Method for making an improved solid polymer electrolyte electrode using a binder

摘要

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