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.
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.
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 are the most energy eficient devices for extracting power from fuels. Capable of running on a variety of fuels, including hydrogen, natural gas, and biogas, fuel cells can provide clean power for applications ranging from less than a watt to multiple megawatts.
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...
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.
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.
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.
A fuel cell is a device that generates electricity through an electrochemical reaction, not combustion. In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water. Fuel cells are used today in a range of applications, from providing power to homes and businesses, keeping critical facilities like hospitals, grocery ...
