The direct formate fuel cell (DFFC) have a great attention due to its potential as alternative energy technology as compared other liquid fuel cells.[1] The formate (HCOO-) oxidation in alkaline media on palladium (Pd) catalysts had been investigated by Takamura et al.,[2] many researchers have studied and applied single cell performance. For enhancing oxidation activity of catalyst, Pd catalysts for anode had been deeply studied as a number of approaches from a synthesis of catalyst to fabrication of membrane electrode assembly (MEA).[3] In previous studies, we synthesized Pd-H catalyst due to the characteristic of Pd on a carbon support using reducing agents and reported an enhanced catalytic activity for HCOO- oxidation. We reported that the enhanced activity is due to the electron-enriched Pd caused by the hydrogen (H) incorporation to Pd called to electronic effect.[4,5] In this study, we synthesize Pd based catalyst via boron (B) incorporation. Through physicochemical and electrochemical analysis, we observe Pd-B structure, oxidation state, and enhanced catalytic activity comparing with other Pd based catalysts. References [1] J. Jiang, A.
