CA 2661934

A process for producing a proton-conducting, polyazole-containing membrane, 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 orifice during the production of the membrane, and B) the composition is then consolidated.

L'invention concerne un procédé de fabrication d'une membrane contenant du polyazole, conductrice de protons, selon lequel A) une composition est pressée au travers d'une ouverture à une température comprise entre 25 °C et 300 °C, ladite composition contenant de l'acide polyphosphorique et au moins un polyazole et présentant une viscosité en solution de 10 Pas à 1 000 Pas, mesurée selon DIN 53018 à la température au niveau de l'ouverture pendant la fabrication de la membrane, et B) la composition est ensuite durcie.
