The incorporation of cerium–zinc bimetallic oxide (CeZnOx) nanostructures in sulfonated poly(2,6-dimethyl-1,4-phenylene oxide) (SPPO) membranes holds promise an enhanced and durable fuel cell performance. This investigation delves into the durability efficiency SPPO intercalated with CeZnOx by varying filler loading 1, 2, 3% (w/w). successful synthesis alkali-aided deposition method is confirmed wide-angle X-ray diffraction spectroscopy (WAXS), Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission (TEM), photoelectron (XPS) analyses. CeZnOx@SPPO nanocomposite are fabricated using a solution casting method. intricate interplay interfacial adhesion coupling configuration between three-dimensional sulfonic moieties backbone yields enhancement bound water content within proton exchange (PEMs). constructs simultaneously extensive hydrogen bonding network intertwined transport channels, thereby elevating conductivity (Km). orchestrated reversible redox cycling involving Ce3+/Ce4+ enhances quenching aggressive radicals, aided Zn2+, promoting oxygen deficiency Ce3+ concentration. synergistic efficacy ultimately translates composite PEMs characterized mere 4% mass loss nominal 6% decrease Km after rigorous exposure to Fenton's solution. Remarkably, improved power density 403.2 mW/cm2 maximum current 1260.6 mA/cm2 were achieved 2% (SPZ-2) at 75 °C 100% RH. performance SPZ-2 74% higher than its corresponding pristine membrane.

ABSTRACT Green Hydrogen (H 2 ) is generally considered to play a key role in enabling sustainable energy storage, as well renewable feedstock various industrial sectors. Accordingly, the production of H by water electrolysis at an scale prerequisite for transformation our system. With respect electrolysis, proton exchange membrane (PEM) electrolysers are technology option green on large scale. Prior market ramp‐up PEM have undergo substantial de‐risking ramp‐up. For comprehensive de‐risking, fundamental and holistic understanding degradation phenomena industrially relevant prerequisite. Field data with different application‐specific load profiles needs be acquired order develop countermeasures against possible patterns induced operational mode. This not only crucial more mature but also future other novel technologies such anion (AEM) looking make step from laboratory operation large‐scale deployment. editorial aims outline current status general workflow process serve introduction topics this special issue ranging studies processes catalyst level up factory concepts ramping electrolyser production.
