Abstract
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.
