Hydrogen Production by Microbial Electrolysis Using Nickel and Platinum Deposited EPPG Electrodes

Acelya Secer


In this study nickel and platinum deposited edge plane pyrolized graphite (EPPG) electrodes were used in microbial electrolysis for high yield hydrogen production. EPPG electrodes were used as working electrode (anode) and metal deposited EPPG electrodes were used as cathode. 2.0 g/L glucose was used in the electrolyte as substrate, and Shewanella oneidensis MR-1was used as exoelectrogenic bacteria. The most effective cathode material was found to be Pt-deposited EPPG. The optimum electrolysis potential for maximum hydrogen production was determined as 0.7V. Maximum hydrogen yield was found as 2.44 mol H2/mol glucose at optimum conditions with Pt-deposited EPPG cathode.
