| 摘 要： | 测试阳极液和阴极液的pH值和电导率的变化情况, 分析微生物燃料电池(MFC)的产电过程和能量利用情况, 为改善MFC的性能提供理论依据。试验结果表明: 随着MFC的运行, 阳极液的pH值和电导率呈现下降的趋势, 阴极液的pH值和电导率呈现上升的趋势, 阴极液的pH值比阳极液的pH值大约高0.30?0.50, 阳极液和阴极液的平均电导率变化不大。MFC稳定运行时, 欧姆内阻为29.69 Ω, 极限电流为2.69 mA, 最大输出功率约为0.8 mW, 对应的内阻约为95.72 Ω。铁氰化钾的质量传输是极限电流的限制性因素。能量分析发现, MFC阳极液中91.1%的葡萄糖被其他微生物消耗, 仅有8.9%的葡萄糖用来发电; 而用来发电的葡萄糖的88.5%的能量转化为其他形式的能量, 仅有11.5%的能量转化为电能。

| Abstract: | The pH and ionic conductivity change of the anode and cathode solution was tested,and producing electricity process and energy utilization were analyzed to provide a theoretical basis for im-proving the MFC performance in this paper.Experimental results show as follows:The pH and ionic conductivity of the anode solution decreased,while that of the cathode solution increased with the MFC operation,and the latter was higher than the former by about 0.30-0.50 unit finally,while the average ionic conductivity o... |
