Due to its high calorific value, good combustion performance, clean and pollution-free nature, diverse utilization forms, and strong adaptability, hydrogen energy is widely used in transportation, industry, and construction. Hydrogen production and refueling equipment is a system that integrates hydrogen production and refueling functions. It is mainly used in hydrogen refueling stations to provide hydrogen fuel for hydrogen energy application equipment such as hydrogen-powered vehicles.

[0003] Highly integrated hydrogen production and refueling devices have been widely used due to their high integration and ease of use. However, these devices have limited internal space, and the components generate a significant amount of heat during operation. The hydrogen produced by these devices is highly susceptible to combustion and explosion in high-temperature and static-filled environments. Therefore, if the heat generated during hydrogen production and refueling cannot be dissipated in a timely manner, there will be a high safety risk. Utility Model Content

The purification component 21 is used to purify and refine the decomposed hydrogen. The compression and storage component 22 is used to compress and store the purified hydrogen.

[0034] Furthermore, such as Figure 3 As shown, the purification component 21 includes a cooling module 29 and a hydrogen purification module 30 disposed next to the cooling module 29. The compression and storage component 22 includes a compressor module 31 and a storage tank 32 connected to the compressor module 31.

The tortuous hydrogen exhaust pipe 9 is also used to cool the hydrogen that is about to be discharged.

[0036] like Figures 1-6 As shown, the principle of a small, highly integrated hydrogen production and refueling device provided in this embodiment is as follows: When using the device, an appropriate amount of water is first injected into the electrolysis reaction module 24 through the water inlet pipe 25. The operator controls the overall operation of the device through the control panel 33, selects a suitable bayonet according to the specific interface of the instrument to be hydrogenated, connects the suitable bayonet to the tortuous hydrogen discharge pipe 9, and then installs the instrument to be hydrogenated on the suitable bayonet.

[0037] Water entering the electrolysis reaction module 24 is decomposed into hydrogen and oxygen through electrolysis. The oxygen separation device 26 separates the oxygen from the gas produced by the electrolysis reaction and discharges it to the outside or collects it separately through the oxygen exhaust pipe 27. The hydrogen separation device 28 separates the hydrogen from the gas produced by the electrolysis reaction and transmits it to the cooling module 29 through a pipeline. The cooling module 29 performs preliminary cooling of the hydrogen and removes moisture and impurities from the hydrogen. The hydrogen then enters the hydrogen purification module 30 through a pipeline. The hydrogen purification module 30 purifies the incoming hydrogen to ensure that the hydrogen purity meets the usage standards. The hydrogen then enters the compressor module 31 through a pipeline. The compressor module 31 compresses the purified hydrogen. The compressed hydrogen is transported to the storage tank 32 through a pipeline. Under the action of the filling machine 23, the hydrogen is extracted from the storage tank 32 and discharged through the tortuous hydrogen exhaust pipe 9 to add hydrogen to the instrument to be hydrogenated.

[0038] When the device is in operation, the air vent cover 10, which is slidably installed on the front and rear faces of the protective enclosure 6, should be opened first. When the hydrogen production and refueling structure 1 is in operation, the operator controls several drive motors 13 to drive several fan blades 14 to rotate through the control panel 33. The air-cooling component 4 on one side of the protective box 2 draws outside air into the protective box 2, and the air-cooling component 4 on the other opposite side of the protective box 2 extracts the high-temperature air in the protective box 2 to the outside, so that the air in the protective box 2 can be exchanged and circulated, so as to quickly remove the high temperature generated in the hydrogen production and refueling structure 1 due to operation.
