چکیده انگلیسی
Hydrogen represents a promising clean fuel for future applications. The biocathode of a two-chambered microbial electrolysis cell (biotic MEC) was studied and compared with an abiotic cathode (abiotic MEC) in order to assess the influence of naturally selected microorganisms for hydrogen production in a wide range of cathode potentials (from â400 to â1800 mV vs SHE). Hydrogen production in both MECs increased when cathode potential was decreased. Microorganisms present in the biotic MEC were identified as Hoeflea sp. and Aquiflexum sp. Supplied energy was utilized more efficiently in the biotic MEC than in the abiotic, obtaining higher hydrogen production respect to energy consumption. At â1000 mV biotic MEC produced 0.89 ± 0.10 m3 H2 dâ1 mâ3NCC (Net Cathodic Compartment) at a minimum operational cost of 3.2 USD kgâ1 H2. This cost is lower than the estimated market value for hydrogen (6 USD kgâ1 H2).
