Fuel Cell System
The fuel cell system is composed of 1) the fuel
cell which generates electric energy through a
electro-chemical reaction between the
hydrogen and oxygen, 2) the hydrogen supply
system which supplies the hydrogen (fuel), 3)
the heat control system which manages the heat
and 4) the air supply system which supplies
oxygen. The electricity generated by the fuel
cell system powers the high-voltage battery and
the electric motor and makes the vehicle move.
