The bipolar plate of the Hydrogen Fuel Cell is made of metal, which is very light in weight. The open air-cooled structure is designed to facilitate the electrochemical reaction between the air entering the fuel cell and the hydrogen entering the fuel cell so as to generate electric energy. The Power System Hydrogen Fuel Cell is equipped with a light fan to help cool down and send more oxygen. The speed of the fan can be adjusted automatically and manually according to the temperature, which is very convenient and fast.
