چکیده انگلیسی
Powders of Gd0.8Sr0.2CoO3 (GSC) were prepared by a glycine–nitrate process. Symmetrical cathodes of GSC–50Ce0.9Gd0.1O1.95 (GDC) (50:50 by volume) powders were deposited on GDC electrolyte pellets, and the electrochemical properties of the interfaces between the porous cathode and the electrolyte were investigated at intermediate temperature (500–750 °C) using electrochemical impedance spectroscopy. The addition of 50 vol.% GDC to GSC resulted in an additional factor ≈3 decrease in the area-specific resistance (ASR). The ASR values for the GSC–50GDC cathodes were as low as 0.064 Ω cm2 at 700 °C and 0.16 Ω cm2 at 600 °C, respectively. The maximum power density of a cell using the GSC–50GDC cathode was 356 mW cm−2 at 700 °C.
