Fuel cell electric vehicles use the air force and oxygen in the air under the action of a catalyst, electric cars driven by electrochemical reactions in fuel cells as the main power source. fuel cell electric vehicles are essentially a type of pure electric vehicle, the main difference is that the working principle of power batteries is different. generally speaking, fuel cells convert chemical energy into electricity through electrochemical reactions, the reducing agent required for electrochemical reactions generally uses hydrogen, oxidant use oxygen, therefore, the earliest developed fuel cell electric vehicles mostly used hydrogen fuel directly, hydrogen can be stored using liquefied hydrogen, Compressed hydrogen or metal hydride hydrogen storage.
Compared with traditional cars, fuel cell vehicles have the following advantages:
1.Zero or near-zero emissions
2.Reduced water pollution from oil leaks
3.Reduced water pollution from oil leaks
4.The high conversion efficiency of fuel cells (about 60%),, Good vehicle fuel economy
5.Smooth and noiseless operation
Disadvantages:
the cost of fuel cells is high, and the cost of use (hydrogen) is also expensive
