Abstract The development of high‐performance fuel electrodes exhibiting exceptional catalytic activity and flexibility remains a critical challenge for advancing solid oxide cells (SOCs). However, current Ni‐YSZ cermet or suffer from either poor limited electrochemical activity. This study presents novel strategy creating heterogeneous interfaces through the first‐reported exsolution mangosteen‐type FeRu nanoalloy clusters Sr 1.9 Fe 1.5 Mo 0.43 Ru 0.07 O 6‐δ (Ru‐SFM0.07‐1.9) electrodes. combination clusters, oxygen vacancies, significantly enhances by providing more sites reducing activation energy C─H bond cleavage. Concurrently, formation vacancies improves resistance to carbon deposition flexibility. SOC with Ru‐SFM0.07‐1.9 electrode achieves peak power densities (P max ) 1.79, 1.54, 1.36, 1.13 W cm −2 under H 2 , naphtha, propane, methane at 850 °C in cell (FC) mode, respectively. While it exhibits 3.29 A 1.6 V CO electrolysis (EC) mode. These results demonstrate that construction is promising enhance both SOCs.

Co-expression of multi-genes for polynary perovskite electrocatalysts for reversible solid oxide cells

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 25, 2025

High-entropy LnBaCo2O5+δ perovskites are explored as rSOC air electrodes, though high configuration entropy (Sconfig) alone poorly correlates with performance due to multifactorial interactions. We systematically engineer (Ln = lanthanides) tunable Sconfig and 20 consistent parameters, employing Bayesian-optimized symbolic regression decode activity descriptors. The model identifies synergistic contributions from Sconfig, ionic radius, electronegativity, enabling screening of 177,100 compositions. Three validated oxides exhibit superior activity/durability, particularly (Pr0.05La0.4Nd0.2Sm0.1Y0.25)BaCo2O5+δ, showing enhanced oxygen vacancy concentration disordered transport pathways. First-principles studies reveal optimized charge transfer kinetics via cobalt-oxygen bond modulation. Further, the interplay between first ionization energy, atomic mass, Lewis acidity dictates stability. This data-driven approach establishes a quantitative framework bridging engineering catalytic functionality in complex oxides. Polynary perovskite promising electrodes for rSOCs, often linked reactivity. However, does not strongly correlate performance. study develops identifying key descriptors guide high-activity oxide discovery.

Опубликована: Окт. 29, 2024

Abstract The co‐generation of electricity and chemicals via direct internal reforming solid oxide fuel cells (DIR‐SOFCs) offers a promising route to carbon‐neutral energy solutions. However, challenges such as inadequate performance fast degradation, particularly when using hydrocarbon fuels like CH 4 , hinder the deployment DIR‐SOFC technology. This study addresses three critical issues: effect composition on electrochemical properties, mechanisms microstructural impacts carbon deposition, practical feasibility DIR‐SOFCs at an industrial scale. First, comprehensive polarization impedance analyses are conducted assess impact varying compositions—specifically p (CH ) (H 2 O)—on performance. Second, advanced morphological characterization, machine learning‐assisted 3D reconstructions, numerical simulations utilized reveal deposition behavior its effects anode microstructures. Quantitative analysis carbon's pores, Ni, YSZ phases provides novel insights into carbon‐induced changes. Finally, industrial‐scale is validated, emphasizing both efficiency operational stability. enhances understanding mechanisms, offering crucial for optimizing design operation, laying groundwork their broader adoption in future.
