Abstract

Conducting polymer coated graphitized active carbon as fuel cell catalysts support improves both the catalytic performance and stability. The PANi coating prevent aggregation and the loss of particles and shows improved long-term stability. X-ray diffraction indicated the Pt/Ru alloy is homogeneous and lacks Pt-core Ru-shell structure. The superior fuel cell performance and better electrocatalytic stability observed for Pt-Ru/P1ACg are attributed from its high degree of Pt-Ru alloy, and high active surface area. This study unveils a new design of durable catalysts by coating a layer of conducting polymer on carbon support which improves catalytical activity, CO tolerance and stability over other catalysts based on the current art.
