Abstract
The invention is a method for forming a solid polymer electrolyte structure comprising: PA0 (a) heating a fluorocarbon membrane, while it is in its thermoplastic form, to a temperature at which it softens; PA0 (b) contacting a plurality of electrically conductive, catalytically active particles with at least a portion of one face of the membrane, while said membrane is in a softened state; PA0 (c) subjecting the membrane/particle combination to a pressure sufficient to embed at least a portion of the particles into the membrane; PA0 (d) contacting the particulated membrane with an electrically conductive, hydraulically permeable matrix, PA0 (e) subjecting the particulated membrane/matrix combination to a pressure sufficient to embed at least a portion of the matrix into the particulated membrane.
