fuel cell

Hydrogen-powered battery alternative

A fuel cell is a device that generates electricity through a chemical reaction, typically combining hydrogen and oxygen to produce power, heat, and water.

Unlike batteries, fuel cells don't store energy—they convert fuel continuously as long as it's supplied.

Hydrogen fuel cells power some buses and experimental vehicles.

The technology promises clean energy since water is the only byproduct when using pure hydrogen.
