Outline of Final Research Achievements

The objective of this study was to design and develop Pd-based core-shell nanonetwork catalysts for formate oxidation reaction (FOR) and anode catalyst layers to enhance the performance of direct formate solid alkaline fuel cells (DF-SAFCs). By tuning the synthesis conditions and controlling the Pd structure on the surface of the nanoparticle-connected network, useful findings on the relationship between the catalyst surface structure and FOR activity were obtained. The developed catalyst was applied for the first time to the anode catalyst layer of DF-SAFCs, and the evaluation on the membrane-electrode assembly suggested the usefulness of the support-free hollow capsule catalyst layer.
