The significance of key operational variables to the enhancement of hydrogen production in a single-chamber microbial electrolysis cell (MEC)
Microbial electrolysis cell (MEC) is one of the promising and cutting-edge technologies for generating hydrogen from wastewater through biodegradation of organic waste by exoelectrogenic microbes. In the MECs, the operational parameters, such as applied voltage (Eap), anode surface area, anode-cathode distance, and N2/CO2 volume ratio have a significant impact on the hydrogen yield and producti...
متن کاملHigh hydrogen production rate of microbial electrolysis cell (MEC) with reduced electrode spacing.
Practical applications of microbial electrolysis cells (MECs) require high hydrogen production rates and a compact reactor. These goals can be achieved by reducing electrode spacing but high surface area anodes are needed. The brush anode MEC with electrode spacing of 2 cm had a higher hydrogen production rate and energy efficiency than an MEC with a flat cathode and a 1-cm electrode spacing. T...
متن کاملHydrogen gas production in a microbial electrolysis cell by electrohydrogenesis
Electrohydrogenesis is a bio-electrochemical process where organic material is microbially oxidized to protons and electrons, which in turn are reduced to form hydrogen gas (H2). The reactor in which these reactions occur is termed a microbial electrolysis cell (MEC). The microorganisms that colonize the anode are known as electricigens and behave as biological catalysts, significantly reducing...

متن کاملMicrobial Biohydrogen Production by Rhodobacter sphaeroides O.U.001 in Photobioreactor
Pure strains of Purple Non-Sulfur (PNS) bacteria: Rhodobacter sphaeroides strain O.U 001 was studied for its efficiency to produce biohydrogen using the photofermentative pathways. An annular photobioreactor was being designed aiming the uniform light distribution. In prototype annular photobioreactor, at an initial pH of 6.8±0.2, temperature 32 ± 2 ◦C, inoculum volume 10% (v/v), inoculum age o...
