  Multi-acid polymers for use as a fuel cell membrane, for example, have multi-acid monomers that have an imide base and more than two proton conducting groups. The multi-acid polymers are made by reacting a polymer precursor in sulfonyl fluoride or sulfonyl chloride form with a compound with an acid giving group. One example of a multi-acid polymer is: wherein R is one or more units of a non-SO2F or non-SO2Cl portion of a polymer precursor in sulfonyl fluoride or sulfonyl chloride form.

  例如，用作燃料电池膜的多酸聚合物具有多酸单体，这些单体具有一个酰亚胺基和两个以上的质子传导基团。多酸聚合物是由磺酰氟或磺酰氯形式的聚合物前体与带有酸性基团的化合物反应制成的。多酸聚合物的一个例子是 其中 R 是磺酰氟或磺酰氯形式的聚合物前体的非SO2F 或非SO2Cl 部分的一个或多个单元。

  Multi-acid polymers are produced having the formula R—SO2—NH—R′—(SO3H)n and made from a polymer precursor in sulfonyl fluoride form or sulfonyl chloride form The R is one or more units of the polymer precursor without sulfonyl fluoride or sulfonyl chloride, R′ is the portion of the amino sulfonic acid without the SO3H and NH, n is one or more, and the multi-acid polymer has two or more proton conducting groups. A method of making the multi-acid polymers includes reacting an amino acid having multiple sulfonic acids with a polymer precursor in sulfonyl fluoride form or sulfonyl chloride form in a mild base condition to produce the multi-acid polymer having two or more proton conducting groups.

  R是聚合物前体的一个或多个不含磺酰氟或磺酰氯的单元，R′是氨基磺酸中不含SO3H和NH的部分，n是一个或多个，多酸聚合物具有两个或多个质子传导基团。制造多酸聚合物的方法包括在温和的碱条件下，使具有多个磺酸的氨基酸与磺酰氟形式或磺酰氯形式的聚合物前体反应，生成具有两个或多个质子传导基团的多酸聚合物。
