The carbon material with tailored mesopore size was explored as an electro-catalyst in polymer electrolyte fuel cells (PEFCs). The mesoporous carbon material possesses unique structural characteristics including non-micropores, specific surface area, pore volume and well-developed interconnected mesoporosity. The good characteristics of the mesoporous carbon make it a large efficient catalyst support for PEFCs. The great mesoporous carbon supported PtRu electro-catalyst has demonstrate an improvement in electro-catalytic activity toward cyclic voltammetry in comparison with commercial Vulcan XC72 supported.
