Fabrication 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...
متن کاملPreparation 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 کاملPreparation of SOFC Anodes by Electrodeposition
Anodes for solid oxide fuel cells (SOFCs) have been prepared by electrodeposition of either Co or Ni into a layer of porous yttria-stabilized zirconia (YSZ), 60 μm thick. The YSZ, having 65% porosity, was prepared by tape casting with graphite pore formers and was attached to the dense YSZ electrolyte. After adding 10 vol % CeO2 by impregnation of aqueous solutions of CeNO3)3, followed by calci...
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 کاملSOFC Anodes Based on LST–YSZ Composites and on Y0.04Ce0.48ZrM0.48O2
The properties of solid oxide fuel cell (SOFC) anode functional layers prepared by impregnation of 1 wt % Pd and 10 wt % ceria into porous scaffolds of either Y0.04Ce0.48Zr0.48O2 (CZY) or composites of La0.3Sr0.7TiO3 (LST) and yttria-stabilized zirconia (YSZ) were examined to determine whether these scaffold materials would have sufficient electronic and ionic conductivity. Laminated tapes were...
