钨基催化材料在直接醇类燃料电池中的应用研究

Application of tungsten-based catalytic materials to direct alcohol fuel cell production

直接醇类燃料电池(DAFC)具有能量密度高、携带方便以及环境友好等优点.电极催化剂是改善DAFC性能的关键材料,目前DAFC催化剂要解决的关键问题是提高催化剂的电催化活性、抗CO等中间产物毒化能力以及降低催化剂成本,文中综述了2种钨基催化材料的制备、性能表征及其在DAFC中的应用研究进展,指出了目前钨基复合催化剂需要重点研究的基础问题.

Direct alcohol fuel cell（DAFC） has the advantages of high energy density, convenient packaging and environment friendliness. The key problem of anode catalyst for DAFC is how to improve the catalytic activity of anodic oxidation, and enhance the ability of resistance to CO poisoning and lower the price of catalyst. This paper reviews the synthesis, electric catalytic properties and applications in DAFC of two kinds of tungsten-based catalysts. The existing basic problems of tungsten-based composite catalysts are proposed.
