ABSTRACT:
A fuel cell is described and which includes an ion exchange membrane; an electrode positioned in ion exchanging relation relative to the ion exchange membrane; a gas diffusion layer borne by the electrode and having an outwardly facing surface; a porous metal coating comprising one or more elements selected from the periodic table of elements and which has an atomic number of less than 75, and which is positioned at least in partial covering relation relative to the outwardly facing surface of the gas diffusion layer; and a current collector forcibly disposed in ohmic electrical contact with the porous metal coating.
