摘　　要：介绍了组合式再生燃料电池基本特点 ,简要回顾了组合式再生燃料电池中双效氧电极催化剂研究现状。利用还原沉积法制备了PtIr/C双效氧电极催化剂 ,对催化剂进行了XRD表征。以三电极体系对催化剂进行了析氧和溶氧双反应的催化活性评价 ,结果表明 :Pt主要催化燃料电池模式下的溶氧反应 。The characteristic of the unitized regenerative fuel cell and the research actuality of the catalysts used for bifunctional oxygen electrode were reviewed briefly. Three PtIr/C catalysts were prepared by reduction and deposition method. And the catalysts were physically characterized by XRD. The catalysts' electrocatalysis performance was examined in three-electrode system. The results showed that Pt mainly catalyzed the oxygen reduction reaction during fuel cell mode, while Ir mainly catalyzed the oxygen evolution reaction during water electrolysis mode.
