Abstract Direct‐ammonia proton ceramic fuel cell (DA‐PCFC) is a promising clean energy technology because ammonia (NH 3 ) easier to store, transport, and handle than hydrogen. However, NH decomposition efficiency unsatisfactory, the anti‐sintering resistance of conventional Ni‐based anodes has limited large‐scale application DA‐PCFC technology. Herein, Pr 0.6 Sr 0.4 (Co 0.2 Fe 0.8 0.85 Ru 0.15 O 3‐δ (PSCFR15), novel anode catalyst layer (ACL) material developed. PSCFR15 treated under...
Abstract The Nb‐doped lanthanum strontium ferrite perovskite oxide La 0.8 Sr 0.2 Fe 0.9 Nb 0.1 O 3− δ (LSFNb) is evaluated as an anode material in a solid fuel cell (SOFC). effects of partial substitution the crystal structure, electrical conductivity, and valence ions are studied. LSFNb exhibits good structural stability severe reducing atmosphere at 800 °C, suggesting that high‐valent can effectively promote lattice structure. concentration 2+ increases after doping, confirmed by X‐ray...
Abstract Nano‐single‐atom‐catalysts have the potential to combine respective advantages of both nano‐catalysts and single‐atom‐catalysts thus exhibit enhanced performance. Generally, separation active sites in space limits interaction between single atoms nanoparticles. Heterointerface engineering has break this limitation. Regretfully, studies on interface effect nanoparticles are rarely reported. Herein, an unprecedented nano‐single‐atom heterointerface composed Fe single‐atoms...
Abstract Solid oxide cells (SOCs) hold considerable promise as devices for efficient, reversible conversion between chemical and electrical energy, facilitating a global shift toward renewable energy. Electrode performance is critical SOC efficiency durability composite materials are key to developing high‐performance electrode catalysts. However, conventional mechanical mixing infiltration methods often lead large particle sizes, uneven distribution, weak interfacial interactions, thus...

Abstract Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) is a conventional anode material for solid oxide electrolysis cells (SOECs) to catalyze oxygen evolution reaction (OER). However, the inferior chemical stability of BSCF results in severe surface segregation and performance degradation under high temperatures. A critical challenge lies alleviating preserving OER anode. Herein, lanthanides are introduced substitute Ba BSCF, labeled as Ln0.5Sr0.5Co0.8Fe0.2O3-δ (LnSCF, Ln=La, Pr, Nd, Sm), regulate its...
The low performance and insufficient catalytic activity of perovskite anodes hinder their further application in intermediate-temperature solid-oxide fuel cells (IT-SOFCs). A novel La0.8 Sr0.2 Fe0.9 Nb0.1 Pd0.04 O3-δ (LSFNP) anode material has been developed with Fe-Pd co-exsolutions for IT-SOFCs. Fe0 Pd0 metallic nanoparticles are confirmed to exsolve on the surface during operation under a hydrogen atmosphere. introduced Pd exsolutions promote charge-transfer process slightly H2...
