EXPLORATION ELECTROPHORETIC DEPOSITION OF YSZ ELECTROLYTE FOR SOLID OXIDE FUEL CELLS

摘要

The suspensions of yttria stabilized zirconia (YSZ) were prepared in pure acetylacetone and ethanol and their mixtures. In all of the suspensions, YSZ thin films were obtained using electrophoretic deposition technique on the substrates of stainless steel and porous strontium-doped lanthanum manganite (LSM) which is a typical cathode materials used in solid oxide fuel cells (SOFCs). The deposition behavior in the different suspensions was studied. The deposited films were dried at room temperature and then sintered at high temperature. Observation with scanning electron microscopy (SEM) showed the sintered YSZ were of high density.
