NOVELTY - A fuel cell comprises a porous metal coating (60) comprising element(s) from the periodic table of elements and which has an atomic number less than 75, and which is positioned at least in partial covering relation relative to the outwardly facing surface of a gas diffusion layer (50).    USE - Used as fuel cell.    ADVANTAGE - The invention effectively reduces contact resistance and resulting equivalent series resistance, and causes a resulting constant current output. It operates at less than 300degreesC, and provides constant electrical current, and constant contact resistance across a wide range of pressure including pressures, which would merely be attributed as sealing pressure. Substantial cost savings can be realized in designing and manufacturing fuel cells. Thus, reduces the relative cost/W to produce electrical power, and makes fuel cells a better option for various commercial applications.    DETAILED DESCRIPTION - A fuel cell comprises an electrode (20) positioned in ion exchange relation relative to an ion exchange membrane (12); a gas diffusion layer borne by the electrode and having an outwardly facing surface; a porous metal coating comprising element(s) from the periodic table of elements and which has an atomic number 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 (80) forcibly disposed in ohmic electrical contact with the porous metal coating.
