Abstract

Microbial fuel cell based on as-prepared N-doped carbon foam produced 2 times higher power density than the commercial graphite felt.

Key findings

  • The N-doped carbon foam exhibited high surface area and conductivity, facilitating efficient microbial activity.
  • The anode's high porosity and surface area enabled improved mass transport and electron transfer, enhancing overall MFC performance.
  • The MFC based on the N-doped carbon foam anode produced a 2 times higher power density than the commercial graphite felt anode.
