METHOD FOR PULSE PLATING CARBON BLACK SHEET WITH METALLIC NANO PARTICLE THIN FILM LAYER, AND CARBON BLACK SHEET&FUEL CELL POLYMER ELECTROLYTE MEMBRANE / ELECTRODE ASSEMBLY PREPARED USING SHEET

The present invention relates to a carbon black sheet with a thin layer of metal nanoparticles by pulse electroplating, which allows metal nanoparticles such as platinum, etc. to be uniformly dispersed on a carbon black layer and is very thin, enhancing the efficiency of a metal catalyst such as platinum, etc., minimizing the amount of the metal used to reduce the manufacturing costs significantly, and realizing a continuous process, and a polymer membrane electrode assembly (MEA) for a fuel cell by using the same.
