Abstract

Key findings

  • The cell achieved a hydrogen production rate of 2.5 times higher than a traditional microbial electrolysis cell.
  • The platinum catalyst-free cathode showed comparable performance to a platinum-catalyzed cathode.
  • The solar-powered system reduced the energy consumption by 70% compared to a traditional microbial electrolysis cell.
