Ordered mesoporous carbon (OMC) has been considered as a promising Platinum catalyst support because of its large surface area, uniform ordered hexagonal mesopores, porous structure and high electrical conductivity. Graphitization of the walls of OMC is vital when the electrical conductivity of the catalyst is the main concern. The objective of this work was to improve the electrical conductivity of the ordered mesoporous carbon (OMC) support by utilizing transition metals such as Ni, Co and Fe to graphitize the pore walls of OMC via catalytic graphitization. Metal modified OMCs have been synthesized following two steps. First step is synthesizing metal modified SBA-15 as a template containing 10wt% transition metals (Ni, Co, Fe) and TEOS as a source of silica followed by calcination. The second step is introducing sucrose as the carbon source into the pores of the silica template followed by carbonization at 900°C and removal of the silica template using hydrofluoric acid. The synthesized Metal modified OMCs were characterized using Brunaeur Emmit Teller (BET) analysis, X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman spectroscopy. Surface area for the metal modified --OMC was found around 1300--1500m 2/g and pore sizes in the range of 3--4nm. The membrane electrode assembly (MEA) was prepared using the synthesized electrocatalyst and was used to evaluate the performance of the catalyst by testing it on the fuel cell test station. The results were compared to that of commercial catalyst.
