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.
