Abstract

The invention is a method for forming a solid polymer electrolyte structure comprising: PA1 (a.) forming a mixture of a binder and a plurality of catalytically active, electrically conductive particles; PA1 (b.) forming the mixture into a particle containing film; PA1 (c.) contacting the film with a fluorocarbon membrane in its thermoplastic form; PA1 (d.) contacting the particle-containing film with an electrically conductive, hydraulically permeable matrix, thereby forming a laminate having a membrane on one side, a matrix on another side and a plurality of catalytically active particles therebetween; and PA1 (e.) applying sufficient pressure to the laminate to embed at least a portion of the matrix into the membrane.
