LSM-YSZ nano-composite cathode with YSZ interlayer for solid oxide fuel cells

Journal of Energy Chemistry, 2017
Low temperature prepared (La-0.8 Sr-0.2)(0.9) MnO3-delta-Y-0.15 Zr-0.85 O-1.93 (LSM-YSZ) nano-composite cathode has high three-phase boundary (TPB) density and shows higher oxygen reduction reaction (ORR) activity than traditional LSM-YSZ cathode at ...

Effects of Polarization on the Microstructural Changes at the YSZ/Ni-YSZ Interface

ECS Transactions, 2019
This study examines the effect of Ni migration near the interface with the electrolyte after fuel cell (SOFC) and electrolysis mode (SOEC) operation on nickel-yttria stabilized zirconia (Ni-YSZ) electrodes. The experimental dataset consists in a series of short-stacks tested under different polarization conditions and durations.

New insights on the role of YSZ in a NiAl2O4/Al2O3–YSZ catalyst

Applied Catalysis A: General, 2015
Abstract Yttria stabilized zirconia (YSZ) role as co-support in alumina (Al2O3) supported Al–Ni spinel (NiAl2O4) was investigated from three perspectives: (a) influence on catalyst morphology, (b) influence on catalyst crystalline phases, and (c) role during diesel steam reforming tests.

Fabrication and Characteristics of YSZ–YSZ/Al2O3 Double-Layer TBC

Oxidation of Metals, 2011
A novel YSZ–YSZ/Al2O3 (YSZ means 6 wt% yttria partially stabilized zirconia) double-layer thermal barrier coating was fabricated using composite sol–gel and pressure filtration microwave sintering (PFMS) technologies. In this double-layer coating, the top layer was YSZ ceramics with a thickness of about 150 μm and the bottom layer was composed of micro-

Thermophysical Properties of YSZ and Ni-YSZ as a Function of Temperature and Porosity

2008
The thermal diffusivity, heat capacity, thermal conductivity, coefficient of thermal expansion adn elastic properties of Ni-YSZ and YSZ are reported in the temperature interval between 20C and 1000C. Specific heat capacity (Cp)and thermal diffusivity (a) were determined by differential scanning calorimetry (DSC) and by the laser flash method ...

Degradation of SPS-Fabricated YSZ and Nd2O3-YSZ Ceramics in Supercritical Water

Journal of Materials Engineering and Performance, 2016
Zirconia (ZrO2) ceramics are being considered as a candidate material for thermal insulating barriers in pressure tubes used in the supercritical water (SCW) nuclear reactors. However, the literature suggests that zirconia may undergo a detrimental phase transformation which is accelerated in aqueous environments.

Agglomeration behavior of nickel particles on YSZ and TiO2-doped YSZ electrolytes

Journal of Power Sources, 2012
Abstract Agglomeration behavior of nickel thin films on the yttria stabilized zirconia (YSZ) and TiO 2 doped-YSZ electrolytes under a reducing condition and at solid oxide fuel cell (SOFC) operating temperatures was investigated by scanning electron microscopy (SEM) and scanning probe microscopy (SPM) to clarify whether this method is appropriate to
