摘要

A proton-conducting polymer membrane comprising at least one polyazole, at least one ionic liquid and at least one compound of the formula (P1) RI4POH  (P1) wherein RI, in each case mutually independently, is a residue which comprises C, O and/or H optionally together with further atoms differing therefrom, wherein two residues RI may optionally be joined to one another. The membrane is in particular distinguished by elevated mechanical stability and elevated conductivity and is therefore in particular suitable as a polymer electrolyte membrane for fuel cell applications.
