Apr 12, 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.
Fuel cells combine a fuel (usual hydrogen in some form) with an oxidizing agent (usually oxygen). In the hydrogen fuel cell, hydrogen and oxygen react to form water as a by-product. Electrical current is produced when electrons are freed during the process, which is clean, quiet, and more efficient than burning fuels.

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. Learn more about: Hydrogen fuel. Fuel cells.

HOW IT WORKS. www.cafcp.org. FUEL CELL ENERGY POWERS THE CAR! Hydrogen. 1. HYDROGEN (H2) Hydrogen fuel flows into the anode. 2. Electrical Current. ELECTRONS. The movement of electrons generates electricity to power the motor. 3. OXYGEN (O2) Oxygen flows toward the cathode, where it combines with hydrogen to produce water. H20. Tailpipe Emission =
Jan 1, 2014 · Principle of Fuel Cell. Fuel cells can produce electricity and heat simultaneously through an electrochemical reaction using a fuel and an oxidant. Fuel cells can produce electric energy through an electrochemical system composed of two electrodes (anode and cathode) and an electrolyte.
