Abstract Reversible protonic ceramic cells (R‐PCCs) are at the forefront of electrochemical conversion devices, capable reversibly and efficiently converting chemical energy into electricity intermediate temperatures (350–700 °C) with zero carbon emissions. However, slow surface catalytic reactions air‐electrode often hinder their performance durability. The electrode is not merely an extension bulk structure, equilibrium reconstruction can lead to significantly different crystal‐plane terminations morphologies, which influenced by material's intrinsic properties external reaction conditions. Understanding evolution elevated in water‐containing, oxidative atmospheres presents significant importance. In this review, a comprehensive summary recent processes applying advanced characterization techniques for high‐temperature surfaces provided, exploring correlations between fluctuations examining structural various associated degradation activation phenomena, offering insights impact on performance. Furthermore, reported strategies advances enhancing R‐PCCs through engineering discussed. This review offers valuable expected guide future developments catalysis, solid‐state ionics, materials.
