    • The present invention provides a method of manufacturing a membrane-electrode assembly for a fuel cell, in which a binder is spray-coated on a surface of a polymer film, a catalyst slurry is bar-coated on a surface of an electrolyte membrane, bonded on the binder, to form a catalyst electrode layer, a bonded assembly of the electrolyte membrane and the catalyst electrode layer is separated from the polymer film, after a drying process, to obtain a 2-layer MEA, and the thus obtained 2-layer MEAs are used to form a 3-layer MEA or a 5-layer MEA by a hot pressing process. Accordingly, the present methods solve the problems associated with prior art that the loss of catalyst is considerable, since the catalyst slurry is directly spray-coated on the membrane, and the catalyst electrode layer in a solid phase is hot-pressed on both surfaces of the membrane.
    • 本发明提供了制造用于燃料电池的膜 - 电极组件的方法,其中将粘合剂喷涂在聚合物膜的表面上,将催化剂浆料棒涂在电解质膜的表面上, 在粘合剂上形成催化剂电极层,将干燥后的电解质膜和催化剂电极层的接合体与聚合物膜分离,得到2层MEA,得到的2层 使用MEA通过热压法形成3层MEA或5层MEA。 因此,本方法解决了与现有技术相关的问题,催化剂的损耗是相当大的,因为催化剂浆料被直接喷涂在膜上,并且固相中的催化剂电极层被热压在 膜。
