Abstract [English]

In this study electricity generation was evaluated in a two chambered microbial fuel cell. Performance of microbial fuel cells using two bacteria, Klebsiella pneumoniae and Bacillus coagulans and using three different electrodes namely graphite blocks, carbon cloth and graphite sheet was studied. The device was operated under anaerobic condition in the anode chamber and parameters were recorded for a period of 48 hours. The performance of MFC was analyzed by the measurement of open circuit voltage, polarization curves, impedance curves and cyclic voltammetry. Among different combinations of electrode tested, carbon cloth electrode produced high power density (80 mW/m2). Graphite block gave much high power compared to sheet. Finally, performance was compared with Shewanellaputrefaciens. The current study explores the applicability of carbon electrode for MFC applications.
