摘　　要：直接甲酸燃料电池(DFAFC)中Pd阳极催化剂对甲酸氧化具有很好的电催化活性,但电催化稳定性较差,因此,对Pd催化剂电催化活性和稳定性的影响原因和机理的研究已经成为DFAFC阳极催化剂的研究重点,本文综述了DFAFC中Pd催化剂和Pd基复合催化剂的研究和发展概况.主要介绍了Pd催化剂的优缺点、稳定性及提高稳定性的方法和机理等,为Pd催化剂和Pd基复合催化剂的实际应用奠定基础.The electrocatalytic activity of the Pd anodic catalyst in direct formic acid fuel cell（DFAFC） for the formic acid oxidation is excellent,while its electrocatalytic satability is poor.The reason and mechanism of the excellent electrocatalytic activity and the poor electrocatalytic stability of the Pd/C catalyst have become an important investigation area of the anodic Pd catalyst in DFAFC.This paper mainly summarizes the situation of research and development of anodic Pd catalyst and Pd-based composite catalysts in DFAFC.The advantages and disadvantages of the Pd catalyst,the mechanisms of the poor electrocataltic stability of the Pd catalyst,the methods and the mechanism of the increase in the electrocataltic stability of the Pd catalyst are reviewed.
