- Abstract
- Co doping was used to enhance the electrical conductivity of La0.8Sr0.2Ga0.8Mg0.2O3-partial derivative (LSGM). La0.8Sr0.2Ga0.8Mg0.2-xCoxO3-partial derivative (LSGMC) powders were synthesized using the glycine nitrate process for use as the electrolyte of solid oxide fuel cells. The powder X-ray diffraction patterns confirmed a single perovskite phase and the SEM images showed the dense grain microstructure of the sintered pellets. The electrical conductivity of LSGMC measured at 800 degrees C was observed to be 0.145 Scm(-1), which is higher than that of LSGM (0.127 Scm(-1)). In addition, the linear thermal expansion coefficient and chemical reaction were investigated. (C) 2011 The Electrochemical Society. [DOI: 10.1149/1.3597839] All rights reserved.
