| Abstract: | The PtMoNi/C (w =20%) anodic catalyst for direct methanol fuel cell was prepared by the impregnation reduction meth-od; The effects of atomic ratio of different properties of the catalyst were studied; the crystal structure of the catalyst was studied by XRD; The electrocatalytic oxidation of the catalyst for CH3OH was studied by cyclic voltammetry and chronoamperometry curves; The results showed when atomic ratio of Pt: Mo: Ni was 6:2:2 the performance of the catalyst was best. |
