Abstract:
Ceramics solid oxide fuel cells (µSOFC) and potentiometric oxygen sensor with low and intermediary operating temperatures will be developed in thin films technology by Pulsed Laser Deposition (PLD) on Si (100) using the importance of 20% SDC [1,2,3,4]. 20%Ni-SDC [5] is deposed on SDC at 100.000 pulses compared with 27.000 for SDC. The microstructure of this bilayer is characterized by XRD, SEM, AFM, XPS; optical characterization is made by variable spectroelipsometry. The temperatures of substrates are fixed at 500C and 600C. Crystalline cubic structure with good uniformity will assure further developments in these fields.
