METHOD OF PREPARING MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL

摘要

A method for manufacturing a membrane-electrode assembly for a fuel cell is provided to improve performances of a fuel cell by increasing an interfacial adhesion between a polymeric electrolyte membrane and a catalyst layer. A method for manufacturing a membrane-electrode assembly for a fuel cell includes the steps of: (S1) forming a binder layer on at least one surface of a polymeric electrolyte membrane using a composition for forming a binder layer; (S2) transferring a catalytic layer formed on a transfer substrate to the binder layer-formed polymeric electrolyte membrane; and (S3) joining an electrode substrate to the catalyst layer-transferred polymeric electrolyte membrane.
