the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...

The attachment of microorganisms to electrodes is of great interest for electricity generation in microbial fuel cells (MFC) or other applications in bioelectrochemical systems (BES). In this work, a microcosm of the acidic ecosystem of Río Tinto was built and graphite electrodes were introduced at different points. This allowed the study of electricity generation in the sediment/water interfac...

The use of proton exchange membranes (PEMs) in biological fuel cells limits the diversity of novel designs for increasing output power or enabling autonomous function in unique environments. Here we show that selected nanoporous polymer filters (nylon, cellulose, or polycarbonate) can be used effectively in place of PEMs in a miniature microbial fuel cell (mini-MFC, device cross-section 2 cm2),...

Abstract The sediment microbial fuel cell (SMFC) is a new technology that uses exoelectrogenic bacteria and organic compounds to transform chemical energy into electrical energy. application of SMFC gaining popularity since it can simultaneously reduce contaminants in wastewater generate electricity. An performance mainly governed by the kinetics electrodes within cell, which materials make up ...

The high internal resistance (Rint) that develops across the sediment microbial fuel cells (SMFC) limits their power production (~4/10 mW m−2) can be recovered from an initial oil-contaminated (OCS). In anolyte, Rint is related to poor biodegradation activity, quality and quantity of contaminant content in anode material. While on catholyte, depends properties oxygen reduction reaction (ORR),...
