Abstract

In this paper, the performance of Pt/$WO_3$ and Pt-$WO_3$ electrodes was studied for the direct methanol fuel cell. The characteristics of Pt/$WO_3$ electrode which was prepared by using electrodeposition method was tested with half-cell experiment. The characteristics of Pt-$WO_3$/C electrode which was Prepared by using freeze-drying method was tested with a single cell experiment. The performance of DMFC single cell which was prepared by Pt-$WO_3/C$ and Pt/C showed a current density of $32mA/cm^2$ at $110^{\circ}C$ & 0.3V(0.5mg Pt/$cm^2$).
