Abstract

This study investigates the impact of reactor architecture and biocompatibility of anode material on wastewater treatment and power generation in single-chamber (SC) and dual-chamber (DC) microbial fuel cells (MFCs) by utilizing different bacterial food cultures. Comparison between graphite-coated Cu (composite) and 304L stainless steel (SS) anodes is presented under optimized pH (7.13) and temperature (34 °C). Food cultures, especially buttermilk with an acetic acid substrate, significantly enhanced power density (PD), achieving 2.17 W/m² using composite anode and 1.67 W/m² using SS in SCMFCs. Mixed food cultures raised performance by ~50% achieving 3.31 W/m² and 2.97 W/m² using composite and SS anodes respectively. High chemical oxygen demand (COD) removal rates (>68%) confirm effective wastewater treatment. These findings suggest that macroporous composite anodes can improve microbial compatibility and power output in MFCs, with optimal performance observed at neutral pH and ambient temperatures.
