With the innovative, potentially game-changing Toyota Mirai coming out later this year, you can bet hydrogen-powered cars are going to be all the rage. Just like when EVs became popular, the question “How do hydrogen cars work?” is sure to be a popular one soon, so here’s a basic rundown.
Hydrogen cars run on hydrogen gas, which is stored in pressure tanks in the vehicle and then passed through a fuel cell stack, where the hydrogen reacts with oxygen to generate electricity. From here, the electricity powers the motor.
Hydrogen cars have an electric battery used to help the car accelerate, but it’s much smaller than the battery in EVs and doesn’t need to be recharged, as regenerative braking and excess electricity from the hydrogen recharge it while driving.
This reaction inside the fuel cell stack releases nothing more than water vapor, so hydrogen cars have zero tailpipe emissions, and the Toyota Mirai has a better mileage range than any zero-emission car on the market at 312 miles. Hydrogen cars are one of our most efficient options, and they’re definitely going to stick around!
