PROCESS FOR PRODUCING A PROTON-CONDUCTING, POLYAZOLE-CONTAINING MEMBRANE

摘要

A process for producing a proton-conducting, polyazole-containing membran e, in which A) a composition is pressed through an orifice at a temperature in the range from 25°C to 300°C, said composition comprising polyphosphoric acid and at least one polyazole and having a solution viscosity in the range from 10 Pas to 1000 Pas, measured to DIN 53018 at the temperature at the or ifice during the production of the membrane, and B) the composition is then consolidated.
