Abstract

Key findings

  • The hydrophobic Fe–N4/activated carbon air cathode exhibits improved power density and coulombic efficiency compared to traditional cathodes.
  • The enhanced performance is attributed to the hydrophobic properties of the cathode, which reduce oxygen diffusion limitations.
  • The use of activated carbon as a catalyst support further improves the cathode's performance.
