The electrooxidation of dimethoxymethane (DMM) and Trimethoxymethane (cas 149-73-5) (TMM) was studied at different platinum-based electrocatalysts deposited onto a titanium mesh substrate by thermal decomposition of chloride precursors. Half-cell tests showed an increase in oxidation current for the methoxy fuels at the platinum electrode with the alloying of ruthenium and tin. Increase in reaction temperature and reactant concentration showed an increase in current density for the mesh-based anodes similar to carbon-supported catalysts. Single fuel cell tests, employing the titanium mesh anode with PtRu and PtSn catalysts showed maximum power densities up to 31mWcm −2 and 48mWcm −2 for 1.0moldm −3 aqueous solutions of DMM and TMM, respectively at 60°C using oxygen.
