【摘要】 简单介绍了直接甲醇燃料电池(DMFC)的优点及目前研究中存在的主要技术问题,即电催化剂特别是阳极催化剂的活性不足和甲醇渗透问题。综述了DMFC使用的几种主要的阴极氧还原电催化剂的研究进展,着重对无定形的过渡金属族合物类电催化剂材料的研究状况进行了评述,认为该类催化材料的抗甲醇性能优良,但活性有待于进一步提高。更多还原

【Abstract】 The advantages and technique obstacles of direct methanol fuel cell(DMFC) in recent investigation were briefly introduced,namely the low activity of anodic electrocatalysts and the permeation of methanol.The research progress in various types of oxygen reduction cathodic electrocatalysts of DMFC was reviewed,especially amorphous transition metal cluster compound.This type of electrocatalysts had good performance of methanol-tolerant,but the activity of catalysis should be improved.更多还原
