Abstract：
PtRu/C elecrtrocataylsts for PEMFC was prepared using reverse micelles method.The reverse micelles system was composed of water,cyclohexane,surfactant SBS and noctanol， the molar ratio of H2O to SBS and the mass ratio of SBS to cyclohexane were chosen as 7 and 0.115,respectively,and KBH4 solution was used as reductant.The performance of PtRu/C catalysts were investigated under a continue runing condition of a single PTMFC.The electrocatalytic activity,stability and CO tolerant ability of catalysts were evaluated by Vt curves and IV chariticristics of PEMFC.The results were compared with the commercial PtRu/C catalyst(JM Corporation).
