“…The composite membranes not only have the advantages of good toughness and easily modified properties from organic membranes, but also have the advantage of high temperature resistant from inorganic membranes. Besides, the introduction of inorganic particles could reduce the methanol permeability . Researchers have found that the inclusion of inorganic fillers (SiO 2 , TiO 2 , and ZrO 2 ) inside the Nafion membrane could enhance the thermomechanical stability and water retention of membrane for operation temperature at above 100 °C .…”

“…found that the proton conductivity of SPEEK membrane with 16 wt % TiO 2 was 15 mS cm −1 at room temperature, about one‐third of the value of the unmodified membrane, and the methanol permeability reduce about 10‐fold. Ayyaru and Dharmalingam added sulfonated TiO 2 (STiO 2 ) treated with sulfuric acid to sulfonated polystyrene–ethylene–butylene–polystyrene (SPSEBS), and found the incorporation of STiO 2 improved the proton conductivity of the SPSEBS membrane effectively. Sulfonated groups on STiO 2 act as vehicle due to its additional acidic sites and creating a path for proton transport, thus the introduction of STiO 2 could improve the proton conductivity of membranes.…”

Sulfonated titanium dioxide (STiO 2 ) was prepared by the reaction of TiO 2 with 1,3-propanesultone. Novel STiO 2 incorporated sulfonated poly(aryl ether sulfone) (SPAES) nanocomposite proton exchange membranes (PEMs) were made by solution casting. Fourier transform infrared, X-ray photoelectron spectroscopy, and proton nuclear magnetic resonance indicated the successful preparation of STiO 2 and SPAES. The thermogravimetric analysis and oxidative stability testing results implied that SPAES/STiO 2 membranes had better stability than pristine SPAES membrane. Meanwhile, the scanning electron microscopy spectra exhibited that the introduction of sulfonated groups on the surface of TiO 2 significantly improved its dispersibility in SPAES matrix. More specifically, SPAES membrane incorporated with 2%STiO 2 exhibited higher proton conductivity (60 mS cm −1 ), lower methanol permeability (2.1 × 10 −7 cm 2 s −1 ) and better proton selectivity (28.0 × 10 4 S s cm −3 ) than that of pure SPAES and SPAES/1%TiO 2 membrane. The SPAES-1%STiO 2 membrane showed better performance in direct methanol fuel cell (DMFC) test than SPAES and Nafion 117 due to the reduction of methanol crossover. From these results, it is evident that SPAES/STiO 2 nanocomposite PEMs have great potential for applications in DMFCs.

Today, the world is on the verge of transformation from fossil fuels to alternative and sustainable renewable sources due to many reasons. Many plausible technologies have been developed of which, energy from biomass and biowaste is a widely accepted choice. In India too, the fuel crisis is imminent and renewable fuel sources are being developed on a large scale to meet energy requirements. However, generation of electricity from biomass and biowaste is a rather unconventional method which is less exploited. The technology that possesses immense future prospective requires collaboration of expertise from various disciplines of science. Here we present a comprehensive view of developments and novel approaches in microbial fuel cell research in Indian scenario in the backdrop of the developments on a global scale. Though the research outputs in India in terms of power density is in par with that on global scale, we lag behind in bringing a collaborative approach.

Summary Organic‐inorganic composite membranes were prepared by introducing silicon dioxide (SiO2) or functionalized SiO2 (ƒ‐SiO2) with various particle sizes into sulfonated poly (arylene ether ketone) (SPAEK) containing pendant groups, and the membrane was manufactured via directly casting which is a cost‐competitive method. The structure and morphology of the composite membranes were confirmed by 1H NMR, FT‐IR, XRD, and FE‐SEM analysis which demonstrated that inorganic nanofillers were successfully introduced. The FE‐SEM surface images showed that SiO2 and ƒ‐SiO2 particles were very well dispersed within the membrane sheets. The water uptake and swelling ratio of the composite membranes including SiO2 or ƒ‐SiO2 almost did not change when compared with the pristine SPAEK membrane. All fabricated membranes demonstrated good thermal/dimensional stabilities, robust mechanical behavior, and excellent proton conductivity. In particular, the SPAEK/ƒ‐SiO2 composite membranes exhibited improved ionic conductivity compared with the pristine membrane at 70% relative humidity (RH) due to hydrogen bonding between ─SO3H groups of functionalized inorganic filler and polymer backbone. Furthermore, the maximum power density of SPAEK/ƒ‐SiO2 reached as high as 273.11 mW cm−2 at 60°C under 70% RH. Therefore, the composite membranes with ƒ‐SiO2 testify to great potential as polymer electrolyte membrane.
