Metallic plate having, on at least one of its surfaces, a coating comprising conductive material fillers, a polymer used as a binder, and a metal cation absorbing compound, is claimed. Independent claims are included for: (1) a proton-exchange membrane fuel cell comprising at least one metallic plate; (2) a composition for the forming of the coating of the metallic plate, comprising the conductive material fillers, the polymer intended to behave as a binder or its precursor, the metal cation absorbing compound, and a solvent; and (3) preparing the metallic plate, comprising depositing the composition on a metallic plate, by spreading, by spraying, by roller application, or by silk-screening, and drying the metallic plate. |
