Preparation of alloy catalyst by reverse micelle method for the improvement in cathode electrode performance of polymer electrolyte fuel cells

采用反胶束法在碳载体上制备了高度分散的Pt-Fe和Pt-Cu电催化剂纳米颗粒。结果表明，与市售标准样品相比，其氧还原反应的电催化活性较高。当这些电催化剂用作阴极电极时，膜电极组件（MEA）的燃料电池性能得到改善。

The highly dispersed nanoparticles of Pt-Fe and Pt-Cu electrocatalysts on carbon supports were prepared by reverse micelle method. It was found that their electrocatalytic activities for oxygen reduction reaction were fairly high compared with commercially available standard samples. The membrane electrode assembly (MEA) showed improved fuel cell performance when these electrocatalysts were used as cathode electrode.
