Hydrogen Fuel Cell Use in a Car

• Hydrogen powered cars are being designed by dozens of different automobile manufacturers and each designs their cars differently. At the current level of hydrogen technology, the basic process is about the same in most vehicles. A hydrogen tank in the back of the car stores the hydrogen gas, not unlike that of a gasoline tank.

The hydrogen mixes with oxygen in the air as it flows into the fuel cell stack, which uses an electrochemical process to generate electricity. Some of this electricity goes to the motor and the rest is used to keep a battery, such as a lithium-ion battery, charged.

The battery is usually used as a backup energy source. The electricity flows into the power drive unit, which governs the flow of electricity into the electric drive motor.

The motor propels the vehicle like a regular electric motor does. Various safety systems are employed by most hydrogen vehicles, including a ventilation system and an automatic shut off in case of a hydrogen leak, a collision system that automatically shuts off the flow of hydrogen and electricity, and a refueling safety system to prevent reverse airflow of hydrogen, prevent contamination by other gases, and make sure that the hydrogen is stored at compatible pressure levels within the tank.
