Metal–organic frameworks (MOFs) are often used as proton conductor fillers to enhance the conductivity of hybrid membranes. It is interesting but still challenging discuss influence molecular morphology and distribution carriers within MOFs on their exchange membranes (PEMs) overall performance. In this work, two types imidazole-loaded conductors were synthesized based MIL-101(Cr), with one containing free imidazole molecules other coordinating Cr-metal sites. Furthermore, series composite (CPM/IM-x CPM@IM-x, x = 1, 2, 3) fabricated using filler a cross-linked poly(vinyl alcohol) (CL-PVA) that contains both hydrophilic hydrophobic structures matrix. The CPM/IM coordinated exhibit significantly enhanced water affinity, stability, ion capacity. This mainly due improving two-phase dispersion, promoting deprotonation, facilitating low-energy-barrier transport, while CPM@IM relatively lower higher activation energy (Ea). Surprisingly, CPM/IM-2 membrane can reach up 2.7 × 10–2 S cm–1 at 85 °C 90% RH, lowest Ea 20.9 kJ/mol. remarkable performance indicates more efficient H+ transportation. Moreover, single-cell power density 89.7 mW cm–2, proving it exhibits high potential application prospects for hydrogen-based fuel cells.
