PROMOTIONAL EFFECT OF ORDERED MESOPOROUS CARBONS SUPPORTED CATALYSTS FOR IMPROVED FUEL CELL PERFORMANCE

摘要

Considering the commercialization of fuel cell systems, it is crucial to decrease the cost of their platinum-based catalysts by increasing the utilization of catalysts. For this purpose, supported catalysts have attracted much attention. As a support material, porous carbons generally need large pore sizes for the formation of triple-boundary phase, a large surface area for high dispersion of the catalysts, high electrical conductivity for providing electrical pathways, and electrochemical stability for long-term operation. In this regard, ordered mesoporous carbons (OMCs) with large pores offer the advantages of high surface area, tunable pore size, and interconnected pores.
