影响微生物燃料电池产电性能主要因素分析及其性能测试

Analysis of main factors of the effects microbial fuel cell on performances of electricity production and performance test

微生物燃料电池(MFC)是利用微生物作为催化剂直接从可分解的有机物中提取电能的,它具有处置废弃物与发电的双重功效,是未来理想的产电方式和有机废弃物资源化处置工艺。本研究是在分析微生物燃料电池的工作原理基础上,基于微生物燃料电池机理模型,在MATLAB环境下搭建了MFC的Simulink仿真模型,详细分析了有机负载(流入物中醋酸盐的浓度)和电荷负载(外电阻)对MFC产电性能的影响,针对流入物中醋酸盐的浓度和电荷负载对MFC的输出电压、电流以及功率的影响进行了测试和分析。仿真分析得到,当且MFC的外阻与内阻相等时,MFC能产生电能的功率最大。

Microbial fuel cell （MFC） Simulink model was built in the environment of MATLAB based on the mechanism model of the MFC in this work, the main factors effecting the performance of MFC organic load （concentration of acetate inflow in charge） and load （resistance） are analyzed in detail, the effects of concentration and acetate inflow in charge the load on the MFC output voltage, current and power are tested and analyzed, simulated on MFC, and, when the external resistance and resistance is equal, MFC can produce maximum power.
