摘要

The present invention relates to a method for manufacturing an electrode membrane assembly for a fuel cell for forming a nanosurface structure on a polymer electrolyte membrane, and more specifically, to the surface of the polymer electrolyte membrane by plasma treatment of argon, oxygen, CF _4, etc. The result is a simpler process than the conventional electrode membrane assembly (MEA) by forming the same nano surface structure and directly depositing a catalyst particle or catalyst layer for fuel cell using a sputter method on the polymer electrolyte membrane having the nano surface structure. To produce a fuel cell electrolyte membrane, and to form a nano surface structure on a polymer electrolyte membrane that can significantly reduce the amount of catalyst by directly coating a catalyst for a fuel cell on a polymer electrolyte membrane having a large surface area having a nano structure formed thereon. It relates to a method for producing an electrode membrane assembly for a fuel cell.;To this end, the present invention is a plasma treatment using a PECVD method on the surface of the polymer electrolyte membrane for a fuel cell disposed in the chamber while maintaining a pressure range in the chamber for the plasma treatment 1.0 × 10 ^-7 ~ 2.75 × 10 ^-3 Pa. Wherein, the plasma treatment for 1 second to 60 minutes at 100V to -50kV conditions to form a nanostructure having a plurality of grains on the surface of the polymer electrolyte membrane; Plasma surface treatment to support or deposit the catalyst on the surface of the polymer electrolyte membrane having a plurality of nanostructures; It provides a method for producing an electrode membrane assembly for a fuel cell for forming a nano-surface structure on the polymer electrolyte membrane comprising a.;Nanostructure, polymer electrolyte membrane, electrode membrane assembly, fuel cell, hydrophobic, ion exchange membrane, plasma treatment, PECVD, ion beam, catalyst for fuel cell
