Journal ArticleDOI
Surface-limited oxygen transport and electrode properties of La2Ni0.8Cu0.2O4+δ
Vladislav V. Kharton,Vladislav V. Kharton,Ekaterina V. Tsipis,A.A. Yaremchenko,Jorge R. Frade +4 more
TL;DR: The submicron powder of La2Ni0.8Cu0.2O4+δ with K2NiF4-type structure, having grain size of 30-60 nm, was synthesized via glycine-nitrate process (GNP) and used for the preparation of porous cathode layers applied onto (La0.9Sr0.1)0.98Ga 0.8Mg0.
Journal ArticleDOI
The effect of cobalt oxide sintering aid on electronic transport in Ce0.80Gd0.20O2−δ electrolyte
Duncan P. Fagg,João C.C. Abrantes,Domingo Pérez-Coll,Pedro Núñez,Vladislav V. Kharton,Jorge R. Frade +5 more
TL;DR: The effect of cobalt oxide on the total electrical conductivity in air is negligible if the sintering is performed at 1173 K, although p-type electronic conduction measured at 900-1200 K increases with doping by 10-30 times as discussed by the authors.
Journal ArticleDOI
The stability and mixed conductivity in La and Fe doped SrTiO3 in the search for potential SOFC anode materials
Duncan P. Fagg,Vladislav V. Kharton,Andrei V. Kovalevsky,A. P. Viskup,E.N. Naumovich,Jorge R. Frade +5 more
TL;DR: In contrast to La free compositions, La containing compositions show high stability against reaction with yttria stabilised zirconia (YSZ) and a closely matching thermal expansion coefficient (∼1×10−5 K−1) as discussed by the authors.
Journal ArticleDOI
Oxygen Nonstoichiometry, Conductivity, and Seebeck Coefficient of La0.3Sr0.7Fe1−xGaxO2.65+δ Perovskites
Mikhail V. Patrakeev,E. B. Mitberg,A. A. Lakhtin,I. A. Leonidov,V.L. Kozhevnikov,Vladislav V. Kharton,Maxim Avdeev,Fernando M.B. Marques +7 more
TL;DR: In this paper, the role of gallium cations in the lattice is not passive, as it could be expected from the constant oxidation state of Ga3+ and the nonstoichiometry dependencies of the partial molar enthalpy and entropy of oxygen in La0.3Sr0.7(Fe,Ga)O2.65+δ, which increases with temperature, suggest a small-polaron conduction mechanism.
Journal ArticleDOI
Mixed conductivity and electrochemical behavior of (La0.75Sr0.25)0.95Cr0.5Mn0.5O3 − δ
Vladislav V. Kharton,Vladislav V. Kharton,Ekaterina V. Tsipis,I.P. Marozau,A.P. Viskup,Jorge R. Frade,John T. S. Irvine +6 more
TL;DR: In this paper, the electronic and oxygen-ionic transport in (La 0.75 Sr 0.25 ) 0.95 Cr 0.5 O 3 −−− δ solid electrolyte was studied at 1023 −1273 K in the oxygen partial pressure range from 10 −−20 to 0.5 ǫ atm.
