N2 - Solid oxide fuel cells (SOFCs) are recognized as environmentally friendly, highly efficient devices, and alternatives to conventional energy conversion systems. Typical material design used is the YSZ-based cell consisting of NiO-YSZ and LSM as anode and cathode, with a dense electrolyte of YSZ. When considering the use of hydrocarbon fuels, carbon deposition has been observed as major failure issue in electrodes. Also the homogeneity of the electrolyte is essential for the gas-tightness after sintering process. In this article, we propose an innovative chemical reactor with powder collection system and its application to glycine-nitrate combustion process to produce precision ceramic powder in nano scale; it not only generates precision ceramic powder of specific chemical composition on a mass-production scale, but also the system has the primary features of withstanding the instant hightemperature flare and pressure during powder formation reaction. Electrodes/electrolyte powders, SmBa0.5Sr0.5Co2O5+δ (SBSC), Ce0.6Mn0.3Fe0.1O2 (CMF), and La0.9Sr0.1Ga0.8Mg0.2O3-δ (LSGM), have been synthesized and characterized for the crystallinity, microstructure, conductivity, coefficient of thermal expansion properties were studied. The material application to form an SOFC has been executed and cell performances are investigated as well.
