“…Also, the OsRP is a positively charged redox polymer that facilitates more stable contact with negatively charged bacterial surface structures with the help of strong electrostatic interactions ,. Surface modification of the bioanodes with nanomaterials or mediating and charged polymers like OsRP provides a good adhesion environment and facilitates electron transfer from the bacterial cells to the electrode surface …”

In this work, a carbon felt electrode (CFE) was modified with a multiwalled carbon nanotube‐gold‐platinum (MWCNT−Au‐Pt) hybrid nanomaterial and integrated with an osmium redox polymer (OsRP, [Os(2, 2’‐bipyridine)2(poly‐vinylimidazole)10Cl]Cl) and Gluconobacter oxydans DSM 2343 (G. oxydans) cells. The developed electrode was used as the bioanode in a 5.0 mM K3Fe(CN)6 mediator containing phosphate buffer (pH 6.5) anolyte and combined with a Pt wire cathode in phosphoric acid medium (pH 3.5). As a result, a two chamber microbial fuel cell (MFC) was formed, in which an activated Nafion membrane was used as a proton exchange membrane. The OsRP/G.oxydans/MWCNT−Au‐Pt/CFE based bioanode was electrochemically examined in differently deoxygenated bioanode chambers and additionally the amounts of hybrid nanomaterial and OsRP were optimized. In terms of MFC characteristics, it was found that an anaerobic OsRP/G.oxydans/MWCNT−Au‐Pt/CFE bioanode based MFC had a maximum power density of 32.1 mW m−2 (at 90 mV), a maximum current density of 1032 mA m−2 and a charge transfer efficiency (E%) value of 22.30 (open circuit potential 180 mV).

“…Anodes, from the point of view of exoelectrogenic strains, can be seen as terminal electron acceptors utilized under anaerobic conditions [8]. In this sense, anodes are interfaces connecting the biofilm with the (normally abiotic) cathode electrode (as a terminal electron donor, e.g., for oxygen reduction) by receiving the electrons (liberated from microbial metabolic pathways of organic matter oxidation) and conveying the charge to the external circuit containing (a resistor and) the cathode [9][10][11]. Furthermore, to increase the electrochemical efficiency of a bioelectrochemical system such as MFC in terms of the current production and power output, the total internal resistance of the Figure 1.…”

Development and Application of Supported Ionic Liquid Membranes in Microbial Fuel Cell Technology: A Concise Overview

et al. 2020

View full text Add to dashboard Cite

Membrane separators are key elements of microbial fuel cells (MFCs), especially of those constructed in a dual-chamber configuration. Until now, membranes made of Nafion have been applied the most widely to set-up MFCs. However, there is a broader agreement in the literature that Nafion is expensive and in many cases, does not meet the actual (mainly mass transfer-specific) requirements demanded by the process and users. Driven by these issues, there has been notable progress in the development of alternative materials for membrane fabrication, among which those relying on the deployment of ionic liquids are emerging. In this review, the background of and recent advances in ionic liquid-containing separators, particularly supported ionic liquid membranes (SILMs), designed for MFC applications are addressed and evaluated. After an assessment of the basic criteria to be fulfilled by membranes in MFCs, experiences with SILMs will be outlined, along with important aspects of transport processes. Finally, a comparison with the literature is presented to elaborate on how MFCs installed with SILM perform relative to similar systems assembled with other, e.g., Nafion, membranes.

“…Transfer is, however, not without impediment from electrode overpotentials arising from activation, bacterial metabolism, and mass transport losses . A recent review discussed the various improvements in anode electrode materials to minimize losses incurred by the aforementioned factors and further enhance the performance of MFCs . The biocompatibility of the anode could also be the target of modification, so as to be a conducive, supporting habitat for microorganisms, among others.…”

Amphiphilic Biopolyester‐Carbon Nanotube Anode Enhances Electrochemical Activities of Microbial Fuel Cell

et al. 2019

Hydrophobic bacterial polyhydroxyalkanoates were rendered amphiphilic by grafting with poly(ethylene glycol) methacrylate, followed by compositing with carbon nanotubes. The polymer graft composite as an anode material encouraged superior biofilm surface growth; thus enhancing electrochemical activities in microbial fuel cells and resulting in higher current and power densities. The internal resistance of the cell was greatly reduced due to improved electron transfer from the biofilm to the anode.
