Abstract

Key findings

  • The MMEC showed a maximum hydrogen production rate of 1.5 A/m² at a glycerol concentration of 10 g/L.
  • The cell demonstrated high stability over 100 hours of operation, with a hydrogen production rate of 1.2 A/m².
  • The MMEC outperformed a conventional microbial electrolysis cell (MEC) in terms of hydrogen production rate and stability.
