“…It has been generally observed that the higher the IL content in the sulfonated polymer/IL composite, the higher the anhydrous ionic conductivity of the PEM. However, incorporating ILs at high concentrations usually resulted in poor mechanical performance, and the tensile strengths of the reported sulfonated polymer/IL membranes with considerable conductivities were merely about 10 MPa or lower [26,29,[35][36][37][38][39][40]. In this study, we found that Nafion/BmimBF 4 (60) showed both lower tensile strength (~ 7 Mpa) and poorer strain than those of recast Nafion (Fig.…”

“…Alternatively, the proton conduction in Nafion and other sulfonated polymers can be sustained at temperatures above 150 o C by blending these polymers with non-volatile, thermally stable ionic liquids (ILs) that were reported to have anhydrous ionic conductivities exceeding 10 -2 S cm -1 [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. However, up until now, the validation of sulfonated polymer/IL PEMs in H 2 -O 2 FCs has been disappointing.…”

“…However, up until now, the validation of sulfonated polymer/IL PEMs in H 2 -O 2 FCs has been disappointing. The assembled FCs either failed at the beginning or performed poorly [27][28][29][30][31][32][33][34]. These were ascribed to, in most cases, the poor mechanical strength of the sulfonated polymer/IL blend or composite.…”

“…These were ascribed to, in most cases, the poor mechanical strength of the sulfonated polymer/IL blend or composite. As reported, mixing conventional ILs with a polymer, particularly at high concentrations to achieve sufficiently high conductivity, usually deteriorates the mechanical strength of the polymer membrane significantly, and the resultant PEMs were often too weak to endure the FC operations [27,29,[35][36][37][38][39][40]. On the other hand, the proton transfer numbers (t H ) of these PEMs could be too low.…”

“…This new membrane was shown to deliver 4-folds higher power density than Nafion 117 membrane. Jothy and Dharmalingam [84] showed that a similar material, simple combination of a phosphate based alkylimidazolium ionic liquid in sulfonated poly (ether ether ketone) polymer matrix could be a promising anhydrous PEM. Modifications of these composites with improved performance were also reported by Prabhu and Sangeetha [85].…”

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.

Hydrogen energy as the next‐generation clean energy carrier has attracted the attention of both academic and industrial fields. A key limit in the current stage is the operation temperature of hydrogen fuel cells, which lies in the slow development of high‐temperature and high‐efficiency proton exchange membranes. Currently, much research effort has been devoted to this field, and very innovative material systems have been developed. The authors think it is the right time to make a short summary of the high‐temperature proton exchange membranes (HT‐PEMs), the fundamentals, and developments, which can help the researchers to clearly and efficiently gain the key information. In this paper, the development of key materials and optimization strategies, the degradation mechanism and possible solutions, and the most common morphology characterization techniques as well as correlations between morphology and overall properties have been systematically summarized.
