摘 要：
减少铂用量和提高铂的抗中毒能力,是直接有机小分子燃料电池实用化过程期待解决的难题,由此而引发了广泛的研究,迄今已先后建立了许多的解决方案.作者也提出了基于氢钼/钨青铜(HxMo(W)O3,0
There are several problems that limit the application of direct small organic fuel cell, including the use of precious platinum and the activity loss of platinum due to the intermediates poisons from the oxidation of small organic molecules. These problems have attracted wide interest and many solutions have been proposed. We have developed a new method to reduce the platinum usage and improve its activity, based on the modifica- tion of platinum with hydrogen molybdenum/tungsten bronze （HxMo（W） O3, 0 〈 x ≤2）. The proton insertion/ desertion into or out of Hx Mo（W） O3 can improve the activity of platinum toward the oxidation of small organic molecule as well as oxygen reduction. On the other hands, the usage of platinum can be reduced by its composite with Hx Mo（W）O3. In this paper, our recent work on the preparation and electrocatalytic activity of platinum modified with Hx Mo（W）O3 was reviewed.
