微生物燃料电池数学模型的建立与仿真分析

Establishment and simulation of microbial fuel cell's mathematical model

微生物燃料电池(Microbial Fuel Cell,MFC)是燃料电池中特殊的一类,它能在微生物的作用下将化学能转化为电能,实现污水处理和产电的双重效果。目前对于MFC的研究多处于实验阶段,由于MFC内部极其复杂,从实验角度准确研究其内部各种现象以及分析运行参数对MFC的影响具有相当大的难度。文章通过集成的生化反应,在Bultler-Volmer表达式以及质量/电荷平衡的基础上,在MATLAB仿真平台下建立了双室MFC系统的数学模型并对其进行仿真分析,具有极大的理论指导意义。

Microbial fuel cell is a promising energy source. It can achieve the dual effects of sewage treatment and electricity production under the action of microbial. At present, the research on MFC mainly still in experimental stage, establishment and simulation of MFC remain scare. MFC involve multidisciplinary knowledge of microbiology, electrochemistry, control and materials science. The effects of operating factor and various intrasystem phenomena are not well understood and it＇s difficult to investigate each parameter for researchers using laboratory experiments. This paper modelled and simulated a two-chamber MFC system based on mathematical expression which has a great theoretical significance on further research.
