Oxygen Permeability of Ce0.8Gd0.2 O 2 − δ ‐ La0.7Sr0.3MnO3 − δ Composite Membranes
Vladislav V. Kharton,Andrei V. Kovalevsky,A. P. Viskup,Filipe M.L. Figueiredo,Aleksey A. Yaremchenko,E.N. Naumovich,Fernando M.B. Marques +6 more
TL;DR: In this article, the authors showed that the oxygen transfer is limited by the bulk ionic conductivity of CGO and LSM composite ceramics, caused by diffusion of lanthanum and strontium into CGO.
Journal ArticleDOI
Thermal and chemical induced expansion of La0.3Sr0.7(Fe,Ga)O3−δ ceramics
Vladislav V. Kharton,Vladislav V. Kharton,Aleksey A. Yaremchenko,Mikhail V. Patrakeev,E.N. Naumovich,Fernando M.B. Marques +5 more
TL;DR: The linear thermal expansion coefficients (TECs) of perovskite-type La 0.3 Sr 0.7 Fe(Ga)O 3− δ ceramics are determined by dilatometric and high-temperature X-ray diffraction techniques, and the TEC values are in the range (19 −41)×10 −6 K −1 at 770 −1170 K, decreasing when the oxygen partial pressure or gallium concentration increases.
Journal ArticleDOI
Chemically Induced Expansion of La2NiO4+δ-Based Materials
Vladislav V. Kharton,Andrei V. Kovalevsky,Maxim Avdeev,Ekaterina V. Tsipis,Mikhail V. Patrakeev,Aleksey A. Yaremchenko,Eugene N. Naumovich,Jorge R. Frade +7 more
TL;DR: In this paper, the equilibrium chemical strains induced by the oxygen hyperstoichiometry variations in mixed-conducting La2Ni1-xMxO4+δ (M = Fe, Co, Cu; x = 0−0.2) with K2NiF4-type structure, were studied by controlled-atmosphere dilatometry at 923−1223 K in the oxygen partial pressure range 5 × 10-4 to 0.7 atm.
Journal ArticleDOI
Research on the electrochemistry of oxygen ion conductors in the former Soviet Union
TL;DR: In this paper, the authors focused on the analysis of experimental results on oxygen ion-conducting ceramic materials based on HfO2, CeO2 and ThO2 in the former Soviet Union.
Journal ArticleDOI
Electrode materials and reaction mechanisms in solid oxide fuel cells: a brief review. III. Recent trends and selected methodological aspects
TL;DR: In this paper, a short overview of novel cathode and anode materials, their electrochemical performance in contact with oxygen anion- and proton-conducting solid electrolytes, and specific features determining possible applications are presented.
