Fuel cell vehicles may rise in the near future

Compared with the heat of pure electric vehicles and hybrid cars, fuel cell cars have always been low-key. In fact, fuel cell technology has made significant progress in recent years. Perhaps in the near future, fuel cell vehicles will rise suddenly.

A fuel cell vehicle is a kind of electric vehicle. The energy of its battery is directly converted into electricity through the chemical action of hydrogen and oxygen instead of being burned. Fuel cell chemical reaction process will not produce harmful products, so the fuel cell vehicle is a pollution-free car, the fuel cell energy conversion efficiency is 2-3 times higher than the internal combustion engine, so from the energy use and environmental protection, the fuel cell car is An ideal vehicle.

Hydrogen fuels for fuel cell vehicles can be obtained in several ways. Some vehicles directly carry pure hydrogen fuel. In addition, some vehicles in fuel cell vehicle engines may have fuel reformers that can convert hydrocarbon fuels into hydrogen-rich gas. Individual fuel cells must be combined into fuel cell stacks in order to obtain the necessary power to meet the requirements of vehicle use.

Specifically, the fuel cell car operates on the principle that hydrogen used as a fuel chemically reacts with oxygen in the air in a fuel cell mounted in an automobile to generate electric energy to start the motor and drive the automobile. Methanol, natural gas and gasoline can also replace hydrogen (indirect extraction of hydrogen from these substances), but it will produce extremely low carbon dioxide and nitrogen oxides. But in general, such chemical reactions produce only water in addition to electricity.

Compared with traditional automobiles, fuel cell vehicles have the following advantages: zero emissions or nearly zero emissions; reduced water pollution caused by oil leakage, reduced greenhouse gas emissions; improved fuel economy and engine combustion efficiency; smooth operation, No noise.
