Abstract

Gadolinium Doped Ceria (GDC) diffusion barrier layer was formed on the Yttrium Stabilized Zirconia (YSZ) electrolyte to apply La_0.6Sr_0.4Co_0.2Fe_0.8O₃ (LSCF) cathode system for lowering the operating temperature of solid oxide fuel cell. In this study, YSZ and GDC layers were coated by dip coating method which possibly coat one-side of anode substrate. Cu(NO₃)₂ was infiltrated into pre-sintered substrate of anode and electrolyte as a sintering aid for lowering the co-firing temperature which was enough to produce dense electrolyte layer. LSCF-GDC cathode was coated on the GDC layer by screen printing method. The cells were operated at 600°C and 650°C. The microstructures of the surface and cross-section were observed by scanning electron microscopy (SEM). The ohmic and polarization resistance were measured by the electrochemical impedance spectroscopy (EIS). The cell performance was measured by I-V curve observation.
