Abstract
A carbon-platinum core-shell type catalyst for fuel cells and a method for preparing the same which includes carbon as a core and platinum as a shell which can solve durability-associated problems under proton exchange membrane fuel cells (PEMFC) operation conditions and furthermore tackle manufacturing cost-related problems and process complexity by improving acid resistance through incorporation of a carbon material rather than a transition metal into catalysts.
