Fuel Cell

A device that converts the chemical energy obtained from a redox reaction directly into electrical energy.

The most commonly cited example is the hydrogen fuel cell, in which hydrogen and oxygen are combined, producing electric current and water.

The basic types of fuel cell are:

  • Alkaline Fuel Cell (AFC)
  • Phosphoric Acid Fuel Cell (PAFC)
  • Molten Carbonate Fuel Cell (MCFC)
  • Polymer Electrode Membrane Fuel Cell (PEMFC)
  • Solid Oxide Fuel Cell (SOFC)
Historical Notes
1839 Fuel Cell invented by William Grove.
1932 First successful fuel cell produced by Francis Bacon.
