An improved electrode assembly for a fuel cell with a gaseous reactant comprises an active layer and a backing layer adhered to the active layer, in which the active layer comprises a catalyst, a matrix polymer and an ion-conducting polymer. The matrix polymer can form a porous polymer matrix in which the ion-conducting polymer is disposed. The backing layer comprises a hydrophobic polymer and a porous composite. A fuel cell stack can include one or more of the improved electrode assemblies.
