There are two types of hydrogen cars. One is a hydrogen internal combustion engine car, which uses an internal combustion engine to burn hydrogen (usually obtained by decomposing methane or electrolyzing water) to generate power to propel the car. The other is a hydrogen fuel cell car, which reacts hydrogen or hydrogen-containing substances with oxygen in the air in a fuel cell to generate electricity to propel the motor, which in turn propels the vehicle. Hydrogen fuel is widely used as a transportation energy source. High-speed vehicles, buses, submarines, and rockets have already used hydrogen energy in different forms.
