Abstract:
A carbon black sheet with a thin layer of metal nanoparticles is provided by pulse electroplating, which allows metal nanoparticles such as platinum to be uniformly dispersed on a carbon black layer and is very thin, enhancing the efficiency of a metal catalyst such as platinum. The process is also used to form a polymer membrane electrode assembly (MEA) for a fuel cell.
