Abstract
The performance of low-cost microbial fuel cell (MFC) employing earthenware separator of different thickness is studied. The earthenware separator composed of red soil blended with montmorillonite; a soil mineral having high cation exchange capacity was used for the study. A comparative study of MFC employing 4 mm (MFC-1) and 5 mm (MFC-2) separator thickness was established where MFC-1 outperformed MFC-2. The dual-chambered MFC with inner anodic chamber and concentric outer cathode chamber showed a maximum power density of 47.77 and 33.44 mW/m2 in MFC-1 and MFC-2, respectively, while fed with synthetic dairy wastewater of chemical oxygen demand (COD) 1920 ± 20 mg/L. A comparatively lesser internal resistance of 71 Ω was observed in MFC-1 while 105 Ω in MFC-2 at maximum COD removal efficiency of 89%. MFC-1 and MFC-2 depicted an open-circuit voltage of 822 and 490 mV, respectively, with 150 Ω external resistance.
