采用乙二醇还原法制备了碱性直接甲醇燃料电池PdRu/MWCNT阳极催化剂，并考察了其电催化性能。透射电子显微镜(TEM)结果显示，Ru的加入可以改善Pd纳米粒子在碳载体表面的分散性。X射线光电子能谱(XPS)显示，在Ru的作用下，金属Pd的氧化态有所升高。电化学测试结果表明，PdRu/MWCNT催化剂在碱性溶液中对甲醇电氧化反应具有较高的催化活性和较好的抗中毒能力。

PdRu/MWCNT anode catalyst for alkaline direct methanol fuel cells was prepared by the ethylene glycol reduction method, and the electrocatalytic performance was examined. Transmission electron microscopy (TEM) images show that the addition of Ru improves the dispersion of Pd nanoparticles over the surface of the carbon support. X-ray photoelectron spectra (XPS) shows that there is some increase for the oxidation state of Pd due to the existence of Ru. The electrochemical measurement results indicate that PdRu/MWCNT has high catalytic activity toward methanol electroxidation in the alkaline solution and good poison resistance.
