Problems solved by technology

[0004] Since the fuel cell will produce water in the above reaction process, if the fuel cell is started or operated in a negative temperature environment (such as a low-temperature environment such as mountains and polar regions with a temperature below 0°C), water may be deposited on the surface of the proton exchange membrane. Icing occurs, causing the proton exchange membrane to be pierced by ice and damaged
In addition, if the reactant of fuel cell chemical hydrogen production is water, the water will freeze at negative temperature, resulting in the inability to react with other reactants for hydrogen production
