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.

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.

A review on the applications of microbial electrolysis cells in anaerobic digestion

Bioresource Technology, 2018
Anaerobic digestion (AD) has been widely used for biogas or biofuel generation from waste treatment. Because a low production rate and instability of AD occur frequently, various technologies have been applied to improvement of AD. Microbial electrolysis cells (MECs), an emerging technology, can convert organic matter into hydrogen, methane, and other ...

Bioelectrohydrogenesis and inhibition of methanogenic activity in microbial electrolysis cells - A review [PDF]

Biotechnology Advances, 2017
Microbial electrolysis cells (MECs) are a promising technology for biological hydrogen production. Compared to abiotic water electrolysis, a much lower electrical voltage (~ 0.2 V) is required for hydrogen production in MECs.

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 the production of biohydrogen in dark fermentation- A review.

Bioresource Technology, 2022
To assess biohydrogen for future green energy, this review revisited dark fermentation and microbial electrolysis cells (MECs). Hydrogen evolution rate in mesophilic dark fermentation is as high as 192 m3 H2/m3-d, however hydrogen yield is limited.
