Several processing Received in revised form parameters were systematically investigated to optimize cell microstructure and perfor- 2 February 2011 mance, including the amount of pore former used in the support substrate and the number Accepted 3 February 2011 of electrolyte coatings. Single cells with w240 mm thick NiO-YSZ support and 10 mm thick Available online 9 March 2011 YSZ electrolyte were successfully fabricated, demonstrating peak power densities of 752 and 277 mW cm2 at 800 and 600 C, respectively, when a composite cathode consisting of Keywords: La0.85Sr0.15MnO3 and Sm0.2Ce0.8O2d was used.
