Yttriadoped zirconia as solid electrolyte for fuelcell applications: Fundamental aspects,Used
Delivery time: 8-12 business days (International)
Yttriadoped zirconia (YDZ) has been used as electrolyte for solid oxide fuel cells (SOFCs) for many years. Nevertheless, fundamental questions regarding the thermal stability and thus the degradation of ionic conductivity of YDZ are controversially discussed in literature. In this study, thickfilm and solgel prepared thinfilm YDZ electrolytes with yttria concentrations in the range of 7.310 mol% were investigated by transmission electron microscopy (TEM) with emphasis on microstructural and chemical changes during hightemperature operation. In general, nanoscaled regions of metastable tetragonal YDZ were found in all investigated specimens. Depending on dopant concentration and thermal treatment, the microstructural and chemical decomposition of the material on the scale of 10 nm could be shown by quantitative analytical TEM. Hence, clarifying conclusions regarding the YDZ phase diagram in the targeted dopant range are drawn. A revised boundary of the instability region, in which YDZ has to be expected to decompose, is presented. In conclusion, the developing inhomogeneities in decomposing YDZ are discussed as reason for the decrease of ionic conductivity during operation.
