<P>PROBLEM TO BE SOLVED: To provide functionalized main chain polymers such as polyaryletherketones and polyethersulfones, and to provide polymer electrolyte membrane fuel cells thereof. <P>SOLUTION: The functionalized main chain polymer is used as non crosslinked, covalently crosslinked and/or optionally ionically crosslinked polymer, and especially the covalently crosslinked and/or optionally ionically crosslinked polymer comprises a repeating unit in which the divalent group of aromatic series or heterocyclic aromatic series or an aliphatic compound is connected with oxygen or sulfur. <P>COPYRIGHT: (C)2012,JPO&INPIT |
