The fuel cell stack, electric motor, battery and hydrogen tank are the main components of the Fuel Cell Electric Vehicle (FCEV), that is, ix35 Fuel Cell. When hydrogen stored in the tank enters the fuel cell stack, broken down into protons and electrons. The flow of electrons created in the fuel cell provides electricity, and the protons react with oxygen molecules from the air, generating heat and water. Electricity generated from the fuel cell is first transmitted to the inverter and then to the motor, which creates power that turns the wheel, making the vehicle move.
