Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cells, in particular to a safety gas storage cylinder for hydrogen fuel cells. Background Art

[0002] Hydrogen fuel cells use the chemical element hydrogen to create batteries that store energy. The hydrogen element it needs is generally stored in the form of gas in gas cylinders. Gas cylinders can store compressed air, maintain a stable pressure inside the cylinder, and achieve a balance between gas supply and gas consumption.

[0003] During the process of filling the gas cylinder, there is a disadvantage that the pressure inside the cylinder cannot be measured in time. At the same time, due to the lack of cooling material, the internal temperature is easily high, and the hydrogen burns and explodes. When filling the gas, the gas pressure changes in the gas cylinder, which will cause the gas cylinder to shake and cause the air pump connection to loosen, resulting in hydrogen leakage.

[0032] When the air is in the air, the bottle 11 can be placed in the side support frame 12 so that the lower end surface of the bottle 11 contacts the support base 16 and the upper end surface of the elastic bottom plate 22.
