fuel cell

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.

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions.

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.

A fuel cell like this will continue to operate and produce electrical energy as long as a supply of hydrogen and oxygen are available. Fuel cells have an important advantage over all other devices which burn fuel to obtain useful energy: their efficiency.

3 · 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.

What is a Fuel Cell? A fuel cell is an electrochemical power generator. Fuel cells combine hydrogen and oxygen to produce electricity with water and heat generated as byproducts. Fuel cells, like a battery, create energy via an electrochemical process and not combustion.

What is a fuel cell? It is defined as an electrochemical cell that generates electrical energy from fuel via electrochemical reactions. Learn types of fuel cell, working and more here.

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. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or

A fuel cell is a device that uses a source of fuel, such as hydrogen, and an oxidant to create electricity from an electrochemical process. Much like the
