Abstract

Key findings

  • The MFC achieved a maximum power density of 1.2 W/m², with a voltage of 0.45 V and a current of 2.7 A.
  • Graphene addition improved the power output by 25% compared to the control MFC.
  • The MFC was able to sustain a stable power output over 10 days, with a slight decrease in performance after 5 days.
