Electrochemical Performances of SOFC as Function of the Sputtered Parameters of the YSZ Electrolyte

Abstract

Yttria Stabilized Zirconia (YSZ) coatings were synthesized by reactive magnetron sputtering under different bias powers applied to the substrate holder and different thickness. All as-deposited coating presents a face centered cubic (f.c.c) structure of zirconia with dense and adhesive morphology. All coatings are adherent and the density increase with the bias power applied on the porte substrate holder. The best performance of the cell obtain in this study is 1060 mW.cm -2 at 650°C when the electrolyte thickness is 1.8 µm.
