The experimental results coupled density functional theory (DFT) calculations verify that at A‐site significantly induces NiO nanoparticles exsolved B‐site, promoting formation biphasic composite structure dramatically increases electrochemical active sites. Remarkably, R‐PCCs using N‐XFN achieve impressive peak 1.30 W cm −2 fuel cell mode current ‐2.52 A 1.3 V electrolysis 650 °C. In addition, show excellent stability reversibility over 830 h, including 500 h 330 reversible operation This research provides important insights into design perovskites, paving way advanced technology.

Abstract Solid oxide fuel cells (SOFCs) are considered as advanced energy conversion technologies due to the high efficiency, flexibility, and all‐solid structure. Nevertheless, their widespread applications strongly hindered by operational temperatures, limited material selection choices, inferior long‐term stability, relatively costs. Therefore, reducing temperatures of SOFCs intermediate‐temperature (IT, 500–800 °C) range can remarkably promote practical enabling use low‐cost materials enhancing cell stability. conventional cathodes for high‐temperature display electrocatalytic activity oxygen reduction reaction (ORR) at reduced temperatures. Barium cobaltite (BaCoO 3‐δ )‐based perovskite oxides regarded promising IT‐SOFCs because free lattice volume large vacancy content. However, BaCoO ‐based suffer from poor structural thermal compatibility, insufficient ionic conductivity.

Abstract Zinc–air batteries (ZABs) hold significant promise for flexible electronics due to their high energy density and low cost. However, practical application is hindered by the sluggish kinetics of oxygen evolution reduction reactions (OER/ORR). This study highlights a novel design vertical graphene arrays (VGs) anchored on PrBa 0.5 Sr Co 1.8 Ru 0.2 O 5+δ (PBSCRu) perovskite nanofibers, fabricated via plasma‐enhanced chemical vapor deposition. Notably, VG growth induces exsolution nanoparticles from PBSCRu perovskite, resulting in unique PBSCRu‐Co‐VG heterostructure. Theoretical calculations demonstrate that constructing heterojunction regulates interfacial electronic redistribution, thereby lowering barriers both OER ORR. As result, PBSCRu@VG‐5 electrocatalyst exhibits superior stability higher peak power liquid solid‐state ZABs compared pristine electrocatalyst. protocol advances integration synergetic perovskite/metal/graphene composites, offering considerable potential next‐generation conversion technologies.
