Abstract

Pt/C is widely used as a PEFC electrocatalyst. However, Pt detachment and aggregation due to carbon corrosion can occur. Therefore, the conventional Pt/Celectrocatalysthas a difficulty in durability.Our research group have developed Pt/SnO2/VGCF-H electrocatalystsand achieved both high catalyticactivity and high voltage-cycle durability. In this study,we have focusedon PtxCoyalloying anddevelopedPtxCoy/Nb-SnO2/VGCF-H electrocatalystsin order to achieve higher oxygen reduction reaction (ORR)activity. XRD measurementsexhibited alloying of PtxCoybut not reduced SnO2. In addition, half-cell measurements revealedthat a high ORRactivity due to possible PtxCoyalloyinghas been achievedafterperforming the proper heat treatment.
