Abstract

Key findings

  • Biofilm capacitance significantly affects MFC performance, with higher capacitance values leading to improved power output.
  • Mixed culture bacteria exhibit better performance than single-species bacteria in MFCs, with increased power density and reduced internal resistance.
  • Electrochemical impedance spectroscopy (EIS) is a suitable method for analyzing MFC performance and identifying factors influencing biofilm capacitance and mixed culture bacteria.
