Three different cathode configurations using porous layers of La0.4Ba0.6CoO3-delta (LBC), LBC-GDC composite in a 50:50 weight ratio, and GDC were prepared and measured by impedance spectroscopy on symmetrical cells. These three cathode configurations were: A) porous GDC + LBC, B) porous GDC + LBC GDC composite, and C) porous GDC + LBC-GDC composite + LBC. The minimum polarization resistance (Rp) value was obtained with configuration C. The incorporation of both the porous GDC layer and the intermediate layer of LBC-GDC composite, allowed us to solve adherence problems caused by the total expansion mismatch between LBC (26.10(-6) K-1) and GDC (12.10(-6) K-1). The Rp values obtained with cell C are comparable to the performance of another cell C prepared with Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF). For example, the Rp values at 600 degrees C, in air, were 0.071 and 0.065 Omega cm(2) for LBC and BSCF, respectively. These results suggest that configuration C is very promising for developing IT-SOFC cathode with low Rp values. Copyright (C) 2012, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
