    • A compound having the general structure (I), wherein A is a monovalent, divalent, or trivalent aromatic heterocyclic group comprising heterocyclic rings; R , R , and R are divalent fluorinated groups; m, n, and p are 0 to 3, with the proviso that m + n + p is equal to 1, 2, or 3 so that the carbon atoms of the heterocyclic rings are fully substituted by acidic fluorinated sulfonyl-containing groups; q is 0 or 1; Y is -OH, -NH-SO2-R wherein R is a monovalent fluorinated group, -NH-, -NH-SO2-R -SO2-NH-, or -NH-SO2-R -A -R -SO2-NH-, wherein A is a divalent heterocyclic group and R , R , and R are divalent fluorinated groups; and Y and Y are -OH or -NH-SO2-R ; with the proviso that when m and n are each equal to 1, p is 0 to 1, and q is 0, Y is selected from the group consisting of -NH-, -NH-SO2-R -SO2-NH-, and -NH-SO2-R -A -R -SO2-NH-. By compound is meant either a small molecule or a repeat unit of a polymer. The invention also provides a solid polymer electrolyte membrane, a membrane electrode assembly, a gas diffusion electrode, an electrocatalyst coating composition, and a fuel cell.
    • 具有一般结构(I)的化合物,其中A 1是包含杂环的一价,二价或三价芳族杂环基; R 1,R 2和R 3是二价氟化基团; m,n和p为0至3,条件是m + n + p等于1,2或3,使得杂环的碳原子被酸性含氟磺酰基的基团完全取代; q为0或1; Y 1是-OH,-NH-SO 2 -R 4,其中R 4是一价氟化基团,-NH-,-NH-SO 2 -R 5 -SO 2 -NH-或-NH -SO 2 -R 6 -A 2 -R 7 -SO 2 -NH-,其中A 2为二价杂环基,R 5,R 6和R 7为 二价氟化基团; Y 2和Y 3是-OH或-NH-SO 2 -R 4; 条件是当m和n各自等于1时,p为0至1,q为0,Y 1选自-NH-,-NH-SO 2 -R 5 - SO 2 -NH-和-NH-SO 2 -R 6 -A 2 -R 7 -SO 2 -NH-。 化合物是指聚合物的小分子或重复单元。 本发明还提供固体聚合物电解质膜,膜电极组件,气体扩散电极,电催化剂涂层组合物和燃料电池。
