Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new polymer electrolyte membrane which can be used for a variety of purposes owing to its excellent chemical and thermal properties. SOLUTION: The proton-conducting polymer membrane containing polyazole is obtained by a method comprising the following steps: (A) preparation of a mixture comprising polyphosphoric acid, at least one polyazole (polymer A) and/or one or more compounds which are suitable for forming polyazoles under the action of heat according to step (B); (B) heating of the mixture obtainable according to step (A) under inert gas to temperatures of up to 400°C; (C) application of a layer using the mixture from step (A) and/or (B) to a support; and (D) treatment of the membrane formed in step (C) until it is self-supporting (wherein at least one further polymer (polymer B) which is not a polyazole is added to the composition obtainable according to step (A) and/or step (B) and the weight ratio of polyazole to polymer B is in the range from 0.1 to 50).
