Abstract
The effect of methanol concentration on the performances for passive air-breathing direct methanol fuel cell (DMFC) was studied by single cell tests and methanol transfer theory. With the increase of methanol concentration, the Faradic efficiency and energy efficiency were decreased due to the methanol crossover effect. The maximum power density of 13.9 mW/cm2 and a 20-hour stable performance at a discharge current of 60 mA were obtained under the methanol concentration of 4 mol/L. The above results could be attributed to the synergy of methanol transport and methanol crossover.
