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
Fuel Cells 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
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 - Wiley Online Library
Fuel Cells - From Fundamentals to Systems publishes on all aspects of fuel cells, ranging from their molecular basis including theory and with molecular processes at catalyst surfaces and microscopic processes in membranes to their application in systems such as power plants, road vehicles and power sources in portables.

Fuel Cells | Hydrogen and Fuel Cells | NREL
What is a fuel cell? A single fuel cell consists of an electrolyte sandwiched between two electrodes. Bipolar plates on either side of the cell help distribute gases and serve as current collectors. Depending on the application, a fuel cell stack may contain a few to hundreds of individual fuel cells layered together.

Fuel cells: A technical, environmental, and economic outlook
A fuel cell consists of an anode, cathode, and an electrolyte that facilitates ion transfer while preventing direct mixing of reactants. Two bipolar plates are also present, ensuring smooth delivery of fuel and oxidant to the electrodes and managing thermal energy within the fuel cell.

Fuel Cells Information, Facts, and Technology | National Geographic
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.

Fuel Cells - Definition, Types, Advantages, Limitations
A fuel cell is an electrochemical cell that uses an electrochemical process to create electrical energy from fuel. To keep the processes that generate electricity going, these cells need a constant supply of fuel and an oxidising agent (usually oxygen).

Fuel Cells: Types and Applications - discoverengineering.org
Explore the various types of fuel cells, their working principles, and diverse applications in industries like transportation, power generation, and portable devices.

What is Fuel Cell? Definition, Construction, Working, Diagram, Types ...
A fuel cell is an electrochemical device that converts chemical energy from a fuel (typically hydrogen) and an oxidizing agent (such as oxygen) directly into electrical energy, with water and heat as by-products.
