Creation of an efficient and cost‐effective proton exchange membrane (PEM) has emerged as a propitious solution to address the challenges of renewable energy development. Coordination polymers (CPs) have garnered significant interest due to their multifunctional applications and moldability, along with long‐range order. To leverage the potential of CPs in fuel cells, it is essential to integrate microcrystalline CPs into organic polymers to prepare membranes and avoid grain boundary issues. In this study, we designed and synthesized CPs containing imidazole and sulfonate moieties via gel‐to‐crystal transformation. The integration of CPs into the PVDF‐PVP matrix resulted in superprotonic conductivity in the order of 10‐2 S cm‐1 at room temperature (30 ºC) and 98% RH. The proton conductivity achieved with CP‐integrated composite membrane was 4.69 × 10−2 S cm−1 at 80 °C and 98% RH, the highest among all CP/MOF‐integrated PVDF‐PVP membranes under hydrous conditions. The excellent compatibility of CPs with PVDF‐PVP produced highly flexible membranes with superior mechanical, chemical, and thermal stability. About 25 times higher proton conductivity value was achieved with membrane, compared to intrinsic CPs, at RT and 98% RH. Thus, we present a cost‐effective CP‐integrated mixed‐matrix membrane with superprotonic conductivity and long‐term durability for cutting‐edge fuel cell development.
