  2. Fuel cell - Wikipedia

    en.wikipedia.org/wiki/Fuel_cell

    Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell. 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]

  3. Alkaline fuel cell - Wikipedia

    en.wikipedia.org/wiki/Alkaline_fuel_cell

    The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its British inventor, Francis Thomas Bacon, is one of the most developed fuel cell technologies. Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70%.

  4. Regenerative fuel cell - Wikipedia

    en.wikipedia.org/wiki/Regenerative_fuel_cell

    A regenerative fuel cell or reverse fuel cell (RFC) is a fuel cell run in reverse mode, which consumes electricity and chemical B to produce chemical A. By definition, the process of any fuel cell could be reversed. [1] However, a given device is usually optimized for operating in one mode and may not be built in such a way that it can be ...

  5. Proton-exchange membrane fuel cell - Wikipedia

    en.wikipedia.org/wiki/Proton-exchange_membrane...

    A proton exchange membrane fuel cell transforms the chemical energy liberated during the electrochemical reaction of hydrogen and oxygen to electrical energy, as opposed to the direct combustion of hydrogen and oxygen gases to produce thermal energy. A stream of hydrogen is delivered to the anode side of the MEA.

  6. Unitized regenerative fuel cell - Wikipedia

    en.wikipedia.org/.../Unitized_regenerative_fuel_cell

    A unitized regenerative fuel cell (URFC) is a fuel cell based on the proton exchange membrane which can do the electrolysis of water in regenerative mode and function in the other mode as a fuel cell recombining oxygen and hydrogen gas to produce electricity. Both modes are done with the same fuel cell stack [1]

  7. Fuel cell vehicle - Wikipedia

    en.wikipedia.org/wiki/Fuel_cell_vehicle

    A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
