Preparation of NiO-YSZ Substrate for Electrophoretic Deposition of Thin YSZ Film

Preparation of NiO-YSZ/YSZ bi-layers for solid oxide fuel cells by electrophoretic deposition

A simple and cost-effective method, starting with electrophoretic deposition (EPD) on a carbon sheet, has been developed for preparation of a iO-YSZ anode and thin, gas-tight YSZ electrolyte layer on it for use in solid oxide fuel cells (SOFCs). The innovative feature of this approach nables the deposition of anode materials as well as the YSZ electrolyte, which were subsequently co-fired in ai...

Optimization of DC reactive magnetron sputtering deposition process for efficient YSZ electrolyte thin film SOFC

Yttria-stabilized zirconia (YSZ, ZrO2:Y2O3) thin films were deposited by reactive DC magnetron sputtering with a high deposition rate from a metallic target of Zr/Y in an argon/oxygen atmosphere. Plasma parameters and composition analysis of the gas phase reveal that the sputtering process in the “compound” mode is reached for a 2.5 sccm oxygen flow rate. Deposition onto silicon in “metal” mode...

Compositionally graded YSZ-NiO composites by surface laser melting

Laser surface melting has been applied to near eutectic NiO-YSZ sintered ceramics. The objective is to generate a functional gradient composite material with graded microstructure and composition. At low solidification rates the resultant material has a graded composition, with a severe NiO segregation towards the surface. A thick NiO layer whose thickness depends on the travelling speed is for...

Oxygen-ion Transfer between YSZ/YSZ and YSZ/LSCF under Mechanical Contact Stress

The present study concerns oxygen-ion transfer between yttriastabilized zirconia single crystals (YSZ/YSZ) under mechanical contact stress. Two YSZ single crystal plates were piled up between platinum meshes, and contact stress was mechanically applied. The interfacial conductivity as well as the bulk conductivity was successfully measured with this setup. The interfacial conductivity is greatl...
