    English: Diagram of a Proton exchange membrane fuel cell. Intended to replace raster version. File size is almost 1.5 times the original GIF file. It probably needs a lot of touching up as well as optimization.

  3. Proton-exchange membrane fuel cell - Wikipedia

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

    Diagram of a PEM fuel cell. Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower ...

  5. Proton-exchange membrane - Wikipedia

    en.wikipedia.org/wiki/Proton-exchange_membrane

    A proton-exchange membrane, or polymer-electrolyte membrane (PEM), is a semipermeable membrane generally made from ionomers and designed to conduct protons while acting as an electronic insulator and reactant barrier, e.g. to oxygen and hydrogen gas. [1]

  6. Membrane electrode assembly - Wikipedia

    en.wikipedia.org/wiki/Membrane_electrode_assembly

    Electro-chemical reaction Diagram of PEM MEA. A membrane electrode assembly (MEA) is an assembled stack of proton-exchange membranes (PEM) or alkali anion exchange membrane (AAEM), catalyst and flat plate electrode used in fuel cells and electrolyzers. [1] [2]

  7. Proton exchange membrane electrolysis - Wikipedia

    en.wikipedia.org/wiki/Proton_exchange_membrane...

    Proton exchange membrane (PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE) [3] that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes. The PEM electrolyzer was introduced to overcome the issues of partial load, low ...

  8. Direct methanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Direct_methanol_fuel_cell

    Direct methanol fuel cells or DMFCs are a subcategory of proton-exchange membrane fuel cells in which methanol is used as the fuel and a special proton-conducting polymer as the membrane (PEM). Their main advantage is low temperature operation and the ease of transport of methanol, an energy-dense yet reasonably stable liquid at all ...

  9. Protonic ceramic fuel cell - Wikipedia

    en.wikipedia.org/wiki/Protonic_ceramic_fuel_cell

    The technology shares the thermal and kinetic advantages [which?] of high temperature molten carbonate and solid oxide fuel cells, while exhibiting all of the intrinsic benefits of proton conduction in proton-exchange membrane fuel cells (PEMFC) and phosphoric acid fuel cells (PAFC). PCFCs exhaust water at the cathode and unused fuel, fuel ...
