To address the impediments of low power generation of Nafion, which is the main hurdle in the commercialization of microbial fuel cells (MFC), the current study focuses on developing a new PEM for MFC from mild sulfonation of PEKEKK with relatively improved physiochemical properties. In this study, mild post sulfonation of a polyether ketone ether ketone ketone (PEKEKK) has been successfully achieved using 98% H2SO4 at 90°C under reflux. 5%–30% (wt%) of sulfonated PEKEKK (SPEKEKK) loaded polysulfone (PSU) composite membranes were fabricated via a solution casting method. Ingeminating evidence of the sulfonation and structure of sulfonated polymer was proved by 1H NMR peaks integration data and FTIR, respectively. The addition of SPEKEKK to PSU showed significant improvement in conductivity owing to the availability of more protonated sites (SO3H) and water mediated pathways for the conduction of protons. The composite membrane containing 30 wt% SPEKEKK exhibits the highest conductivity of 0.12 S/cm at 90°C. The water uptakes and swelling ratio of the composite membranes are all higher than that of the pristine PSU membrane and show an increasing trend with increasing SPEKEKK content, thus validating the availability of water domains. Meanwhile, the lowest initial decomposition temperatures assigned to sulfonic acid groups and main chain degradation of the polysulfone/polyether ketone ether ketone ketone (PSU/SPEKEKK) composite membranes occurred at ~300°C and ~500°C respectively, which reflects an excellent thermal stability property. The experimental results indicate that the PSU/SPEKEKK membrane has the potential to greatly enhance the efficiency of MFCs.

“…The fossil fuel sources are important to the auxiliary environmental pollution, and climate changes exist in the worldwide which need to discover eco-friendly and renewable alternative fuels [1,2]. Fuel cells are direct conversions of chemical energy into electrical energy, and have advantages such as environmental friendliness, high power density, noiseless manipulation, and low emission of pollutants [3,4,5].…”

This paper focuses on a literature analysis and review of sulfonated polymer (s-Poly) composites, sulfonated organic, inorganic, and organic–inorganic hybrid membranes for polymer electrolyte membrane fuel cell (PEM) systems, particularly for methanol fuel cell applications. In this review, we focused mainly on the detailed analysis of the distinct segment of s-Poly composites/organic–inorganic hybrid membranes, the relationship between composite/organic– inorganic materials, structure, and performance. The ion exchange membrane, their size distribution and interfacial adhesion between the s-Poly composites, nanofillers, and functionalized nanofillers are also discussed. The paper emphasizes the enhancement of the s-Poly composites/organic–inorganic hybrid membrane properties such as low electronic conductivity, high proton conductivity, high mechanical properties, thermal stability, and water uptake are evaluated and compared with commercially available Nafion® membrane.

“…Another serious limiting factor that restricts its application aspect is the production cost and its energy consuming process. Achievement of full application potential of the MFC technology depends on various factors such as anolyte composition, electrodes, nature of microbes, separators and catholyte composition 7 . Significant research has been done on the influence of anolyte composition in MFC performance.…”

In the existing study, the performance of (I2/I3 -) as the efficient redox catholyte for escherchia coli based microbial fuel cell (MFC) was investigated and compared with conventional ferricyanide based system. This studies also examined the effect of applied current density, linear sweep voltammetry, open circuit voltage, discharge capacitance, Impedance, Energy and power density of the microbial fuel cell. Linear sweep voltammetry studies revealed the higher current density (3.3768 mAcm -2 ) for(I2/I3 -)additive owing to its electro-reduction and this value is about 1.5 times higher in comparison to ferricyanide based system.The characteristics of (I2/I3 -)based MFC is attributed to its higher capacitive contribution, high conductivity, and high power, when compared to ferricyanide based MFC. The extreme power density of the MFC fabricated using (I2/I3 -)and ferricyanide additive at the measured current density of 50 µAcm -2 were observed to be 1,140 and 1,670.8303mWm -2 . Among the results, (I2/I3 -) basedMFCperformance displays excessive potential for enlightening the power generation of MFC.
