This study aimed to analyze the performance of a dual-chambered<br>microbial fuel cell (MFC) equipped with two bio-anodes and fueled with real refinery oily<br>sludge having a COD concentration of 13890 mg /L. Anode polarization data revealed a<br>maximum current density of 6.07 A/m3 of the substrate at an overpotential of 1.83 V. In<br>addition, the behavior of the experimental measurements revealed the dominance of the<br>ohmic losses in the overall anode overpotential compared to activation and mass transfer<br>losses, respectively. On the other hand, the suggested mathematical model was verified<br>significantly by the obtained experimental data, achieving a determination coefficient (R2)<br>of 0.96. Actual sustainable energy was also obtained using the reductive decrease of anode<br>potential (RDAP) and it was found that the sustainable energy for this corresponding<br>system can be attained when applying 17.6 KΩ as the external resistor.</p> ER -
