Abstract
Increasing levels of pollution (especially in large cities), the rising cost of oil, and climate change are pushing the scientific community towards more sustainable solutions for the conversion and storage of energy [...].

We report some strategies to enhance the mechanical stability, such as cross linking (XL), or several techniques, including classical casting methods or electrospinning (ES), used to obtain ionomer nanofibers with different morphologies depending on relative humidity (RH); all properties were studied with classical investigations techniques, such as impedance, dynamic mechanical analysis (DMA), fuel cells (FCs) tests, or the new INCA method
Kim et al [3] prepared a series of novel anion exchange membranes (AEMs) with hyperbranched brominated poly(arylene ether sulfone) (Br-HBPAES) and linear chloromethylated poly(phenylene oxide) (CM-PPO) with different weight ratios followed by quaternization with triethylamine, which promoted the ion channel formation
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Ionic conductive polymers are fundamental components of these devices (protonic, anionic, and amphoteric), generally requiring great chemical and mechanical stability; good performance and durability; low permeability to reagents; and excellent characteristics of weight, volume, and current density for several applications from mobile to automotive and co-generation systems.
