Abstract
The kinetics of methanol oxidation and oxygen reduction in 0.5 mol/L K 2CO 3 were compared with those in 0.5 mol/L H 2SO 4. Experiments revealed that carbonate media could be more beneficial to direct methanol fuel cell(DMFC).Firstly, both electrode reactions show better performance in the carbonate than in the acid; secondly, materials other than noble metals become possible to be used as the anodic and cathodic catalysts;thirdly, the potential dectease caused by methanol crossover could be depressed by using metal oxide catalysts not stable in acid, such as MnO 2.
