| 摘 要： | 以产电模式菌Geobacter sulfurreducens为研究对象接种两瓶型微生物燃料电池(MFC)阳极室, 利用恒电位仪控制阳极电势, 考察了7种电势条件下MFC的启动期、最大功率密度和阳极生物量的变化情况. 研究结果表明, 当阳极电势为-250, -100和50 mV(vs. SCE)时, MFC启动较快, CV曲线和极化曲线表明, 在这3种电势条件下, MFC产电性能增强, 其中阳极电势为-100 mV时, MFC最大功率密度为1.67 W/m3, 比固定外阻条件下启动的MFC最大功率密度提高了5倍. 控制合适的阳极电势可以使阳极生物量提高2.5~3倍.

| Abstract: | The anode potential is the critical electrochemical parameter in microbial fuel cells(MFCs),which controls both the energy gain for the microorganisms and the output of MFC.This study aimed at elucidating the effects of anode potentials on the performance of electricigen in MFC.The "H" typed MFCs using Geobacter sulfurreducens as the inoculums were operated at different poised anode potentials.The start-up time,maximum power density and biomass were investigated.The results showed that when operated at anod... |
