Advancements in Solid Oxide Fuel Cells

A range of proton-conducting ceramic electrolytes with varying stoichiometries were investigated, including BaZr 0.7 Ce 0.2 Y 0.1 O 3 , BaZr 0.2 Ce 0.7 Y 0.1 O 3 , BaZr 0.4 Ce 0.4 Y 0.1 Yb 0.1 O 3 , and BaCe 0.5 Zr 0.35 Y 0.15 O 3 , each sourced from different suppliers. These materials were processed and sintered und…

This work reveals the structural evolution and transport behavior of chromium-substituted Ba2In2O5 (BIO) as a mixed ionic electronic conductor for oxygen transport membranes. Controlled substitution of In3+ by Cr6+ induces a transition from an orthorhombic brownmillerite to an on average cubic defect-perovskite (ABO3−…

ABSTRACT Grain boundaries (GBs) are unavoidable extended defects in polycrystalline materials that often lead to charge‐carrier blocking. Their presence, in turn, depresses device performance and/or accelerates degradation. Attempts to systematically identify the source or control these barriers remain scarce. Here, w…

ABSTRACT In this study, the electrochemical charge–discharge behavior of a binder‐free, self‐supporting, porous three‐dimensional (3D) LCNO‐derived multiphase La–Cu–Ni–O ceramic electrode (LCNO‐MP) fabricated from a nominal La 2 CuNiO 6 precursor powder (LCNO) was investigated. The sintered electrode derived from this…
