Abstract

Key findings

  • The bimetallic CuZn catalyst showed improved oxygen reduction reaction performance compared to a commercial Pt/C catalyst.
  • The microbial fuel cell with the CuZn catalyst achieved a higher power density and coulombic efficiency compared to the Pt/C catalyst.
  • The CuZn catalyst was found to be stable and durable over multiple cycles, making it a promising alternative to expensive noble metal catalysts.
