Abstract

For polymer electrolyte fuel cells (PEFCs), corrosion of the carbon support of electrocatalysts under cathode conditions is one of the important technical issues to solve, for which SnO2 is a promising alternative support material. In this study, Pt/SnO2 electrocatalysts with integrated conductive fillers have been developed, where the fillers act as the backbone and the built-in electron-conductive pathway. Electrochemical activity and durability of such electrocatalysts against voltage cycling between 1.0 and 1.5 VRHE are investigated. This durable electrocatalyst exhibits higher the oxygen reduction reaction (ORR) activity than Pt/SnO2, and comparable ORR activity to that of the standard Pt/C electrocatalysts.
