Hydrogen-oxygen fuel cells directly convert hydrogen energy into electrical energy through chemical reactions. Compared with traditional internal combustion generators, they are not restricted by the Carnot cycle, have a high energy conversion rate, and are pollution-free, making them an ideal power source.

The hydrogen discharge pipe 4 is used to discharge hydrogen for subsequent use, and the hydrogen discharge pipe 4 is also provided with a control valve.

[0026] An explosion-proof component is provided on the upper surface of the device box 1 to prevent the hydrogen production tank 5 from leaking and causing the risk of explosion. The explosion-proof component is connected to the inside of the device box 1. A hydrogen detector 17 is provided at the upper right end of the inner wall of the device box 1.
