Abstract Perovskite oxides have emerged as alternative anode materials for hydrocarbon‐fueled solid oxide fuel cells (SOFCs). Nevertheless, the sluggish kinetics hydrocarbon conversion hinder their commercial applications. Herein, a novel dual‐exsolved self‐assembled CH 4 ‐fueled SOFCs is developed. The designed Ru@Ru‐Sr 2 Fe 1.5 Mo 0.5 O 6‐δ (SFM)/Ru‐Gd 0.1 Ce 0.9 2‐δ (GDC) exhibits unique hierarchical structure of nano‐heterointerfaces exsolved on submicron skeletons. As result, Ru@Ru‐SFM/Ru‐GDC anode‐based single cell achieves high peak power densities 1.03 and 0.63 W cm −2 at 800 °C under humidified H , surpassing most reported perovskite‐based anodes. Moreover, this demonstrates negligible degradation over 200 h in indicating resistance to carbon deposition. Density functional theory calculations reveal that created metal‐oxide heterointerfaces Ru@Ru‐SFM Ru@Ru‐GDC higher intrinsic activities compared pristine SFM. These findings highlight viable design efficient robust SOFCs.

Zinc-air batteries (ZABs) are highly promising for flexible electronics due to their high energy density and cost-effective. However, practical application is impeded by the sluggish kinetics of oxygen evolution reduction reactions (OER/ORR). This study presents a novel design featuring BaO nanoparticles anchored on layered perovskite PrBaMn1.5Co0.5O6-δ (PBMC) nanofibers, fabricated through plasma method. Notably, treatment induces selective exsolution A-site Ba onto surface, while simultaneously driving transformation PBMC from simple perovskite, resulting in unique BaO/PBMC heterostructure. Theoretical calculations demonstrate that construction heterojunction regulates interfacial electronic redistribution, thereby lowering barriers both OER ORR. Consequently, air electrode exhibits superior peak power enhanced stability solid-state ZABs, compared pristine cathode. Selective coupled with phase transition, alkaline-earth metal oxide/perovskite heterostructure, may offer new insights conversion technologies.
