Abstract The coupling of photovoltaics (PVs) and PEM water electrolyzers (PEMWE) is a promising method for generating hydrogen from renewable energy source. While direct feasible, the variability solar radiation presents challenges in efficient sizing. This study proposes an innovative management strategy that ensures stable production rate, even with fluctuating irradiation. By integrating battery-assisted production, this approach allows decentralized, grid-independent systems, mitigating instability PV intermittency. system utilizes electrochemical storage to absorb excess during periods low or very high irradiation, which falls outside electrolyzer’s optimal power input range. stored then supports system, ensuring electrolyzer operates near its nominal capacity optimizing lifetime. achieves efficiency 7.78 8.81% at current density region 6.6% converting into hydrogen.

Abstract Long‐term operation of proton exchange membrane water electrolysis (PEMWE) poses significant challenges due to the high potential and strong acidic environment associated with oxygen evolution reaction (OER), leading severe catalyst degradation. Here, ultrafine iridium–ruthenium nanowires (IrRu NWs) are developed through a facile process, which exhibits excellent activity stability for OER. The IrRu NWs achieve an overpotential 243 mV at 10 mA cm −2 , is significantly lower than that commercial IrO 2 pure Ir nanowires. Importantly, demonstrate 17.6% higher current density V in real PEMWE device Pt/C catalysts anode cathode, respectively. layers can be stably operated 1.0 1.5 A more 500 h degradation rate only 28 µV −1 makes promising toward applications.
