Abstract:A direct methanol fuel cell with 9cm2 active area consists of Pt-Ru/C anode,Pt/C cathode and Nafion 115 membrane.The effect of operating conditions:methanol solution concentration,oxygen pressure and cell temperature on the cell performances was investigated.The results show that performance of single cell was enhanced by increasing oxygen pressure and cell temperature,and a maximum power density 75 mW/cm2 was obtained in the range of 250-300 mA/cm2 current density,0.2 MPa oxygen pressure,1.0 mol/L methanol concentration and 75 ℃ cell temperature.When cell operating at room temperature,a relatively low,but a stable performance of cell was also observed.
Keywords:DMFC  Pt_Ru/C  Pt/C  Polymer electrolyte  Performance of cell  Polarization curve.
