  2. Proton-exchange membrane fuel cell - Wikipedia

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

    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 temperature/pressure ranges (50 to ...

  3. High Temperature Proton Exchange Membrane fuel cell

    en.wikipedia.org/wiki/High_Temperature_Proton...

    High Temperature Proton Exchange Membrane fuel cells (HT-PEMFC), also known as High Temperature Polymer Electrolyte Membrane fuel cells, are a type of PEM fuel cells which can be operated at temperatures between 120 and 200°C. [1] HT-PEM fuel cells are used for both stationary and portable applications. [2]

  4. 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] This is their essential function when incorporated into a membrane electrode assembly (MEA ...

  5. Fuel cell - Wikipedia

    en.wikipedia.org/wiki/Fuel_cell

    Fuel cells are classified by the type of electrolyte they use and by the difference in start-up time ranging from 1 second for proton-exchange membrane fuel cells (PEM fuel cells, or PEMFC) to 10 minutes for solid oxide fuel cells (SOFC). A related technology is flow batteries, in which the fuel can be regenerated by recharging.

  6. Membrane electrode assembly - Wikipedia

    en.wikipedia.org/wiki/Membrane_electrode_assembly

    Ruthenium and platinum are often used together, if carbon monoxide (CO) is a product of the electro-chemical reaction as CO poisons the PEM and impacts the efficiency of the fuel cell. Due to the high cost of these and other similar materials, research is being undertaken to develop catalysts that use lower cost materials as the high costs are ...

  7. 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 ...

  8. 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 ...

  9. Mercedes-Benz F-Cell - Wikipedia

    en.wikipedia.org/wiki/Mercedes-Benz_F-Cell

    The F-Cell is a hydrogen fuel cell electric vehicle developed by Daimler AG. Two different versions are known - the previous version was based on the Mercedes-Benz A-Class, and the new model is based on the Mercedes-Benz B-Class. The first generation F-Cell was introduced in 2002, and had a range of 100 mi (161 km), with a top speed of 82 mph ...
