Developing high-performance, highly durable, low-cost electrolysis systems is essential for sustainable hydrogen production with reduced installation and operational costs. Practical accelerated stress test protocols are crucial to assess the performance durability of electrolyzers, which need a lifespan of over a decade. Additionally, investigating performance durability under diverse operating conditions is necessary. This research employs an accelerated stress test protocol, compressing 24 h of solar power generation into a minute and operating continuously for five days. The impact of anode structure on performance durability is analyzed using the accelerated stress test protocol, revealing performance degradation under the rainy-day protocol. Finally, better dispersibility led to lower current density reduction (0.38 A/cm2) in rainy-day protocol, compared to poorly dispersed water-based electrode's reduction (0.57 A/cm2), indicating improved durability.
