The drive towards increased energy efficiency and reduced air pollution has led to
accelerated worldwide development of fuel cells. As the performance and cost of fuel cells …

La BO 3 (B= Mn, Fe, Co, and Ni) perovskites form a family of materials of significant interest
for cathodes of solid oxide fuel cells (SOFCs). In this paper ab initio methods are used to …

La0. 6Sr0. 4CoO3− δ (LSC) thin film cathodes synthesized by pulsed laser deposition at
450° C (LSC_450° C) and 650° C (LSC_650° C) exhibit different electrochemical …

Finding new collective electronic states in materials is one of the fundamental goals of
condensed matter physics. Atomic-scale superlattices formed from transition metal oxides …

Following previous surveys of the solid electrolyte ceramics and electrode reaction
mechanisms in solid oxide fuel cells, this review is focused on the comparative analysis of …

It was shown through a comprehensive impedance spectroscopy study that the impedance
of the classic composite LSM: YSZ (lanthanum strontium manganite and yttria stabilized …

Optimization of electrical, optical, mechanical, and other properties of many advanced,
functional materials today relies on precise control of point defects. This article illustrates the …

LnBaCo2O5+ δ (Ln= La, Pr, Nd, Sm, Gd, and Y) was synthesized via an EDTA–citrate
complexing process. The particular Ln3+ dopant had a significant effect on the oxide's …

While SOFC perovskite oxide cathodes have been the subject of numerous studies, the
critical factors governing their kinetic behavior have remained poorly understood. This has …

As part of an investigation of new cathode materials for intermediate temperature solid oxide
fuel cells, we have investigated particular perovskite oxides with ordered A cations which, in …
