The methanol concentration plays an important role in the performance of direct methanol fuel cells(DMFCs). This work aims to establish an effective controlling strategy of methanol concentration for DMFC power system. We combined the methanol conservation equation and the thermal conservation equation to analyze the mass transport process inside DMFC. The concentration strategy was established based on the two parameters, i.e., charge and temperature. The strategy was effective clarified by the relationship of temperature and concentration. By applying the strategy, the DMFC power system realizes stable operation over 420 min. The appropriate methanol concentration of power system range from 0.70 to 0.87 mol/L. This strategy achieves the goal of methanol concentration control and will play a vital role in the DMFC power systems.
