Hydrogen Fuel Cells

Definition

Hydrogen fuel cells are devices that convert the chemical energy of hydrogen and oxygen into electrical energy through an electrochemical reaction. They produce electricity, heat, and water as byproducts.

Related terms

Electrolysis: The process of using an electric current to split water molecules into hydrogen and oxygen gases.

Renewable Energy: Energy sources that can be replenished naturally, such as solar, wind, or hydroelectric power.

Fuel Cell Vehicles: These are vehicles powered by hydrogen fuel cells instead of internal combustion engines. They produce zero emissions since their only byproduct is water vapor.
