Journal ArticleDOI
Applicability of emf measurements under external load resistance conditions for ion transport number determination
TL;DR: In this article, the applicability of concentration cells for the ion transference number measurements with external load was simulated with variable transport properties of the cell material, external load resistance, geometrical factors such as ion-conducting membrane thickness, and electrode kinetics.
Journal ArticleDOI
Mixed conductivity of garnet phases based on gadolinium ferrite
TL;DR: In this paper, the incorporation of Pr and Ca into the garnet lattice of Gd3Fe5O12±δ was found to increase the electronic conductivity, and to decrease the thermal expansion coefficients and oxygen ion transference numbers.
Journal ArticleDOI
Electrical, electrochemical, and thermomechanical properties of perovskite-type (La 1−x Sr x ) 1−y Mn 0.5 Ti 0.5 O 3−δ ( x = 0.15–0.75, y = 0–0.05)

TL;DR: In this paper, the tracer diffusion coefficients measured by the 18O/16O isotopic exchange depth profile method with time-of-flight secondary-ion mass spectrometric analysis are lower compared to lanthanum-strontium manganites.
Journal ArticleDOI
Oxygen separation using Bi2O3-based solid electrolytes
TL;DR: In this paper, the use of solid electrolytes of ternary system Bi 2O3-ZrO2-Y2O3, having high ionic conductivity, offers reduction in the polarization resistance of electrochemical cells with silver electrodes, as compared with electrolytes Bi(Y)O1.5.
Journal ArticleDOI
