???? carbon-supported electrode catalysts in proton exchange membrane fuel cell and method for manufacturing the same

摘要

PURPOSE: An HCMS(hollow core with mesoporous shell) carbon-supported electrode catalyst is provided to improve the performance of a fuel cell due to high catalyst activity compared with Pt-Ru catalyst and Pt catalyst dipped in the existing carbon black. CONSTITUTION: An HCMS(hollow core with mesoporous shell) carbon-supported electrode catalyst comprises 15~84 weight% of a hollow core with mesoporous shell consisting of an inside having macro hollow and an outer surface having mesopore; 15~80 weight% transition metal; and 0.01-5 weight% at least one or two kinds selected from a polyalkylene oxide copolymer and alkyl polyethylene oxide copolymer.
