Abstract: This study presents power generation optimization in a dual chambered aerated membrane microbial fuel cell (MFC) with E.coli as biocatalyst at different culture densities (0.5 & 1.0 OD) using sodium acetate as substrate. Optimum parameters werefound as follows: voltage, 783 mV; power density, 222.84 mW/cm2; and coulombic efficiency (CE), 86.56%. CE with sodium acetate as substrate was higher than with fermentable substrate. High CE indicates improved design of dual chambered mediator less aerated membrane MFC for electrical conductance with an application in water remediation.
