Microbial fuel cell (MFC) is considered an alternative energy production technology that uses the degradation ability of microbes toward organic matters. The resultant products are electrons that will be transferred to the electrode and flows to cathode of the MFC through an external circuit to...

Algae are efficient biocatalysts for both capture and conversion of carbon dioxide in the environment. In earlier work, we have optimized the ability of Chlorella vulgaris to rapidly capture CO2 from man-made emission sources by varying environmental growth conditions and bioreactor design. Here...

The nano-decoration of electrode with nanoparticles is one effective way to enhance power output of microbial fuel cells (MFCs). However, the amount of nanoparticles used for decoration has not been optimized yet, and how it affects the microbial community is still unknown. In this study,...

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...

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...
