Proton-conducting polymer membrane comprising sulfonic acid-containing polyazoles, and use thereof in fuel cells |
| abstract |
The invention relates to proton-conducting polymer membranes which comprise sulfonic acid-containing polyazoles and can be obtained by a method comprising the following steps: A) one or several aromatic and/or heteroaromatic tetra-amino compound/s is/are mixed with one or several aromatic and/or heteroaromatic carboxylic acid/s or the derivatives thereof, which contain at least two acid groups per carboxylic acid monomer, at least some of the tetra-amino compounds and/or the carboxylic acids comprising at least one sulfonic acid group, or one or several aromatic and/or heteroaromatic diaminocarboxylic acid/s, at least some of which contain sulfonic acid groups, is/are mixed in polyphosphoric acid so as to form a solution and/or dispersion; B) the solution and/or dispersion obtained in step A) is/are heated to temperatures of up to 350 °C under inert gas so as to form polyazole polymers; C) a layer is applied to a support by using the mixture according to step A) and/or B); D) the membrane formed in step C) is treated until said membrane is self-supporting. |
