Abstract
In this study, carbon nanotubes were used as supporter to get high dispersion and high loading of Pt for PEMFC. Thermal oxidation method was applied to carbon nanotubes surface treatment. FT-IR and XPS were used to measure the effect of temperature on functional group. The increased concentration of functional groups was confirmed by XPS analysis, and increased Pt loading and dispersion was also observed by TGA and TEM analysis with increased temperature. Thermal behavior of oxidation is closely related to the manufacture of highly dispersed Pt/MWCNTs. Pt/MWCNTs treatment temperature at $90^{\circ}C$, showed high dispersion and high loading of Pt, and also showed good cell performance.
