摘要：

Solid oxide fuel cells with an electrode supported thin film electrolyte are a promising alternative to electrolyte supported single cells because of decreased electrolyte resistance. The electrophoretic deposition (EPD) of the electrolyte was performed on A-site deficient La0.75Sr0.2MnO3-delta (ULSM) from three different suspensions: (Y2O3)(0.08)(ZrO2)(0.92) (YSZ), (Ce0.9Gd0.1)O-1.955 (GDC) and La0.9Sr0.1Ga0.8Mg0.2O2.85 (LSGM) in acetylacetone and isopropanol. The thickness of the deposits was controlled by varying the conditions of the electrophoretic deposition. Because of porosity reduction in the cathode layer during sintering of the electrolytes we deposited porous cathodes (La0.8Sr0.2MnO3-delta (LSM) and La0.6Sr0.4Fe0.8Co0.2O3-delta (LSCF)) as well as anodes (NiO/YSZ and NiO/GDC) on dense YSZ foils by applying a conductive layer on top of the surface part to be coated.
