Pd nanoparticles supported on the WO 3 /C hybrid are prepared by a two-step procedure and the catalysts are studied for the electrooxidation of formic acid. For the purpose of comparison, phosphotungstic acid (PWA) and sodium tungstate are used as the precursor of WO 3 . Both the Pd-WO 3 /C catalyst
In order to improve the catalytic activity and stability of the anodic Pd catalyst for a direct formic acid fuel cell, vanadium ions in very low concentration were introduced to the electrolyte. It was discovered that the electrooxidation of formic acid could be promoted greatly by addition of trace
