A membrane electrode assembly comprising a composite membrane having a first major surface area and a second major surface area comprising a porous polymeric matrix containing ionically conductive solid and ionomeric binder, at least one protective layer disposed adjacent to the porous polymeric matrix membrane comprising an ionomeric binder and an ionically conductive solid, an anode comprising an oxidizing catalyst adjacent said first major surface area of said composite membrane and a cathode comprising a reducing catalyst adjacent said second major surface area of said composite membrane, and a method for manufacturing the same.
Cette invention concerne un ensemble électrode à membrane dont la membrane est du type composite. Cette membrane présente une première surface principale et une seconde surface principale comprenant une matrice polymère qui comprend un liant solide et ionomère ioniquement conducteur, au moins une couche de protection disposée contre la membrane de la matrice polymère poreuse contenant un liant ionomère et un solide ioniquement conducteur, une anode comprenant un catalyseur d'oxydation contre ladite première surface principal de ladite membrane composite et une cathode comprenant un catalyseur de réduction contre ladite seconde surface principale de ladite membrane composite. L'invention concerne également un procédé de fabrication de cette membrane composite.
