Fuel cell electric car introduction
Fuel Cell Electric Vehicle (FCEV) utilizes hydrogen and oxygen in the air under the action of a catalyst. An electric vehicle that is driven by an electrochemical reaction in a fuel cell as a main power source. Fuel cell electric vehicles are essentially one type of pure electric vehicles. The main difference is that the working principle of power batteries is different. In general, fuel cells convert chemical energy into electrical energy through electrochemical reactions. Hydrogen is required for electrochemical reactions, and oxygen is used for oxidants. Therefore, the first developed fuel cell electric vehicles use hydrogen fuel directly. The hydrogen can be stored in the form of liquefied hydrogen, compressed hydrogen or metal hydride hydrogen storage.
