In DFFC systems, there are different optimal points depending on the content of cation ionomer with regard to the cell performance and mechanical cell stability during the cell operation.

Palladium on a carbon support, electron-enriched by hydrogen incorporation to form Pd (Pd-H/C), was synthesized via dimethylamine borane complex at multiple temperatures and used for the oxidation of formate (HCOO -). Physicochemical analysis revealed no significant changes in the Pd-H/C structures, with changes in only the particle size and dispersibility. The electronic effect of H was confirmed by physicochemical and electrochemical analysis and by the comparison of synthesized Pd-H/C with commercial Pd/C. The catalyst synthesized at 0 °C showed best catalytic activity for the oxidation of HCOObecause it possessed the largest electrochemical surface area due to its smallest particle size and best dispersibility.
