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...
متن کاملAn Examination of SOFC Anode Functional Layers Based on Ceria in YSZ
The properties of solid oxide fuel cell (SOFC) anode functional layers prepared by impregnation of ceria and catalytic metals into porous yttria-stabilized zirconia (YSZ) have been examined for operation at 973 K. By varying the thickness of the functional layer, the conductivity of the ceria-YSZ composite was determined to be only 0.015–0.02 S/cm. The initial performance of anodes made with ce...
متن کاملInfluence of Treatment Temperature on Microstructure and Properties of YSZ–NiO Anode Materials
The cyclic treatment technique (redox cycling) comprising stages of material exposition in reducing and oxidizing high-temperature environments and intermediate degassing between these stages has been developed to improve the structural integrity of YSZ-NiO ceramic anode substrates for solid oxide fuel cells. A series of specimens were singly reduced in a hydrogenous environment (the Ar-5 vol% ...
متن کاملPreconditioning of the YSZ-NiO Fuel Cell Anode in Hydrogenous Atmospheres Containing Water Vapor
The YSZ-NiO ceramics for solid oxide fuel cells (SOFCs) anode have been investigated. A series of specimens were singly reduced in a hydrogenous atmosphere (Ar-5 vol% H2 mixture) at 600 °C under the pressure of 0.15 MPa or subjected to 'reduction in the mixture-oxidation in air' (redox) cycling at 600 °C. The YSZ-Ni cermets formed in both treatment conditions were then aged in 'water vapor in A...
متن کاملOptimization 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...
