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 کاملAccumulation of intermediate denitrifying compounds inhibiting biological denitrification on cathode in Microbial Fuel Cell
BACKGROUND Bio-cathode denitrifying microbial fuel cell (MFC) is a promising bio-electrochemical system (BES) where both the reactions of anodic oxidation and cathodic reduction are catalyzed by microorganisms. In this nitrogen removal process, a complete biological denitrification from nitrate (NO3 (-)) to molecular nitrogen (N2) was achieved by four reduction steps, forming nitrite (NO2 (-)),...
