摘要

This study aims to develop proton exchange membranes that can be effectively utilized in energy systems like fuel cells, batteries, etc. These systems play an important role in developing green energy solutions for the sustainable environment. This research mainly focuses on fabricating various proton exchange membranes using different polymers and nanomaterials. The aim was to fabricate proton exchange membranes that can be used in energy systems such as fuel cells. Incorporating SPEEK and metal organic framework has enhanced the membranes water uptake and ion exchange capacity. The functionalized polymers showed higher proton conductivity when incorporated in different matrices. In contrast, the membranes showed lesser conductivity when added together in the same matrix. The PES/SPEEK/MIL-100(Fe) have achieved highest proton conductivity of 6.324 × 10–5 S/cm respectively, due to the presence of sulfonic acid group and the proton conductive nature of MIL-100(Fe). The chemical stability of membranes has reduced upon addition of SPEEK and MIL-100(Fe). Overall, PES/SPEEK/MIL-100(Fe) demonstrates significant potential to enhance proton exchange membrane performance.
