Hydrogen fuel cell vehicles utilize the reverse reaction principle of electrolyzing water. The hydrogen energy stored in the on-board hydrogen storage tank is combined with oxygen in the air to generate electric current for the motor to operate. Therefore, a hydrogen fuel cell is essentially a power generation device rather than an energy storage battery. Since only water is produced after hydrogen combines with oxygen, the power generation process of hydrogen fuel cells will not cause any adverse impacts on the environment, with outstanding environmental protection effects.

For a long time, what people have criticized the most about electric vehicles is the unstable driving range and the slow charging speed. Hydrogen fuel has strong low-temperature adaptability and can start working normally at a low temperature of -30°C. Moreover, the energy density of hydrogen energy is as high as 143MJ/kg, which is almost three times that of gasoline (44MJ/kg for gasoline). Coupled with the fact that the hydrogen refueling process can be as quick as refueling a fuel vehicle, with immediate departure after stopping. Therefore, hydrogen fuel cell vehicles are hailed as the "ultimate goal" of future new energy vehicles.
