Summary: BaSrInFeO5 (BSIF) is a new cathode material designed for proton-conducting solid oxide fuel cells (SOFCs) by modifying the Ba2In2O5 proton conductor with Sr and Fe cations. Sr doping improves the chemical stability, formation of oxygen vacancies, and proton mobility of the material. Experimental studies and first-principles calculations demonstrate that an H-SOFC using the BSIF cathode achieves a high peak power density of 1192 mW cm-2 at 700 oC, surpassing previous reports. This study suggests that derived cathode materials from less-studied Ba2In2O5 could offer new material selections for H-SOFCs.

Summary: The study demonstrates that tailoring the electronic structure of perovskite oxide with Mo-doping leads to improvements in cathode materials for proton-conducting solid oxide fuel cells. The Mo-doping changes the electronic structure of the oxide, making the metal-oxygen bond less strong and the surface more active towards oxygen reduction, resulting in more feasible oxygen vacancy formation critical for protonation. The electric field induced by Mo-doping provides an additional driving force for proton movement, accelerating proton migration in the oxide and improving cathode performance.

Summary: LiCoO2, a material widely used in Li-ion batteries, was found to be suitable as a cathode material for H-SOFCs. The evaporation of Li in LiCoO2 led to the in-situ formation of a LiCoO2+Co3O4 composite, which greatly enhanced the performance of the cathode in H-SOFCs. The formation of Co3O4 due to Li-evaporation decreased the formation energy of oxygen vacancies, resulting in improved cathode performance.

Summary: Nonprecious-metal heterogeneous catalysts with atomically dispersed active sites have shown high activity and selectivity in various reactions, but their rational design and large-scale synthesis pose a significant challenge. Current approaches involve high temperatures and tedious procedures. In this study, a straightforward and scalable strategy was demonstrated for synthesizing atomically dispersed Ni electrocatalysts in a large quantity with high yield, using two simple steps under mild conditions. The resulting catalyst exhibits excellent catalytic performance in both oxygen evolution and reduction reactions, with tunable activity, high reproducibility, and stability. The strategy provides a practical and green method for the industrial manufacturing of nonprecious-metal single-site catalysts with predictable structures.
