Abstract

Key findings

  • The artificial photo-assisted microbial electrolysis cell (AP-MEC) showed a significant increase in hydrogen production compared to a traditional MEC.
  • The AP-MEC was able to produce hydrogen from wastewaters with high acidity and salinity, making it a promising technology for wastewater treatment and bioenergy production.
  • The study demonstrated the potential of AP-MEC for large-scale biohydrogen production, with implications for renewable energy and sustainable wastewater management.
