Performance Analysis of Microbial Fuel Cells with Different Exoelectrogens at Low Temperature

Abstract:

The aim of the study is to compare different kinds of microbial species for electricity production in the microbial fuel cells (MFCs) at low temperature. Experiments were conducted with single-chambered MFCs and medium anode inoculated with pure culture from activated sludge. Three kinds of exoelectrogens including Klebsiella sp. ALL-1, Shewanella sp. ALL-2 and Enterobacter sp. ALL-3 were used for evaluating their electricity activity. After adding solution into MFCs, the power of density grew from 50 mV to over 530 mV, and finally maintained at about 520+10 mV during the complete cycles. The results showed that MFCs with Enterobacter sp. ALL-3 had higher power and current density, shorter and more stable working circle at same level of voltage producing than other kinds of exoelectrogens. These characteristics made Enterobacter sp. ALL-3 as optimum exoelectrogen for electricity production at low temperature.
