“…Recently, microbial fuel cells (MFCs) have attracted much attention as a new technology for simultaneous wastewater treatment and electricity production [3,6,7]. MFCs convert the energy stored in chemical bonds in organic compounds to electrical energy through the catalytic reactions by microorganisms.…”

BACKGROUND Proton‐exchange membrane (PEM) has a significant effect on the performance and overall cost of microbial fuel cells (MFCs). In this study, a novel composite PEM is fabricated by compositing sulfonated graphene oxide (SGO) with the Poly(vinylidene fluoride)‐g‐Poly(styrene sulfonic acid) (PVDF‐g‐PSSA) copolymer. The performance of MFCs with these newly prepared composite PEMs as separators was evaluated. A Quartz crystal microbalance with dissipation (QCM‐D) combined with membrane‐coated sensor crystals was used to investigate the biofouling mechanism of PEMs in MFCs at a micro‐perspective. RESULTS The successful sulfonation of GO was confirmed by Fourier transform infrared spectrometry and X‐ray photoelectron spectroscopy. When the SGO loading was 1.0 wt%, the SGO/PVDF‐g‐PSSA membrane had higher water uptake (32.56%), proton conductivity (0.083 S cm−1) and excellent hydrophilicity (contact angle 70.78°) than that of Nafion 117. QCM‐D results further confirmed its better anti‐fouling property vs that of the PVDF‐g‐PSSA, GO/PVDF‐g‐PSSA, and Nafion 117 membranes. Moreover, the MFC working with the SGO/PVDF‐g‐PSSA membrane exhibited the highest maximum power density and best stability of power production after 3 months of operation. CONCLUSION The SGO/PVDF‐g‐PSSA‐1.0 composite PEM can be used as an alternative material to Nafion in MFCs and is conducive to the long‐term stable operation of MFCs. © 2018 Society of Chemical Industry

“…This kind of decreased proton conductivity was due to the addition of excess filler particles and its aggregation that blocked the ionic channel (''blocking effect'') movement of the polymeric membrane [14]. With respect to the cost analysis also, it is worth noting that the cost involved in the preparation of SPEEK composite polymer (approximately 4$/cm 2 ) was much lower when compared to the commercial membrane, Nafion (10$/cm 2 ) [1].…”

“…In general, MFC consists of anode, cathode chamber separated by a separator [1][2][3]. A single chamber MFC consists of anode chamber, separator, and air facing cathode, while a dual chamber MFC consists of anode chamber, separator, and cathode chamber with or without oxidizing agents such as oxygen-, permanganate-, and ferricyanide-based compounds [4].…”

A new class of composite membranes was made based on sulfonated poly ether ether ketone (SPEEK) incorporated with micron-sized sulfonate styrene-crosslinked divinyl benzene-based cation exchange resin particles as fillers with desired properties of higher ion exchange capacity, lower oxygen crossover, lesser mono, and divalent alkali cation transport for microbial fuel cell (MFC) applications. Such cation exchange resin-based composite membranes showed good membrane homogeneity as revealed from SEM images. XRD patterns showed better amorphous nature for the composite membranes with increase in resin loading. FT-IR spectra of composite membranes showed the presence of hydrogen bonding between the sulfonated PEEK and resin. The effects of existence of hydrogen bonding in the properties of membranes such as water uptake, transport of cations other than proton, oxygen crossover, and proton conductivity were discussed. The composite membranes showed one order lesser oxygen mass transfer coefficient (K o ) in the range of 10 -6 cm/s when compared to Nafion membranes. The composite membranes were tested in a single chamber Pt/C-coated air cathode MFC with Escherichia coli as anodic microbial inoculum. With resin, the SPEEK composite membranes showed higher power density value of 410 mW/m 2 for 7.5 % IER ? SPEEK composite membrane compared to that of Nafion (47 mW/m 2 ) and SPEEK (77 mW/m 2 ) membranes with same configuration.
