Abstract
The invention relates to hybrid membranes that are composed of an organic polymer and an inorganic polymer, a method for producing hybrid membranes, and the use of said hybrid membranes in polymer electrolyte membrane fuel cells. The inventive hybrid membranes comprise at least one alkaline organic polymer and at least one inorganic polymer. Said polymers are blended together at a molecular level. The inorganic polymer is formed from at least one precursor monomer when the membrane is produced. The disclosed membranes are characterized in that the same are provided with high absorptivity for doping agents, have a high degree of mechanical and thermal stability in both an undoped and doped state, and feature permanently high proton conductivity.
