| Microbial fuel cell (MFC) technology is a promising bio-technology that utilizes the microorganism in organic wastes to generate electricity. Although human urine has been identified as a suitable substrate in MFCs, its possible utilization in a soil-based Membrane-less Single Chamber Microbial Fuel Cell (MSCMFC) for constant power generation has, hitherto, not been reported. In this study, a MFC was set up with mud as inoculums in a plastic cylindrical vessel using carbon felt electrodes. It was operated for 19 days (456 hours) without extra substrate. Then, the MFC was treated with human urine (as substrate) four times (Days 19, 24, 32 and 36) each time the MFC output stabilized across external loads. A control MFC (MFCcontrol) was made the same way and... |
