摘要： The present disclosure relates to a method of manufacturing a membrane-electrode assembly capable of reducing consumption of an electrolyte membrane. Specifically, in the present disclosure, a polymer film replaces a non-reaction portion of a conventional electrolyte membrane, so it is possible to prevent waste of a high-priced electrolyte membrane. Consequently, production of membrane-electrode assemblies is improved.

摘要： A method for manufacturing a membrane-electrode assembly (MEA) is provided. In particular, first and second sub-gasket sheets are continuously supplied and an electrode membrane sheet having gaps formed therein so that the amount of an electrolyte membrane used is reduced is discontinuously supplied. Thus, the minimum length of the electrolyte membrane protrudes between sub-gaskets and the electrolyte membrane together with electrode catalyst layers is bonded to the sub-gaskets
