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.
