Fuel cell - Wikipedia
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]
Fuel Cells - Department of Energy
A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat.
Fuel cell | Definition, Types, Applications, & Facts | Britannica
2024年12月23日 · fuel cell, any of a class of devices that convert the chemical energy of a fuel directly into electricity by electrochemical reactions. A fuel cell resembles a battery in many respects, but it can supply electrical energy over a much longer period of time.
Hydrogen and Fuel Cell Technology Basics - Department of …
In a fuel cell, hydrogen energy is converted directly into electricity with high efficiency and low power losses. Hydrogen, therefore, is an energy carrier, which is used to move, store, and deliver energy produced from other sources.
Fuel Cell Basics | Department of Energy
Fuel cells can provide heat and electricity for buildings and electrical power for vehicles and electronic devices. Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied.
