| 摘要 |
一种含磺酸化聚芳香醚高分子之燃料电池触媒层结构及其制造方法，该制造方法系先提供至少一种磺酸化聚芳香醚高分子；再使该磺酸化聚芳香醚高分子与一触媒成份混掺并调配成一触媒浆液；及将该触媒浆液以涂布方式成膜并乾燥处理成为一电极触媒层。在该电极触媒层中，该磺酸化聚芳香醚高分子所占重量比为5wt%至50wt%。该电极触媒层之磺酸化聚芳香醚高分子可提供良好之热稳定性、玻璃转移温度、化学耐受性、机械特性，并可有效防止水的渗透，及降低质子传递的损失；且制程简单有利于缩短制造过程及降低制造成本。; 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 relatively simple process to shorten the manufacture and lower the cost thereof. |
