In the Toyota Mirai, compressed hydrogen fuel is stored in three 10,000-psi carbon-fiber-reinforced high-pressure tanks: one mounted longitudinally in the center of the car; another mounted transversely under the rear seat, and a third below the battery. Cooling air for the battery is silently pulled in from the cabin.

kWh lithium-ion battery pack (from the Jetta Hybrid), which stores the kinetic energy recovered from regenerative braking; assists in the starting phase of the fuel cell; and adds a dynamic boost to the maximum acceleration of the Golf SportWagen. The hydrogen is stored in the tanks at a pressure of 700 bar (10,150 psi).

When the car is braked it stores the recovered energy. The storage battery operates over the range of 220 to 460 volts—a 3-way DC/DC converter in the engine compartment equalizes the difference compared with the fuel cell’s voltage level. 3-way power DC/DC converter. mi)—i.e., about 6 kg.

The electric turbocharger brings about another advantage: it uses parts of the surplus energy from the exhaust system to generate electricity, and either stores it in the high-voltage lithium-ion battery as part of recuperation or provides additional drive power by feeding it to an additional electric motor.
