A Nafion 117 complex membrane with low Pd content was prepared. It was found that at room temperature the diffusivity of methanol through this membrane was reduced to one fifth of that through bare Nafion 117 membrane. The proton conductivity of the modified membrane was also increased, significantly improving the discharge performance of the direct methanol fuel cell(DMFC).
