    摘要: A method is provided for making a crosslinked polymer electrolyte, typically in the form of a membrane for use as a polymer electrolyte membrane in an electrolytic cell such as a fuel cell, by trimerization of nitrile groups contained on groups pendant from the polymer. The resulting polymer electrolyte membrane comprises a highly fluorinated polymer comprising: a perfluorinated backbone, first pendent groups which comprise sulfonic acid groups, and crosslinks comprising trivalent groups according to the formula: The first pendent groups are typically according to the formula: —R1—SO3H, where R1 is a branched or unbranched perfluoroalkyl or perfluoroether group comprising 1–15 carbon atoms and 0–4 oxygen atoms, most typically —O—CF2—CF2—CF2—CF2—SO3H or —O—CF2—CF(CF3)—O—CF2—CF2—SO3H.

    摘要: A method is provided for making a reinforced polymer electrolyte membrane, such as may be used in electrolytic cells such as fuel cells, by mixing a sulfonate- or sulfonyl halide-functional polymer with a bisamidine compound and subsequently trimerizing the amidine groups of the bisamidine compound to form triazine linkages. The sulfonyl halide or sulfonate groups may then be converted to sulfonic acid groups, yielding a polymer electrolyte reinforced with a polytriazine.
