High performance polymer electrolyte membranes (PEMs) have received wide attention during the past decade, largely owing to the many advantages offered over existing technologies. Broadly speaking, PEMs based energy devices such as fuel cells produce no pollutants, are compact in size, can be easily transported, require minimal resources, with cost and energy efficient in nature. Also PEMs based electrochemical technologies such as electrodialysis, water splitting by electro-electrodialysis (chlor-alkali and other ion substitution reactions), membrane reactor for production and separation of desired products etc are eco-friendly and energy efficient. In all above-mentioned processes, highly charged and conducting PEMs are being used as a separator for electrodes, across which ionic migration occurred. But, generally mass transmission (water or fuel) along with ionic migration due to electro-osmotic drag reduces membrane performance and efficiency. Perfluorinated PEM, known by its trade name NafionTM, is being used world-wide in electro-membrane devices. Despite its attractively proton conductivity and chemical stability, NafionTM is costly and exhibit high mass (water/fuel) transport due to electro-osmotic drag or diffusion.
