TLDR
In this article, a combined citrate-EDTA complexing method was used for the preparation of SCFO and Ba0.2O3-delta (BSCFO) oxides, and the results of O-2-TPD and XRD showed that the introduction of barium into SCFO could effectively suppress the oxidation of Co3+ and Fe3+ to higher valence states of Co4 and Fe4+ in the lattice and stabilize the perovskite structure under lower oxygen partial pressures.About:

A high-performance cathode for the next generation of solid-oxide fuel cells
Zongping Shao,Sossina M. Haile +1 more
TL;DR: BSCF is presented as a new cathode material for reduced-temperature SOFC operation and demonstrated that BSCF is ideally suited to ‘single-chamber’ fuel-cell operation, where anode and cathode reactions take place within the same physical chamber.

Oxygen permeation through perovskite-type oxides
TL;DR: In this article, mixed conductive perovskite-type oxides are shown to be promising materials for oxygen permeation at elevated temperatures, showing that the permeability was mainly controlled by the amount of oxygen vacancies.
Journal ArticleDOI
Electrochemical Properties of Mixed Conducting Perovskites La1 − x M x Co1 − y Fe y O 3 − δ (M = Sr, Ba, Ca)
TL;DR: In this article, the perovskite compositions exhibited high electronic and ionic conductivity and substantial reversible weight loss at elevated temperatures as the materials became increasingly oxygen deficient, which resulted in a decrease in the electronic conductivity.

Importance of the surface exchange kinetics as rate limiting step in oxygen permeation through mixed-conducting oxides
TL;DR: In this paper, the surface exchange kinetics in limiting the rate of oxygen permeation through mixed-conducting oxide ceramics are investigated. But the authors focus on the perovskite type oxides.

TL;DR: In this paper, perovskite type oxides (ABO3) containing transition metals on the B-site show mixed (electronic/ionic) conductivity, and extruded tubes of these materials have been evaluated in a reactor operating at ca. 850°C for direct conversion of methane into syngas (CO + H2) in the presence of a reforming catalyst.

Oxygen permeation studies of SrCo0.8Fe0.2O3 − δ
TL;DR: In this paper, the phase diagram of SrCo 0.80 Fe 0.20 O 3 − δ membranes was discussed in relation to the phase diagrams of the surface exchange process, and it was shown that surface exchange is the rate limiting step in the overall permeation mechanism.
