Description
technical field [0001] The embodiments of the present invention relate to the field of battery cooling, and in particular to a fuel cell water cooling device and system. Background technique [0002] Hydrogen fuel cell belongs to proton exchange membrane fuel cell. As an important part of new energy, it converts the chemical energy in hydrogen and oxidant into electrical energy through electrochemical reaction. The conversion is efficient and environmentally friendly, replacing the traditional form of combustion power generation. The operating temperature of the hydrogen fuel cell will affect the gas transmission characteristics, the water content of the reaction membrane, the catalytic activity of the catalytic layer, etc. The optimum operating temperature of the hydrogen fuel cell is generally 60-70 ° C. Under normal circumstances, the heat generated will be taken away through the cooling system to ensure that the hydrogen fuel cell works in a suitable temperature environm...
