    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.

  3. 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.

  4. Jan 12, 2023 · Fuel cells are electrochemical devices that generate electricity directly from a fuel, making them highly efficient and pollution-free. Unlike combustion-based power or batteries, fuel cells involve no combustion or recharging.

  5. Feb 24, 2022 · Fuel cells are cells that directly transform the chemical energy of a fuel cell into electrical energy. Fuels such as hydrogen (H 2 ), carbon dioxide (CO 2 ), methane (CH 4 ), propane (C 3 H 8 ), methanol (CH 3 OH), and others are used to create electrical energy in the cells shown below.

  6. Jun 6, 2016 · A fuel cell is a device that produces electric energy, through a chemical reaction. Fuel cells use a positively charged ion (Hydrogen) and an oxidizing agent (oxygen).

  7. 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.

  8. 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.

  9. Fuel cells are classified primarily by the kind of electrolyte they employ. This classification determines the kind of electro-chemical reactions that take place in the cell, the kind of catalysts required, the temperature range in which the cell operates, the fuel required, and other factors.

  10. 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.
