Performance of Single-Chamber Microbial Fuel Cells Based on the Air Cathode of Hydrophobicity of Carbon Black/Polytetrafl uoroethylene Gas Diff usion Layer

Abstract
The eff ect of hydrophobicity of the gas diff usion layer on the performance of a single-chamber microbial fuel cell was
investigated. The R4 (3:1) reactor showed the best performance with a maximum power density of 1431 ± 80.3 mW m −2
and a coulombic effi ciency of 45%. Scanning electron microscopy revealed that the gap between carbon black particles
increased with decreasing PTFE ratio. Electrochemical analysis showed that the activated carbon/stainless-steel mesh/(CB/
PTFE) electrode performed the best with the highest current density of 8.09 A m −2 . High-performance recovery (88%) of the
contaminated electrode was achieved using lysozyme (5%) remediation method. In addition, the R4 (3:1) electrode was the
most suitable choice as an air cathode for SC-MFC, with a fabrication cost of 17.71 $ m −2 . In conclusion, this study provides
valuable insights into the preparation and optimization of air cathodes for MFCs, which can contribute to the development
of future MFC technologies.
