英文摘要: An air-breathing direct methanol fuel cell (DMFC) is constructed to investigate methanol crossover and water flux by altering flow rate and concentration of methanol solution. The limiting methanol permeation current density through the anode and membrane is measured voltammetrically, which is sensitive to the flow rate and concentration of methanol solution. The performance variation trends are explained by quantitative analysis of water sources at the cathode. Water diffusion from anode along with methanol crossover plays major contribution to water flooding at the cathode, which decreases the air-breathing DMFC performance. The permeated methanol at the cathode places an extra demand for oxygen, and the optimum methanol solution concentration is largely dependent on the required current density and air flow rate.
