In this study, two different methods were studied to prepare Pt-Pd catalysts for direct methanol fuel cells in order to enhance the electrochemical efficiency. The catalysts were compared with simultaneously deposited Pt-Pd and sequentially deposited Pt-Pd. The electrocatalysts contained 20 wt% of metal loading on carbon black and 1 : 2 of Pt : Pd atomic ratio. Electrochemical properties of the catalysts were compared by measuring cyclic voltammetries and average sizes and lattice parameters were measured by transmission electron microscopy images and x-ray diffraction. As a result, sequentially deposited Pt-Pd/C catalysts showed better electrochemical properties than those of simultaneously deposited Pt-Pd/C catalysts.
