Abstract

The development of Pt-free catalyst for anion exchange membrane fuel cells is limited by the sluggish hydrogen oxidation reaction (HOR) at the anode. Previously, the use of CeO ₂ as a catalyst promoter facilitated drastic ennoblement of Pd for the HOR kinetics in base media. However, further optimization and understanding of the Pd–CeO ₂ interaction, surface properties, and their influence on HOR are still needed. In this work, three types of Pd–CeO ₂ /C catalysts are synthesized by a flame-based process, where the Pd–CeO ₂ interface and the HOR activity are improved as compared to catalysts prepared by wet-chemistry processes. The correlation between the Pd–CeO ₂ interaction and the HOR activity is established through comparisons of three types of Pd–CeO ₂ /C synthesized catalysts using electrochemical techniques and X-ray photoelectron spectroscopy.
