Resumen:
The Yttria stabilized Zirconia (YSZ) is a standard
electrolyte for solid oxide fuel cells (SOFCs), which are potential candidates for next generation portable
and mobile power sources. YSZ electrolyte thin films having a cubic single
phase allow reducing the SOFC operating temperature without diminishing the
electrochemical power density. Films of 8 mol % Yttria stabilized Zirconia
(8YSZ)and films with addition of 4 weight % Ceria (8YSZ + 4CeO2)(PLD) technique
using 8YSZ and 8YSZ + 4CeO2deposited on Soda-Calcia-Silica glass and Si(100)
substrates at room temperature. The morphology and structural characteristics
of the samples have been studied by means of X-ray diffraction and scanning electron
microscopy. Films of a cubic-YSZ single phase with thickness in the range of
1-3 µm were grown on different substrates.
