In this study, a steady-state bioelectrochemical model was developed to simulate thecorrelation between the acting overpotential and the produced current that is accounting foranode polarization. This study aimed to analyze the performance of a dual-chamberedmicrobial fuel cell (MFC) equipped with two bio-anodes and fueled with real refinery oilysludge having a COD concentration of 13890 mg /L. Anode polarization data revealed amaximum current density of 6.07 A/m3 of the substrate at an overpotential of 1.83 V. Inaddition, the behavior of the experimental measurements revealed the dominance of theohmic losses in the overall anode overpotential compared to activation and mass transferlosses, respectively. On the other hand, the suggested mathematical model was verifiedsignificantly by the obtained experimental data, achieving a determination coefficient (R2)of 0.96. Actual sustainable energy was also obtained using the reductive decrease of anodepotential (RDAP) and it was found that the sustainable energy for this correspondingsystem can be attained when applying 17.6 KΩ as the external resistor.
