Hydrogen energy, derived from the electrolysis of water using renewable energy sources such as solar, wind, and hydroelectric power, is considered a promising form of energy to address the energy crisis. However, the anodic oxygen evolution reaction (OER) poses limitations due to sluggish kinetics. Apart from high catalytic activity, the long-term stability of electrocatalytic OER has garnered significant attention. To date, several research studies have been conducted to explore stable electrocatalysts for the OER. A comprehensive review is urgently warranted to provide a concise overview of the recent advancements in the electrocatalytic OER stability, encompassing both electrocatalyst and device developments. This review aims to succinctly summarize the primary factors influencing OER stability, including morphological/phase change and electrocatalyst dissolution, as well as mechanical detachment, alongside chemical, mechanical, and operational degradation observed in devices. Furthermore, an overview of contemporary approaches to enhance stability is provided, encompassing electrocatalyst design (structural regulation, protective layer coating, and stable substrate anchoring) and device optimization (bipolar plates, gas diffusion layers, and membranes). Hopefully, more attention will be paid to ensuring the stable operation of electrocatalytic OER and the future large-scale water electrolysis applications. This review presents design principles aimed at addressing challenges related to the stability of electrocatalytic OER.

电催化 OER 的稳定性：从原理到应用

氢能是使用太阳能、风能和水力发电等可再生能源电解水而获得的，被认为是解决能源危机的一种很有前途的能源形式。然而，由于动力学缓慢，阳极析氧反应（OER）带来了局限性。除了高催化活性外，电催化 OER 的长期稳定性也引起了广泛关注。迄今为止，已经进行了多项研究来探索用于 OER 的稳定电催化剂。迫切需要对电催化 OER 稳定性的最新进展进行简要概述，包括电催化剂和器件开发。本文旨在简明扼要地总结影响 OER 稳定性的主要因素，包括形态/相变和电催化剂溶解，以及机械分离，以及在设备中观察到的化学、机械和操作降解。此外，还概述了提高稳定性的现代方法，包括电催化剂设计（结构调节、保护层涂层和稳定的基材锚定）和器件优化（双极板、气体扩散层和膜）。希望人们能够更加关注确保电催化 OER 的稳定运行和未来的大规模水电解应用。本文提出了旨在解决与电催化 OER 稳定性相关的挑战的设计原则。
