The anode catalyst for direct methanol fuel cell is Pt-W-Sn/C, and it is prepared through dispersing carbon black in distilled water, adding H2PtCl6, tungstate and stannate, stirring to make the metal salt and H2PtCl6 adsorbed fully; dropping reductant to reduce and deposite until complete reaction; washing with distilled water, filtering and drying to obtain black C carried sanitary Pt-W-Sn catalyst. The catalyst has excellent methanol catalyzing activity and low cost, and its use can lower the cost of direct methanol fuel cell greatly and raise the performance/cost ratio of the cell.
