Technology

Hydrogen is fuel. Pure and simple.

Hydrogen is the most abundant element in the universe. It’s found in plants, manure, and water.

With such abundant availability, it makes perfect sense to use hydrogen to power our vehicles.

Something
in the Water

Hydrogen can be extracted from water through a process called electrolysis. Passing an electrical current through water creates a chemical reaction where the result is the separation of water’s two main elements - hydrogen and oxygen.

Hydrogen is lighter than air and free of impurities.

HOW DOES IT WORK?

Don’t worry, there’s nothing complicated about driving hydrogen fuel cell electric vehicles.

You fuel up with hydrogen in the same way you would a gas-powered vehicle. The hydrogen is stored in carbon fibre, high-impact resistant tanks. When the vehicle is fueled with hydrogen, and combined with oxygen from outside the vehicle, the chemical reaction that occurs generates electricity. What’s more, energy is captured every time you hit the brakes, conserving power and creating even better efficiency.

Power Control Unit (PCU)

Based on the unit used in Prius, the FCEV’s PCU controls energy output by deciding when to use stored energy from the battery, or draw directly from the fuel cell stack.

Electric Motor

When you press the accelerator pedal, electricity from the fuel cell stack is sent to the motor.

Fuel Cell Stack

Hydrogen travels from the tanks to the fuel cell stack. There, it goes through a chemical reaction involving oxygen in the air – creating the electricity that powers the vehicle.

Boost Converter

Uses the same battery from Toyota Hybrid Vehicles and increases the voltage to 650 volts, increasing performance and making more efficient use of the electric motor.

Battery

Using Toyota’s proven Hybrid technology, recaptured energy from braking is stored in the sealed Nickel-Metal Hydride Battery, providing power output and assisting 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.

SAFETY FIRST

Toyota’s vision for the future of mobility puts safety first and foremost.

Advanced safety innovations, specially designed for hydrogen fuel cell electric vehicles.

Our tanks are designed not to leak

Our multi-patented, carbon-fiber-wrapped, polymer-lined hydrogen tanks, are built in a three-layer structure and absorb five times the crash energy of steel.

In a high speed collision, sensors stop the flow of hydrogen

To prevent hydrogen from traveling to potentially damaged systems outside of the tank, the system automatically shuts the tank’s hydrogen output valve.

Any leaked hydrogen is quickly dispersed

All hydrogen-related parts are located outside the cabin and designed to help ensure leaked hydrogen doesn’t build up.

Hydrogen escapes safely into the atmosphere

Since hydrogen gas is lighter than air, it rapidly disperses, reducing the potential for damage in the event of an ignition.

Next Generation Mirai

Coming soon, the totally redesigned Mirai is a major step forward for fuel cell electric vehicles, displaying a significantly greater range, improved driving performance and an elegant, sporty design. Built on Toyota’s latest platform, the next generation Mirai features a rigid body and low centre of gravity, which makes for nimble and rewarding handling.
