Abstract:
One big problem of Direct Methanol Fuel Cell(DMFC)is that methanol is easy to penetrate through the nafion membrane,leading to the decrease in cell performance.Thus,the cathodic catalyst must have good electrocatalytic activity for oxygen reduction and no electrocatalytic activity for methanol oxidation.Therefore,the carbon-supported PdCo catalysts with relatively small particle size and high alloy of Pd and Co were prepared by direct thermal decomposition method of organic Pd salt under different temperatures.It was found that the obtained highly alloyed PdCo/C catalysts have good electrocatalytic activity for oxygen reduction.Among these PdCo/C catalysts,the catalyst synthesized at 200 ℃ showed superior electrocatalytic activity for oxygen reduction.The onset potential of oxygen reduction is 0.69 V.It is mainly due to the synergistic effect between Pd and Co atom.
