  2. Solid oxide fuel cell - Wikipedia

    en.wikipedia.org/wiki/Solid_oxide_fuel_cell

    The planar fuel cell design geometry is the typical sandwich type geometry employed by most types of fuel cells, where the electrolyte is sandwiched in between the electrodes. SOFCs can also be made in tubular geometries where either air or fuel is passed through the inside of the tube and the other gas is passed along the outside of the tube.

  3. 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]

  4. 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 ...

  5. 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]

  6. 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 ...

  7. Phosphoric acid fuel cell - Wikipedia

    en.wikipedia.org/wiki/Phosphoric_acid_fuel_cell

    Diagram of a phosphoric acid fuel cell. Phosphoric acid fuel cells (PAFC) are a type of fuel cell that uses liquid phosphoric acid as an electrolyte. They were the first fuel cells to be commercialized. Developed in the mid-1960s and field-tested since the 1970s, they have improved significantly in stability, performance, and cost.

  8. High Temperature Proton Exchange Membrane fuel cell

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

    Higher lifetime of methanol fueled HT-PEM fuel cell system than for DMFC system is possible. Pure fuels or water-fuel mixtures are applicable (depending on fuel cell system design). Use of renewable fuels is possible. Cold storage temperatures below 0 °C are no problem for the fuel cell membrane in contrast to DMFC and LT-PEM fuel cell.

  9. Solid oxide electrolyzer cell - Wikipedia

    en.wikipedia.org/wiki/Solid_oxide_electrolyzer_cell

    SOEC 60 cell stack. A solid oxide electrolyzer cell (SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water (and/or carbon dioxide) [1] by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas [2] (and/or carbon monoxide) and oxygen.
