Abstract
In this study, we evaluate catalytic activity of Pd/C catalyst that is synthesized by modified polyol method. With such formed Pd/C is used as anodic catalyst for direct formic acid fuel cell (DFAFC) and performances of the DFAFC are measured to verify whether the new catalyst is effective for enhancing DFAFC performance and to determine optimal loadings of the Pd/C needed for obtaining best DFAFC performance. Pd particle distribution of the Pd/C catalyst is analyzed by TEM, while its catalytic activity is estimated by using cyclic voltammogram (CV) as measuring formic acid oxidation reaction and active surface area. As a result of that, the Pd/C catalyst synthesized by modified polyol shows better catalytic activity and DFAFC performance with small loading amount of Pd/C. When loading amount of Pd/C is $1.5mgcm^{-2}$, maximum power density of DFAFC adopting the catalyst is $122mWcm^{-2}$.
