abstract = {The thin Ce- and sintering aids-free BaZr0.8Y0.2O3-δ (BZY)
electrolyte layer was developed by the wet powder spraying
deposition. For this purpose, nanopowder was initially
prepared by the Pechini synthesis and consecutive milling to
d50 ~ 100 nm and further processed to environmentally
friendly aqueous dispersion. This dispersion was then coated
onto the pre-fired Ba(Zr,Ce,Y)O3-δ/NiO substrate by wet
powder spraying. By adjusting the process parameters, the
thickness of the final sintered electrolyte could be
controlled, with a minimum thickness as low as 1 μm. Dense
electrolyte layers were achieved by tuning the sintering
program. The thermal treatment procedure used for the
preparation of the substrate layer has been found to play a
crucial role in the sintering and densification of the
electrolyte. Acknowledgement: Chinese Scholarship Council
