Zwitterion-based proton exchange membranes (PEMs) are attracting attention as next-generation materials due to their excellent water retention and high proton conductivity. In this study, PEMs were fabricated via solution casting, with precise control over composition and crosslinking density to optimize water uptake and swelling ratio. The strong hydrophilicity of the zwitterionic groups enhanced moisture retention and stabilized the proton conduction network. Processing parameters such as temperature, relative humidity, and thermal treatment were tuned to adjust the physical and electrochemical properties of the membranes, resulting in structures well-suited for fuel cell applications. The fabricated membranes are currently being evaluated for proton conductivity and electrochemical stability using electrochemical impedance spectroscopy (EIS) and linear sweep voltammetry (LSV), with the goal of assessing their potential as high-performance PEMs.
