Abstract

Key findings

  • The use of non-precious-metal catalysts in single-chamber tubular microbial electrolysis cells resulted in a 30% increase in hydrogen production compared to traditional precious-metal catalysts.
  • The study found that the optimal catalyst loading was 0.5 mg/cm², which achieved a maximum hydrogen production rate of 1.2 A/m².
  • The microbial electrolysis cells using non-precious-metal catalysts demonstrated improved stability and durability, with a lifespan of 1000 hours compared to 500 hours for traditional cells.
