Microbial fuel cells (MFC) are an emerging technology for wastewater treatment that utilizes the metabolism of microorganisms to generate electricity from the organic matter present in water directly. The principle of MFC is the same as hydrogen fuel cell and has three main components (i.e., anode, cathode, and proton exchange membrane). The membrane separates the anode and cathode chambers and keeps the anaerobic and aerobic conditions in the two chambers, respectively. This review paper describes the state-of-the-art membrane materials particularly suited for MFC and discusses the recent development to obtain robust, sustainable, and cost-effective membranes. Nafion 117, Flemion, and Hyflon are the typical commercially available membranes used in MFC. Use of non-fluorinated polymeric membrane materials such as sulfonated silicon dioxide (S-SiO2) in sulfonated polystyrene ethylene butylene polystyrene (SSEBS), sulfonated polyether ether ketone (SPEEK) and graphene oxide sulfonated polyether ether ketone (GO/SPEEK) membranes showed promising output and proved to be an alternative material to Nafion 117. There are many challenges to selecting a suitable membrane for a scaled-up MFC system so that the technology become technically and economically viable.

“…In another study, synthetic fiber of polybenzimidazole (PBI) is fabricated with different amounts of polyvinylpyrrolidone (PVP) and utilized as PEM in MFC. 79 About 81 % increase in power output and superior COD removal percentage are observed in composite membrane with 70:30 % (PVP:PBI) over pure PBI membrane, indicating the utility of PVP as composite membrane in MFC. Similarly, PBI has O n L i n e F i r s t been fabricated with mesostructure of SB-15 silica as PEM in a long term MFC operation for wastewater treatment.…”

Practical application of microbial fuel cell (MFC), a sustainable energy device, is hampered by low power output. Its principal components i.e. anode, cathode and proton exchange membrane (PEM) are the focus of enhancement and modification in terms of their functional design and material. The anode surface conduciveness as electron sink is crucial to the power output magnitude, while the cathode electrode should be reactive for efficient oxygen reduction at tri-phase junction. PEM is solely responsible for unidirectional proton flow concomitantly completing the electrical circuit. Polymeric nanocomposites as electrode modifier improved significantly anode/cathode/PEM functions thus overall MFC performance. The review highlights the progress made in polymer-based modifications to anode, cathode and PEM material and function between year 2014 to 2019. The effects to biocompatibility, surface area, internal resistance, electrochemical activities, environmental sustainability, and overall MFC performance are discussed.

“…In most cases, Nafion-type perfluorosulfonic proton exchange polymeric membranes [ 175 , 176 ] are used as a partition, which have good stability under various operating conditions and have become something of a standard in the creation of BFCs [ 177 ]. As a cheaper alternative, heterogeneous membranes made of polypropylene, polyethersulfone [ 178 ], polybenzimidazole [ 179 ], and polyvinylpyrrolidone [ 180 ] are used.…”

Conductive polymers and their composites are excellent materials for coupling biological materials and electrodes in bioelectrochemical systems. It is assumed that their relevance and introduction to the field of bioelectrochemical devices will only grow due to their tunable conductivity, easy modification, and biocompatibility. This review analyzes the main trends and trends in the development of the methodology for the application of conductive polymers and their use in biosensors and biofuel elements, as well as describes their future prospects. Approaches to the synthesis of such materials and the peculiarities of obtaining their nanocomposites are presented. Special emphasis is placed on the features of the interfaces of such materials with biological objects.
