Impedance characterization of supported oxygen ion conducting electrolytes [PDF]
Solid State Ionics, 2019 Abstract Electrochemical impedance spectroscopy is a widely used tool to study electrochemical reactions in batteries, fuel cells and other electrochemical energy conversion devices. However, conduction processes in the electrolyte of high temperature fuel or electrolysis cells (SOFC/SOEC) are inaccessible during operation, severely restricting the ...

Proton and Oxygen-Ion Conductivities of Hexagonal Perovskite Ba5In2Al2ZrO13
Materials, 2022 The hexagonal perovskite Ba5In2Al2ZrO13 and In3+-doped phase Ba5In2.1Al2Zr0.9O12.95 were prepared by the solid-state synthesis method. The introduction of indium in the Zr-sublattice was accompanied by an increase in the unit cell parameters: a = 5.967 Å, c = 24.006 Å vs. a = 5.970 Å, c = 24.011 Å for doped phase (space group of P63/mmc).

Effect of ion implantation doping on electrical properties of yttria-stabilized zirconia thin films [PDF]
, 1992 The change in conductivity of Fe and Ti implanted rf-sputtered layers of yttria-stabilized zirconia (YSZ) was studied as a function of the temperature (400–800°C) and oxygen partial pressure. In an oxidized state and in the temperature range of 400–600°C,
