Abstract:
Microbial Fuel Cells (MFCs) have attracted considerable attention over the last decade as a sustainable technology for electricity generation. Although, the concept of electricity production from bacteria was conceived nearly a century ago, only recently the technology has been sufficiently improved to make it useful as a method for energy generation. Performances of constructed MFCs with different enriched environmental samples were investigated under batch mode of operation after 24 h of incubation using different cathodic electrolytes and electrodes in mediator-less and with methylene blue as mediator. The maximum power density obtained was 48.85 mW m-2 with graphite rod and 42.59 mW m-2 with copper electrode and current density obtained was 108.57 mA m-2 with graphite rod and 88.01 mA m-2 with copper electrode all obtained with KMnO4 solution.
