Abstract

This paper describes the effects of (La0.60Sr0.40)0.95Co0.20Fe0.80O3-x (LSCF) firing temperature on the electrochemical performance and the chemical interactions at the interface of Gd-doped ceria (GDC) barrier layer and yttria-stabilized zirconia (YSZ) electrolyte for commercial cells. Initial scanning electron microscopy (SEM) analysis indicate that the optimal cathode porosity is obtained at a firing temperature of 1100
