Polyelectrolyte membranes with high conductivity are indispensable in fuel cell applications due to several major drawbacks of commonly used polyelectrolytes. Here, we synthesized a linear polyelectrolyte using a monomer using imide acid with high acidity. Poly(MAFSI-PEG) polymers (PMFP) prepared an electrolyte membrane by dissolving MAFSI and PEGDMA in a solvent and UV-curing. For the fabricated electrolyte membrane, we observed successful fabrication of the material synthesis via FT-IR. The prepared PMFP-4 had a water absorption (WU) of 28%, an ion exchange capacity (IEC) value of 4.2 meq./g, and it was observed that the polymer electrolyte membrane showed excellent performance. Therefore, these polymer electrolyte membranes can be used as effective proton conductive materials for fuel cell applications.
