Abstract

The subject invention provides new polymer electrolyte membranes composed of polymer blends of pyridine containing aromatic polyethers. The blends exhibit excellent mechanical properties, high thermal and oxidative stability and high ionic conductivities after doping with phosphoric acid. The invention further relates to the preparation of membrane electrode assemblies based on the previous blends and to their use in PEMFCs.
