Abstract

A novel durable electrode catalyst of Pt/Ketjen black decorated with SnO₂ nanoparticles (Pt/SnO₂-KB) was prepared for polymer electrolyte fuel cells (PEFCs). The particle size of SnO₂ and Pt in the catalyst is ca. 10 nm and 2 nm, respectively. The activity of Pt/SnO₂-KB for oxygen reduction reaction is almost same as that without SnO₂; on the other hand, the durability as the cathode is excellent.
