Hydrogen Fuel Cell Electric
Hydrogen Fuel Cell Electric
Zero Emissions. Unlimited Potential
Imagine a vehicle so clean that it emits only water from its tailpipe. That’s the power and potential of Toyota’s revolutionary hydrogen fuel cell electric (FCEV) technology. Brought to life in the Toyota Mirai.
BENEFITS
Power. Pure and Simple
Hydrogen is the most abundant element in the universe. And that’s just the start of what makes it such an ideal power source.
CLEAN
When hydrogen is made using renewable energy, it is completely carbon-free. When used to power an FCEV, like Mirai, the only tailpipe emission is water vapour.
EFFICIENT
Electricity is produced onboard, and supplied to the electric motor as needed. Excess energy is stored in a compact battery pack.
FAMILIAR
There’s no need to change your driving habits. Where refuelling infrastructure exists, simply fill the hydrogen fuel tank and you are ready to enjoy zero emissions driving at its finest.
HOW FCEVS WORK
Simple. Safe. Revolutionary
Toyota’s revolutionary fuel cell stack creates the electricity that drives the vehicle through a chemical reaction between hydrogen that is stored on board, and oxygen from the atmosphere.
POWER CONTROL UNIT (PCU)
The PCU controls energy output by deciding when to use stored energy from the battery or draw directly from the fuel cell stack.
ELECTRICAL MOTOR
Press the accelerator pedal and electricity from the fuel cell stack is sent to the motor.
FUEL CELL STACK
In the fuel cell stack, hydrogen and oxygen from the air combine in a chemical reaction that creates electricity to power the electric motor.
BOOST CONVERTER
Uses the same battery as a Toyota Hybrid Electric Vehicle, increasing the voltage to 650 volts, enhancing performance and making more efficient use of the electric motor
BATTERY
Energy, recaptured during braking, is used to recharge the battery, and assist when high power is required, such as during acceleration.
HYDROGEN TANKS
Hydrogen is pumped into the vehicle and stored in carbon-fibre reinforced, polymer lined tanks, designed for safe fuel storage.
