For the direct methanol fuel cell, the expensive cost of Pt is one of the most important factors. In this study, various kinds of support were synthesized and chosen for highly dispersed catalysts which need less amount of Pt and show higher activity. A mesoporous carbon was selected as a support which has 5 times larger specific surface area than Vulcan XC-72, a commercial support. Such a large surface area gave an advantage in the dispersion of Pt, but a disadvantage in electric conductivity which could be solved by increasing the carbonization temperature in the preparation of mesoporous carbon. These prepared mesoporous carbons were used as supports of Pt. Among the catalysts, the catalyst using mesoporous carbon carbonized at 1000 ℃ showed better activity than the catalyst using Vulcan XC-72 as a support showing the best activity. From the XRD analysis, the activity was proportional to the dispersion of Pt.
