The biogas upgrading is necessary for its application, and alkali CO2 adsorption is one efficient method. In this study, a coupled system, bipolar membrane electrodialysis (BPMED)–microbial fuel cell (MFC), was proposed for alkali production, which could also realize electricity in situ...

Carbon based multiwalled nanotubes (MWCNT) and nanopowder (CNP) impregnated using conductive epoxy resin on anodic surface were evaluated for bioelectricity generation in single chambered microbial fuel cells in comparison with plain graphite anode (MFCP). The study demonstrated the positive...

The recovery of silver from ammonia chelated silver alkaline waste water, COD removal from acetate waste water and electricity production in a dual chamber bio-electrochemical cell was investigated. The results indicated that pure silver could be deposited on cathode with over 99.9% silver ions...

The urgent need to address the twin problems of the modern world, energy insecurity caused by fossil fuel depletion and climate change caused by global warming from carbon dioxide emission and the greenhouse effect has led to among other things the emergence of fuel cell technology as a green...

Microbial fuel cell (MFC) is an upcoming technology that allows oxidizing organic matter to generate current by microorganism's activity. To render MFCs a cost-effective and energy sustainable technology, low-cost materials can be employed as support for bacteria growth and proliferation. With...

In this article the concept, the materials and the exploitation potential of a photosynthetic microbial electrochemical cell for the production of hydrogen driven by solar power are investigated. In a photosynthetic microbial electrochemical cell, which is based on photosynthetic microorganisms...

Stainless steel mesh (SSM) with four opening sizes (20–80M) were investigated as matrixes of activated carbon air–cathodes in microbial fuel cells (MFCs). The highest power density of 2151±109mWm−2 (at 5.54±0.14Am−2) was obtained using 40M, with a value 45% higher than 1485±18mWm−2...

The influences of hydraulic retention time, temperature and free buffer on the performance of short-cut denitrifying microbial fuel cell were investigated after it was successfully started up using nitrite as the cathodic electron acceptor. The results revealed that a power density of...

The paper focused on the start-up and performance characterisation of a new type of microbial fuel cell (MFC), in which an algae culture was seeded in the cathodic chamber to produce the oxygen required to complete the electrochemical reactions of the MFC, thus circumventing the need for a...

In this work, chemical oxygen demand (COD) and temperature stress-tests on a microbial fuel cell (MFC) were studied. Regarding the temperature stress-test, its value was cyclically modified between 20 and 40°C with stepwise increments of 5°C. The main result was an exponentially increase in...
