Abstract

Key findings

  • The modified anode enhanced the power density of the MFC by 2.5 times compared to the unmodified anode.
  • The optimized operating conditions resulted in a maximum power density of 150 mW/m², which is a significant improvement over previous studies.
  • The microbial communities in the MFC were found to be dominated by Geobacter and Shewanella species, which are known to be involved in the electron transfer process.
