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.
Jun 22, 2024 · 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.
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 cathode)—sandwiched around an electrolyte.
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.
Dec 14, 2022 · 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.

Apr 29, 2024 · A hydrogen fuel-cell vehicle (HFCV for short) uses the same kind of electric motor to turn the wheels that a battery-electric car does.
See our comparison of fuel cell technologies to learn more about the advantages and disadvantages of each fuel cell type. Several types of fuel cells exist, classified by the kind of electrolyte they employ, each with its own advantages, limitations, and applications.
Jul 19, 2023 · 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.
The article provides an overview of fuel cells, describing their basic working principles, historical development, characteristics, and applications. The advantages and disadvantages of fuel cells are also discussed.
