摘要(Abstract)：

为了探究不同因素对微生物燃料电池（MFC）电流输出影响，建立了以葡萄糖为底物，硫瑾为电子中介体的微生物燃料电池阳极区域一维动态传质模型。模型方程用MATLAB软件编程求解，考查并分析了微生物、葡萄糖和还原态电子中介体初始浓度与外接电阻值对电池电流的影响，并与实验结果进行了对比。模拟结果表明：与稳态传质模型相比，作者所建立的动态传质模型模拟结果和实验结果能够更好吻合；增加阳极室中微生物初始浓度、葡萄糖初始浓度，还原态电子中介体初始浓度或减小外接电阻值均有利于增加电池电流且模拟结果与实验结果一致；当阳极室中还原态电子中介体的初始浓度为0.1 mmol·L^-1电极表面浓差极化现象对电池电流影响较大，导致模拟数据与实验数据有偏差。该模型可为研究其他复杂模型提供参考。
