Fuel cells are considered promising substitutes for environmental friendly and renewable energy due to their high energy density, and relatively low operating temperature. However, the high cost, low electrocatalytic activity and stability of common Pt catalyst in used fuel cells. To solve these problems, many efforts have been attempted with various methods. Functionalization catalyst support of electrode by modifying functional groups is one of the methods. Especially in the direct methanol fuel cells(DMFCs), the platinum catalyst of the functionalized carbon nanotube is nanoparticles and has wide dispersion, so that methanol oxidation generates on a large surface, Therefore higher performance is expected due to the interaction of the surface-modified carbon nanotube and graphene. As described above, the synthesis of a composite material based on the modified carbon nanotube support can be extensively applied as an appropriate research topic as a catalyst support for a fuel cell. |
