Carbon (CDX-975) based Pt electrodes for direct methanol fuel cell applications

Normally, carbon materials, especially, Vulcan XC 72 are used as supports for Pt for the electrodes in fuel cells. The use of CDX 975 (a product of Columbian Chemical Company, Georgia) for support for electrode applications in methanol fuel cell is described here. The effect of the extent of Pt loading and the performance of various electrodes in methanol oxidation reactions has been studied. It is shown that 10% Pt is the optimal loading for electrode applications.
