Effect of YSZ fiber addition on microstructure and properties of porous YSZ ceramics
Journal of Materials Science, 2012Yttria-stabilized zirconia (YSZ) fiber was introduced as the reinforcement for porous YSZ ceramics fabricated by tert-butyl alcohol-based gel-casting process and pressureless sintering. Effect of YSZ fiber addition on the microstructure and properties of porous YSZ ceramics was studied systematically.

Microstructural evolution of YSZ electrolyte aerosol-deposited on porous NiO-YSZ
Journal of the European Ceramic Society, 2012Abstract Dense, crack-free, ∼7.5 μm thick, 8 mol% yttria stabilized zirconia (YSZ) film was aerosol deposited on porous NiO-YSZ anode substrates at room temperature without additional high-temperature sintering. The films’ microstructures and gas permeability were observed after annealing at various temperatures.

YSZ‐Induced Crystallographic Reorientation of Ni Particles in Ni–YSZ Cermets
Journal of the American Ceramic Society, 2007Metal–ceramic interfaces in Ni–YSZ (YSZ, yttria‐stabilized zirconia)‐textured porous cermets prepared by reduction of NiO–YSZ directionally solidified eutectics have been studied by transmission electron microscopy and X‐ray pole figure experiments. Before reduction of NiO, the interfacial plane is

Stabilization of Ni-YSZ Nanocomposite Anodes by Deposition of a Thin YSZ Overlayer
ECS Transactions, 2015Lowering the operating temperatures of solid oxide fuel cells (SOFCs) to below 600 °C is projected to enhance the long term stability of these devices by slowing down thermally induced microstructural changes in the electrodes. To minimize the electrode resistance caused by the lowered operating temperatures, the fabrication of nanocomposite Ni-YSZ ...

ac polarization phenomena of the YSZ/Rh and YSZ/Pd electrode systems
Solid State Ionics, 1989Abstract Electrode characteristics of YSZ/Rh and YSZ/Pd were studied as a function of oxygen partial pressure and temperature by ac impedance spectroscopy. Similar impedance spectra were observed in both systems. Below the decomposition pressure of Rh 2 O 3 and PdO the impedance spectrum consisted of two arcs. Both arcs, especially the low frequency

Three-Dimensional EBSD Analysis of YSZ, NiO-YSZ and Ni-Alloy
MRS Proceedings, 2012ABSTRACTIn this report, a method is discussed to perform successive milling on yttria-stabilized zirconia (YSZ), NiO-YSZ and Ni-alloy at the intervals of 85 nm 50 nm and 100 nm, respectively using a focused ion beam (FIB) followed by electron backscatter diffraction (EBSD) analysis on each slice.

Promoting effect of YSZ on the electrochemical performance of YSZ+LSM composite electrodes
Solid State Ionics, 1998In the present study, the YSZ + La0.8Sr0.2MnO3 composite electrodes with addition of varying amounts of YSZ have been prepared on YSZ plates by a screen printing method. The electrodes were then examined by SEM and studied by AC impedance, cyclic voltammetry, potential step as well as polarization technique.
