Incorporation of GDC nanoparticles into the chemical solution resulted in a relatively dense and uniform microstructure without major microstructural heterogeneities. A highly active LaSrCoO3 (LSCF) cathode layer was also deposited by multiple spin coating of LSCF chemical solution containing LSCF nanoparticles, and was sintered at 950 degrees C to maintain thermodynamic stability of the GDC interdiffusion barrier layer with the help of the GDC-LSCF cathode functional layer. A cell developed on a conventionally process half cell exhibited excellent power outs of 810, 470, and 240 mW/cm(2) at 650, 600, and 550 degrees C, respectively.
