The Honda Clarity and Toyota Mirai

We look inside the cars that split hydrogen to generate energy

Power control unit

This unit manages the power from the fuel cell stack to the battery, and readies its supply to the motor.

Fuel cell stack

a set of stacks use the hydrogen fuel to generate electricity, which then powers the motor and is stored by the battery.

Hydrogen tanks

The Mirai features two high-pressure carbon fibre tanks to maximise hydrogen storage.

Drive battery

The battery stores energy generated by the fuel cell stack and provides power when it is needed quickly, such as standing starts and rapid acceleration.

Hydrogen tanks

The tanks are built from strong and light carbon fiber, and mounted within the cars frame to protect against damage in the event of an impact.
