Carbon-supported Pd and PdCo(1:2, 1:1, 2:1 and 3:1) catalysts are synthesized by chemical reduction with NaBH4. Their electrochemical properties are investigated by cyclic voltammetry, chronoamperometry and CO stripping voltammetry. In the cyclic voltammetry, the current density and onset potential of PdCo(1:1)/C are comparable to those of commercial catalysts and the current density increases according to the amount of Co. The onset potential of PdCo(1:1)/C in CO stripping test is negatively shifted by 40mV compared to that of Pd/C catalyst. Thus, PdCo(1:1)/C catalyst has possibility of replacing commercial Pt-based catalysts as an anode catalyst for DEFCs.
