Patent

CA 2607964

The invention provides a polymer blend containing a non-ionic polymer and an ion-conductive copolymer. The polymer blend can be used to fabricate proton exchange membranes (PEM's), catalyst coated proton exchange membranes (CCM's) and membrane electrode assemblies (MEA's) that are useful in fuel cells and their application in electronic devices, power sources and vehicles.

L'invention concerne un mélange polymère contenant un polymère non ionique et un copolymère conducteur d'ions. Ce mélange polymère peut être utilisé pour fabriquer des membranes d'échange protonique (PEM), des membranes d'échange protonique enrobées d'un catalyseur (CCM) et des assemblages d'électrodes membranaires (MEA) utiles dans des piles à combustible. L'invention concerne également l'application de ces membranes et de ces assemblages dans des dispositifs électroniques, des sources d'alimentation et des véhicules.
