Abstract (en)
[origin: WO2004024796A1] The invention relates to proton-conducting polymer membranes containing polyazole. Said polymer membranes are obtained by means of a method which comprises the steps of A) producing a mixture comprising polyphosphoric acid, at least one polyazole, and/or at least one or several compounds that are suitable for forming polyazoles when subjected to thermal treatment according to step B), B) heating the mixture obtained in step A) to temperatures of up to 400 DEG C under an inert gas atmosphere, C) applying a layer of the mixture obtained in step A) and/or B) to a carrier, D) treating the membrane formed in step C) until said membrane is self-supporting, the treatment being done by means of a hydrolysis liquid that contains phosphorus oxyacids and/or sulfur oxyacids.
