    • A fuel cell catalyst layer having sulfonated poly(arylene ether)s and a manufacturing method therefor are provided. The manufacturing method includes steps of: providing at least one type of sulfonated poly(arylene ether)s; mixing the sulfonated poly(arylene ether)s with a catalyst composition to prepare a catalyst slurry; and coating the catalyst slurry to form a film which is dried to be an electrode catalyst layer, in which the weight ratio of the sulfonated poly(arylene ether)s is 5-50 wt %. The sulfonated poly(arylene ether)s in the electrode catalyst layer can provide good thermal stability, glass transition temperature, chemical resistance, mechanical properties, water impermeability, low proton transmission loss, and a relatively simple process to shorten the manufacturing time and lower the cost thereof.
    • 提供具有磺化聚(亚芳基醚)的燃料电池催化剂层及其制造方法。 制造方法包括以下步骤:提供至少一种类型的磺化聚(亚芳基醚); 将磺化聚(亚芳基醚)与催化剂组合物混合以制备催化剂浆料; 并涂覆催化剂浆料以形成干燥成电极催化剂层的膜,其中磺化聚(亚芳基醚)的重量比为5-50重量%。 电极催化剂层中的磺化聚(亚芳基醚)可以提供良好的热稳定性,玻璃化转变温度,耐化学性,机械性能,不透水性,低质子传导损耗,以及缩短制造时间的较简单的工艺, 成本。
