Synthèse par pulvérisation cathodique et caractérisation d'électrolytes solides en couches minces pour piles à combustible à oxydes solides (SOFC) fonctionnant à température intermédiaire :

Abstract : The major problem of Solid Oxide Fuel Cells (SOFC) is their operating temperature. One challenge is to decrease this temperature from 1000 to 700ÊC, this is the Intermediate Temperature SOFC technology. It's very important to decrease the thickness of the ionic conductor to reduce its resistance. In this context, the reactive magnetron sputtering is a powerful technique for elaborating the coating with a compatible thickness with the application (~ 5-10 m). After a description of the experimental device and of some specific analysis methods for this study, we present some results about the materials reference of the SOFC, the Yttria Stabilised Zirconia (YSZ). Then, we present some results about two new materials with higher ionic conductivity of oxygen than YSZ at 700ÊC: Gadolinia Doped Ceria (GDC) and Lanthanum Molydenum Oxide (LAMOX). At last, we present first results on the synthesis of the bilayer electrolyte coating: GDC/YSZ.
