Problems solved by technology

Both the high-pressure hydrogen cylinder method and the low-temperature liquefied hydrogen method have disadvantages such as high cost and poor safety during use and transportation; carbon material adsorption hydrogen storage is still in the research stage
The metal hydride solid-state hydrogen storage method is a simple, cheap, and safe hydrogen storage method. However, in actual operation, the metal hydride hydrogen storage tank needs to be supplemented by a hydrogen source with sufficient pressure before it can be used repeatedly. It is extremely inconvenient for mobile applications.

[0048] Example 1 The hydrogen supply method of the integrated mobile hydrogen production and hydrogen storage device: the hydrogen generator adopts the reaction of metal or compound with water to produce hydrogen, and the produced hydrogen enters the gas-water separator after being cooled by a serpentine tube, and the gas-water The separator drains water to realize the gas-water separation process of the gas-water separator. The hydrogen after gas-water separation passes through a hydrogen purifier equipped with a desiccant, and the desiccant absorbs the moisture in the hydrogen to realize the purification process of the hydrogen by the hydrogen purifier. Allow the hydrogen storage tank to store hydrogen by turning down the water bath temperature. When using hydrogen, the hydrogen storage tank is supplied with hydrogen by increasing the temperature of the water bath.
