Characterization 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...
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...
متن کاملSOFC Anodes Based on Infiltration of La0.3Sr0.7TiO3
Composites formed by infiltration of 45 wt % La0.3Sr0.7TiO3 (LST) into 65% porous yttria-stabilized zirconia (YSZ) were examined for application as solid oxide fuel cell (SOFC) anodes. Although LST does not react with YSZ, the structure of the LST deposits was strongly affected by the calcination temperature. At 1373 K, the LST formed loosely packed, 0.1 μm particles that filled the YSZ pores. ...
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...
