Abstract

Key findings

  • The use of a nickel nanostructured electrode increased the surface area and conductivity of the electrode, leading to improved power output.
  • Modifying the microchannel to increase the residence time of bacteria and substrate improved the efficiency of the fuel cell.
  • The combined use of the nickel nanostructured electrode and microchannel modifications resulted in a 2.5-fold increase in power output compared to the original design.
