Membrane electrode assembly

Imbedding ELAT with noble metal catalyst allows this carbon cloth to also act as the electrode.

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.

Current service life is 7,300 hours under cycling conditions, while at the same time reducing platinum group metal loading to 0.2 mg/cm2.

[4] At this time most companies manufacturing MEAs specialize solely in high volume production, such as W. L. Gore & Associates, Johnson Matthey, and 3M.

However, there are other companies which produce MEAs, allowing different shapes, catalysts or membranes to be evaluated as well, which include De Nora Tech, Fuel Cell Store, FuelCellsEtc, and many others.
