PEM Membrane Electrode Assembly - MEA

Description:

A membrane electrode assembly (MEA) is the heart of the fuel cell. In a MEA two electrodes sandwich a solid polymer proton exchange membrane. On the anode side of the MEA, a fuel (hydrogen, methanol etc.) diffuses through the membrane and is met on the cathode end by an oxidant (oxygen or air) which bonds with the fuel and receives the electrons that were separated from the fuel. Catalysts on each side enable reactions and the membrane allows protons to pass through while keeping the gases separate. In this way cell potential is maintained and current is drawn from the cell producing electricity.
ElectroChem's membrane electrode assemblies are designed to provide consistent and reproducible performance. Unless otherwise specified, hydrophobic carbon paper ist used as a support for a 20 wt.% Pt/C based electrode on a Nafion™ 115 proton exchange membrane. Operating temperature is between 60 ° - 80 °C.
