Abstract

Abstract:

The promote action of phosphotungstic acid(PWA) in the electrolyte for the electrooxidation of formic acid at the carbon supported Pd(Pd/C) catalyst in the direct formic acid fuel cell(DFAFC) was investigated using the energy dispersive spectromettry(EDS), X-ray diffraction(XRD) and electrochemical techniques. It was found that the adsorbed PWA could promote dehydrogen of formic acid, leading to the acceleration of the oxidation of formic acid at the Pd/C catalyst. Furthermore, the promote action is related to the PWA concentration. When the concentration of PWA is lower than 0.15 mg/mL the promote action increases with increasing the concentration of PWA. However, when the concentration of PWA is higher than 0.15 mg/mL overfull adsorbed PWA would cover too more active points of the Pd/C catalyst, leading to that the promote action of PWA decreases with increasing the concentration of PWA. Therefore, when the Concentration of PWA is 0.15 mg/mL the electrocatalytic performance of the Pd/C catalyst is best for the oxidation of formic acid.
