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.

Abstract Proton ceramic fuel cells (PCFCs) are favored for their excellent performance under medium‐temperature conditions. However, advancement is limited by sluggish oxygen kinetics and the lack of highly compatible cathodes. Nanocatalysts produced via in situ exsolution have emerged as a promising solution to overcome limitations conventional PCFC cathode catalysts. A novel three‐phase composite cathode, synthesized ion topology engineering, achieves enhanced PCFCs. By introducing transition metal V into BaCe 0.25 Fe 0.75 O 3‐δ (BCF), BaFe 2 4 nanoparticles formed on surface through Fe‐Ba‐V exchange, simultaneously creating BaCeO 3 ‐BaFe 1‐x x co‐catalyzed interface. This exhibits superior adsorption‐dissociation capabilities serves an efficient proton conduction carrier. The self‐assembled , with its low thermal expansion coefficient, reduces material's overall improves cathode‐electrolyte compatibility. Additionally, cathode's stability catalytic activity significantly enhanced. PCFCs utilizing BCF‐V achieved impressive power density 1.73 W cm −2 at 650 °C maintained stable operation over 200 h 600 °C.
