Method of forming nanostructured surface on polymer electrolyte membrane of membrane electrode assembly for fuel cell

摘要

The present invention provides a method of forming a nanostructured surface (NSS) on a polymer electrolyte membrane (PEM) of a membrane electrode assembly (MEA) for a fuel cell, in which a nanostructured surface is suitably formed on a polymer electrolyte membrane by plasma treatment during plasma assisted etching in a plasma-assisted chemical vapor deposition (PACVD) chamber, where catalyst particles or a catalyst layer are directly deposited on the surface of the polymer electrolyte membrane having the nanostructured surface.
