PREPARING METHOD OF MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELL, MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELL PREPARED USING METHOD, AND FUEL CELL SYSTEM COMPRISING SAME

摘要

The present invention relates to a method of manufacturing a membrane-electrode assembly for a fuel cell, and a membrane-electrode assembly for a fuel cell manufactured therefrom, and the fuel cell system comprising the same. Tea impregnation; The first impregnated ion exchange resin membrane surface is second electrically impregnated in a solution containing monomers and anion dopants of the conductive polymer, the electrical conduction comprising an electrically conductive polymer and an anion dopant formed by polymerizing the monomer on the surface of the ion exchange resin membrane Forming a layer; And depositing a catalyst on the ion exchange resin film on which the electrically conductive layer is formed by pulse electroplating to form a catalyst layer.;The membrane-electrode assembly for a fuel cell manufactured by the manufacturing method of the present invention can prevent crossover of fuel and improve the interfacial adhesion between the polymer electrolyte membrane and the catalyst layer, thereby improving battery characteristics when applied to a fuel cell system. .;Fuel cell, membrane-electrode assembly, manufacturing method, electrically conductive polymer, crossover, pulse electroplating.
