The present invention is directed to ion-conducting, nitrile containing sulfonated polymeric materials formed by the direct polymerization of sulfonated monomers and aromatic nitrile monomers. These nitrile containing sulfonated polymers may be used to form membranes that have application in fuel cell and ion exchange technologies. In particular, the membranes may be used in hydrogen, direct methanol, reformate, and other direct oxidation fuel cells.

L'invention concerne des matériaux polymères sulfonés contenant du nitrile, conducteurs ioniques, formés par la polymérisation directe de monomères sulfonés et de monomères nitrile aromatique. Les polymères sulfonés contenant du nitrile selon l'invention peuvent être utilisés pour former des membranes utilisées dans des piles à combustible et dans des techniques d'échange ionique. Lesdites membranes peuvent être utilisées en particulier dans des piles à hydrogène, des piles à méthanol direct, à reformat ou dans d'autres piles à combustible à oxydation directe.
