Hydrogen energy storage battery car

Could hydrogen fuel cell batteries revolutionize electric vehicles?

Whether Apple is announcing the next big thing in the mobile space or a small startup advancing generative AI, Dave will apply his experience to help you figure out what's happening and why it's relevant to your life. These hydrogen fuel cell batteries could revolutionize how we power our electric vehicles.

Could hydrogen fuel cell electric cars be the future?

Here’s how it works. Toyota is thinking about how we'll power our cars in the future. Fossil fuel, electric, hybrid and now hydrogen fuel cell electric vehicles (FCEVs) are some possible ways to go. Toyota has unveiled its portable hydrogen cartridges that could provide swappable power for future FCEVs at the Japan Mobility Show Bizweek 2024.

How does a hydrogen car work?

Instead, hydrogen cars effectively have their own efficient power plant on board, which converts the hydrogen in the fuel tank into electricity. And this power plant is the fuel cell. In the fuel cell of an FCEV, hydrogen and oxygen generate electrical energy. This energy is directed into the electric motor and/or the battery, as needed.

What is a hydrogen fuel cell car?

"Hydrogen fuel-cell vehicle" sounds pretty exotic, but in reality it's just an electric car that replaces the bulky, heavy and expensive grid-charged battery pack with a relatively small, lightweight and expensive electrochemical system that produces electricity onboard. The fuel cell is the system's power plant.

How is energy stored onboard a fuel cell electric vehicle?

The amount of energy stored onboard is determined by the size of the hydrogen fuel tank. This is different from an all-electric vehicle, where the amount of power and energy available are both closely related to the battery's size. Learn more about fuel cell electric vehicles.

Can hydrogen fuel cells be used as backup power?

There's no transmission, and the car includes regenerative braking to recapture wasted energy as it slows down. The challenge for automotive engineers is that hydrogen fuel cells are happiest at a steady power output. That’s what makes them suitable for backup power use, for instance.
