摘　　要：为获得一种高性能且低成本的新型水系铝电池,本文提出并构建了一种直接铝-过硫酸钠微流体燃料电池。研究了阳极电解液浓度、阴阳极电解液总流速及其流速比、氧化剂浓度对该微流体燃料电池产电性能的影响。结果表明:当阳极电解液浓度为2.00 mol/L,阴阳极电解液总流速为200μL/min,阴阳极电解液流速比为1∶1,过硫酸钠氧化剂浓度为1.5 mol/L时,该直接铝-过硫酸钠微流体燃料电池的产电性能达到最佳,其开路电压为2.56 V,功率密度和电流密度的最大值分别为275 mW/cm^(2)和216 mA/cm^(2),铝阳极的最大比容量密度达到2760 mAh/g。An aluminum-sodium persulfate microfluidic fuel cell(MFC)was proposed and constructed to gain a new aqueous Al-based battery.The effects of anodic electrolyte concentrations,total flow rates,anodic and cathodic electrolyte flow rate ratios and oxidant concentrations on the cell performance were investigated.The experimental results show that the performance of the MFC reaches to the best when the anodic electrolyte concentration is 2 mol/L,the total flow rate is 200μL/min,the flow rate ratio of anodic and cathodic electrolyte is 1∶1,and the sodium persulfate concentration is 1.5 mol/L.The open-circuit voltage of the MFC is 2.56 V,and the peak power density and limiting current density is 275 mW/cm^(2) and 216 mA/cm^(2),respectively.The maximum Al specific capacity reaches 2760 mAh/g from the constant-current discharge curves under the different current densities.
