It has been observed in this work and previous studies that Pt,Sn alloy surfaces are very effective catalysts for CO electrooxidation, but not for methanol electrooxidation. Since CO,, is postulated to be an intermediate in methanol electrooxidation on Pt alloy surfaces, the relative inactivity of P

The oxidation of submonolayers of Ru and Sn on Pt in sulfuric acid was monitored with ellipsometry. In the presence of methanol the oxides on Ru and Sn disappear but the Pt-oxide is not affected by methanol. This signifies that Ru and Sn are present in their zero valent state during the methanol o
## Direct methanol fuel cell (DMFC) was pioneered by Shell Research in England and Exxon-Alsthom in France during the 1960s and 1970s [1]. DMFC as a kind of proton exchange membrane fuel cell (PEMFC) has been receiving increasing attention because of its advantages of easy transportation, storage
