WebThese particular type of Electrolyzer MEAs are 3-layer configurations, or Catalyst Coated Membrane (CCM), designed to provide some of the highest efficiencies and purest hydrogen via electrolysis. Custom sizes and configurations are also available with no minimum order quantities and rapid lead times. 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. Meer weergeven The PEM is sandwiched between two electrodes which have the catalyst embedded in them. The electrodes are electrically insulated from each other by the PEM. These two electrodes make up the Meer weergeven At this time most companies manufacturing MEAs specialize solely in high volume production, such as W. L.
