How the Toyota Mirai Engine Works
The Toyota Mirai is a hydrogen fuel cell vehicle, which means it uses a fuel cell stack to generate electricity from hydrogen to power the vehicle. Here’s how the engine of the Toyota Mirai works:
1. Fuel Cell Stack: At the core of the Mirai is the fuel cell stack. This stack consists of multiple fuel cells that contain a catalyst-coated membrane. Hydrogen gas is supplied to one side of the membrane, while oxygen from the air is supplied to the other side. The hydrogen molecules are split into protons and electrons, with the protons passing through the membrane while the electrons are forced to travel through an external circuit, creating an electric current.
2. Electric Motor: The electric current produced by the fuel cell stack is used to power an electric motor, which drives the wheels of the Mirai. The electric motor provides instant torque and smooth acceleration, making the Mirai a responsive and efficient vehicle.
3. Hydrogen Fueling: The Mirai is fueled with hydrogen, which is stored in high-pressure tanks located in the vehicle. When the hydrogen is consumed in the fuel cell stack, the only byproduct is water vapor, making the Mirai a zero-emission vehicle.
4. Range: The Mirai has an impressive driving range. For example, the 2024 Mirai XLE has an EPA-estimated driving range of 402 miles when fully fueled with hydrogen, while the 2024 Mirai Limited has an EPA-estimated driving range of 357 miles.
It’s important to note that the Toyota Mirai is designed to be a hydrogen fuel cell vehicle and does not have a traditional internal combustion engine. Instead, it relies on the chemical reaction between hydrogen and oxygen to generate electricity and power the vehicle.

What kind of engine is in a Toyota Mirai?
fuel-cell electric powertrain
The Toyota Mirai relies on a fuel-cell electric powertrain, which converts hydrogen gas into electricity. Essentially, this is a chemical laboratory on wheels. The electric motor powering the Mirai produces 182 horsepower, and a direct-drive transmission sends those ponies to the rear wheels.
Is there a downside to hydrogen cars?
More energy- and labor-intensive to store and transport hydrogen than gasoline or diesel fuel. Fuel cells are expensive to replace. Safety concerns over hydrogen flammability and electrical shock. Maintenance costs remain unclear.
Do you have to charge a Toyota Mirai?
In essence, the Mirai is a “plug-less” electric vehicle. Instead of having to charge a battery in a BEV which can take several hours, the Fuel Cell Electric Vehicle (FCEV) driver simply fills the tank with hydrogen, just as millions of drivers do every day with gas vehicles.
How does a hydrogen fuel engine work?
How They Work. Fuel cell cars are powered by compressed hydrogen gas that feeds into an onboard fuel cell stack that doesn’t burn the gas, but instead transforms the fuel’s chemical energy into electrical energy. This electricity then powers the car’s electric motors.
Which Toyota engine runs on water?
At the core of Mirai, hydrogen from the fuel tank and air entering from the intake grille meet in the Fuel Cell Stack. There, a chemical reaction involving the oxygen in the air and hydrogen creates electricity—powering Mirai. In the end, the only by-product is water.
Why don t we use water engines?
The released energy could then drive a piston or run a motor and move the car. Here’s the problem, Cheng says: “A water molecule is very stable.” The energy needed to separate the atoms is greater than what you get back — this process actually soaks up energy instead of giving it out.
Can Toyota Mirai run on gas?
Only Answer. The Mirai is a hydrogen-powered fuel cell vehicle that must be fueled at hydrogen stations conforming to the latest Society of Automotive Engineers (SAE) hydrogen fueling interface protocol standards or laws that may supersede such SAE standards.
What are 3 disadvantages of hydrogen fuel?
Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.
Does the Toyota Mirai runs on water?
At the core of Mirai, hydrogen from the fuel tank and air entering from the intake grille meet in the Fuel Cell Stack. There, a chemical reaction involving the oxygen in the air and hydrogen creates electricity—powering Mirai. In the end, the only by-product is water.
How does Toyota water engine work?
The whole setup is a self-contained Marvel of engineering efficiency obviating. The need for intricate refueling stations or external storage.
