## Description

- description: 'Fast proton conduction under anhydrous conditions is pivotal for advancing
    intermediate-temperature (100–300 °C) hydrogen (H2) energy technologies, such
    as fuel cells and electrolysers. However, identifying suitable proton conductors
    for this temperature range remains challenging: the temperature is too high for
    water-mediated transport but too low for defect-driven conduction. Framework materials,
    including crystalline and glassy coordination polymers (CPs) or metal–organic
    frameworks (MOFs) and covalent organic frameworks (COFs), have emerged as promising
    candidates, offering tunable structures and unique pathways for anhydrous proton
    conduction, with some exhibiting “superprotonic-like” conductivity. This review
    covers the fundamental mechanisms and design principles governing proton transport,
    emphasising the roles of structural features, defects, dynamic disorder, and functional
    groups. Emerging materials, including CP/MOF glasses with isotropic structures
    and COFs with aligned one-dimensional nanoscale channels, are highlighted as promising
    candidates. Beyond intrinsic conductivity, we evaluate practical considerations
    essential for device integration, including mechanical processability, thin-film
    fabrication, long-term thermal and chemical stability, and stimuli-responsive
    conductivity. The comparative advantages and limitations of CPs/MOFs, their glass
    derivatives, and COFs are critically analysed. Finally, the review discusses key
    challenges and future directions toward realising stable, high-performance anhydrous
    proton conductors for practical hydrogen energy applications.'
