Biocatalysts in microbial electrolysis cells: A review

International Journal of Hydrogen Energy, 2016
Abstract Microbial electrolysis cells (MECs) are bioelectrochemical reactors in which chemical energy stored in organic compounds are converted to hydrogen through biocatalytic oxidation by microorganisms. The performance of MECs is highly affected by microbial communities that are impartible parts of this technology.

Microbial community structure of anode electrodes in microbial fuel cells and microbial electrolysis cells

Journal of Water Process Engineering, 2020
This study investigated the microbial community structure on the anode surface of four dual chamber bio-electrochemical systems. These systems were Microbial Fuel Cell (MFC) and Microbial Electrolysis Cell (MEC). The systems were inoculated with activated sludge and operated for electricity generation/hydrogen (H2) production, and phosphorus (P ...

Microbial electrolysis cell with a microbial biocathode

Bioelectrochemistry, 2010
This study demonstrates, for the first time, the proof-of-principle of an MEC in which both the anodic and cathodic reaction are catalyzed by microorganisms. No expensive chemical catalysts, such as platinum, are needed. Two of these MECs were simultaneously operated and reached a maximum of 1.4 A/m(2) at an applied cell voltage of 0.5 V.

Microbial electrolysis cells for hydrogen production

Chinese Journal of Chemical Physics, 2020
Microbial electrolysis cells (MECs) present an attractive route for energy-saving hydrogen (H2) production along with treatment of various wastewaters, which can convert organic matter into H2 with the assistance of microbial electrocatalysis. However, the development of such renewable technologies for H2 production still faces considerable challenges ...

Methanogenesis in membraneless microbial electrolysis cells

Applied Microbiology and Biotechnology, 2009
Operation of microbial electrolysis cells (MECs) without an ion exchange membrane could help to lower the construction costs while lowering the ohmic cell resistance and improving MEC conversion rates by minimizing the pH gradient between anode and cathode.

Responses of Syntrophic Microbial Communities and Their Interactions with Polystyrene Nanoplastics in a Microbial Electrolysis Cell

Science of The Total Environment, 2023
Microbial electrochemical technologies are promising for simultaneous energy recovery and wastewater treatment. Although the inhibitory effects of emerging pollutants, particularly micro/nanoplastics (MPs/NPs), on conventional wastewater systems have been extensively studied, the current understanding of their impact on microbial electrochemical ...
