Abstract (en)

[origin: WO2009138172A1] Proton-conducting polymer membrane comprising at least one polyazole, at least one ionic liquid and at least one compound of the formula (P1) RI 4POH (P1) where each RI independently of any other is a radical which comprises C, O and/or H and also, if desired, further, different atoms, it being possible if desired for two radicals RI to be connected to one another. The membrane is distinguished in particular by high mechanical stability and high conductivity, and is therefore especially suitable as a polymer electrolyte membrane for fuel cell applications.
