%X 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.
