TUNGSTEN OXIDE MODIFIED ORDERED MESOPOROUS CARBON CATALYST FOR FORMIC ACID OXIDATION IN DIRECT FORMIC ACID FUEL CELLS

摘要

Electrocatalysts for the anode electro-oxidation of formic acid in direct formic acid fuel cells (DFAFCs). The Pd-, Pt- or PdPt-based electrocatalysts contain WO₃-modified ordered mesoporous carbon (OMC) as support material. Compositions and ratios of Pd:Pt in the electrocatalysts as well as methods of preparing and characterizing the catalysts and the WO₃-OMC support material.
