Abstract
<p>The performance of the liquid-feed DMFC system at near-ambient temperature was investigated for mobile applications. The open circuit voltage and the current density at 0.4 V of the liquid-feed DMFC system decreased with the increasing methanol flow rate because of methanol crossover. The open circuit voltage of the liquid-feed DMFC system monotonously decreased with the increasing methanol concentration. At a temperature of 300 K and a methanol flow rate of 0.1 mL/min, the open circuit voltage of 0.58 V at the methanol concentration of 0.5 mol/L decreased to 0.46 V at the concentration of 5 mol/L. Meanwhile, the current density was a maximum at 1.5 mol/L but dropped at the concentration of 0.5 mol/L due to a methanol deficiency.</p>
