Provided are an aromatic sulfonic acid derivative and a sulfonic acid group-containing polymer, each of which has excellent proton conductivity even under low humidification conditions, while having excellent mechanical strength and chemical stability, and enables a solid polymer fuel cell to achieve high output and excellent physical durability when used therein. This aromatic sulfonic acid derivative has a specific structure and is characterized in that a sulfonic acid group is introduced into more than 50% of all the phenyl groups. This sulfonic acid group-containing polymer is characterized by being obtained by polymerization using the aromatic sulfonic acid derivative, and is also characterized by having a specific structure.
本发明提供了一种芳香族磺酸衍生物和一种含磺酸基团的聚合物,它们即使在低湿度条件下也具有出色的质子传导性,同时还具有出色的机械强度和化学稳定性,可使固体聚合物燃料电池在使用时实现高输出和出色的物理耐久性。这种芳香族磺酸衍生物具有特定的结构,其特点是在所有苯基的 50%以上引入了磺酸基团。这种含磺酸基团的聚合物的特点是通过使用芳香族磺酸衍生物进行聚合而获得,其特征还在于具有特定的结构。
