the throttling pipe connected to the gas-liquid separator and the first solenoid valve respectively (not shown).

[0064] Existing throttle valves are prone to accidental contact during transportation or use, causing changes in valve opening and unstable flow rates. In this embodiment, a throttle tube is used instead of a throttle valve, which is easier to transport, has lower cost, simpler structure, stable throttling effect, and lower maintenance cost.

[0065] Furthermore, the water tank 210 is also provided with a pure water inlet 212, and the first connector 110 includes a pure water inlet connector 116; the pure water inlet 212 is connected to the pure water inlet connector 116 to maintain the dynamic balance of water circulation in the hydrogen production module 200 and ensure the stability of the hydrogen production process.

[0066] like Figure 3 and Figure 4 As shown, in some embodiments, the gas-liquid separator 240 is also connected to a purification path 242, on which a first one-way valve 2421 and a first heat exchanger 2422 are sequentially arranged; the first connector 110 also includes a purification connector 112; the end of the purification path 242 is connected to the purification connector 112, which is used to connect to the purification module.

[0067] In this embodiment, the hydrogen produced by the electrolysis reaction contains a small amount of water. After preliminary separation by the gas-liquid separator 240, the hydrogen flows to the purification path 242. A first one-way valve 2421 and a first heat exchanger 2422 are sequentially arranged on the purification path 242. The first one-way valve 2421 can prevent external gases from entering the pipe. The first heat exchanger 2422 reduces the temperature of the hydrogen through heat exchange, which facilitates subsequent purification. In some embodiments, for hydrogen production modules with small hydrogen production capacity, the hydrogen discharged from the gas-liquid separator 240 can be cooled naturally through the pipeline, and the first heat exchanger 2422 can be omitted.

[0068] In some embodiments, the gas-liquid separator 240 is further connected to a first hydrogen emission path 243, on which a second solenoid valve 2431 and a second check valve 2432 are sequentially provided; the first connector 110 further includes a hydrogen emission connector 113; the end of the first hydrogen emission path 243 is connected to the hydrogen emission connector 113.

[0069] In this embodiment, in the event of an unexpected power outage or malfunction, the second solenoid valve 2431 is in the open state. At this time, the residual hydrogen in the gas-liquid separator 240 will be rapidly released through the first hydrogen discharge path 243, thereby preventing hydrogen stagnation and reducing safety hazards such as explosions. The second one-way valve 2432 can prevent external gas from flowing back from the first hydrogen discharge path 243 to the gas-liquid separator 240 due to external pressure fluctuations.

[0070] Furthermore, a back pressure valve (not shown) is provided between the end of the first hydrogen emission path and the hydrogen emission connector. It should be noted that without the back pressure valve, if the pressure of the gas-liquid separator at the hydrogen end is too low when the hydrogen production module operates alone, the liquid cannot be discharged, causing liquid to escape from the hydrogen outlet pipe. This embodiment incorporates a back pressure valve, allowing the hydrogen production module to operate independently, making it suitable for various application scenarios that do not require connection to a purification module.

[0071] In some embodiments, the gas-liquid separator 240 is further connected to a second hydrogen emission path 244, the second hydrogen emission path 244 is provided with a safety valve 2441 and is connected to the first hydrogen emission path 243 through the safety valve 2441, and the end of the second hydrogen emission path 244 is connected to the hydrogen emission connector 113.

[0072] In this embodiment, the safety valve 2441 opens when the pipeline pressure between the electrolyzer 230 and the gas-liquid separator 240 exceeds a preset threshold, so as to discharge excess hydrogen from the second hydrogen emission path 244.

[0073] In some embodiments, a first connection path 221 is provided between the water tank 210 and the electrolytic cell 230, and the water pump 2211 and the second heat exchanger 2212 are sequentially arranged on the first connection path 221.

[0074] In this embodiment, the second heat exchanger 2212 adjusts the water transported from the water tank 210 to the electrolyzer 230 to a preset temperature range through heat exchange, thereby facilitating the electrolysis of the electrolyzer 230 and optimizing the hydrogen production efficiency.

[0075] Furthermore, a second connection path 222 connects the water tank 210 and the electrolytic cell 230. A deionizer 2221 is installed on the second connection path 222, and the deionizer 2221 is located downstream of the second heat exchanger 2212. The deionizer 2221 can remove ionic impurities (such as calcium, magnesium, sodium, and chloride ions) from the water, thereby improving the purity of the supplied water and reducing the occurrence of side reactions.

[0076] In some embodiments, the water tank 210 is also connected to an oxygen discharge path 223, and the water tank 210 is provided with an oxygen discharge port communicating with the oxygen discharge path 223; the first connector 110 also includes an oxygen discharge connector 114, and the oxygen discharge port pipeline is connected to the oxygen discharge connector 114.

[0077] In some embodiments, the water tank 210 is further provided with a wastewater discharge path 211; the first connector 110 includes a wastewater discharge connector 115; the wastewater discharge path 211 is connected to the wastewater discharge connector 115. In this embodiment, through the design of the wastewater discharge path 211, water that does not meet the water quality requirements in the water tank 210 can be discharged, and then pure water can be added to ensure water quality.
