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 کاملCharacterization of YSZ-YST Composites for SOFC Anodes
Porous composites of Sr0.88Y0.08TiO3-δ (YST) and yttria-stabilized zirconia (YSZ) were formed by tapecasting methods and examined as potential anodes for SOFC. Even after calcination to 1773 K, the YSZ and YST crystallites remain as separate phases, as demonstrated by XRD and SEM with EDX analysis. Furthermore, it was possible to fabricate anode-supported electrolytes by calcination of a bilaye...
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 کاملFabrication and Characterizations of YSZ Electrolyte Films for SOFC
Yttria stabilized zirconia (YSZ) has been widely used as electrolyte in solid oxide fuel cell (SOFC). The effect of fabrication process on the properties of YSZ electrolyte thick film is discussed in the paper. With YSZ nano-powders of about 20-60nm as raw material, YSZ green adobe was fabricated by tape calendering process. Three-step sintering process was performed firstly holding at 1000°C f...
