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. A hydrogen fuel cell car is a car that uses hydrogen or hydrogen-containing substances to react with oxygen in the air in a fuel cell to generate electricity to drive the motor, which then propels the vehicle. The widespread use of hydrogen fuel as a transportation energy source is a key factor in the hydrogen economy.
