ABSTRACT The invention is a method for forming a solid polymer electrolyte structure comprising: (a) forming a suspension of catalytically active, electrically conductive particles and a liquid such as dibromotetrafluoroethane; (b) applying the suspension to at least one side of a fluorocarbon membrane sheet, while said sheet is in its thermoplastic form; (c) removing substantially all of the liquid, leaving the particles on the membrane sheet; (d) pressing at least a portion of the particles into the membrane sheet; and (e) contacting the side of the so-treated membrane having the particles on the surface with an electrically conductive, hydraulically permeable matrix.
