Abstract:
The electrolyte of a solid oxide electrolysis cell (SOEC), La0.8Sr0.2Ga0.2Mg0.2O3-δ (LSGM), can operate at
intermediate temperatures but has poor stability. To enhance the stability of LSGM, Sm0.2Ce0.8O1.9, (SDC) and Gd0.1Ce0.9O1.95 (GDC) are added or coated. In this study, LSGM was synthesized, and phase formation was investigated. The LSGM synthesis observes the same instructions as commercial-grade LSGM. LSGM synthesis was found to be
similar to commercial-grade, but slightly smaller, with impurities including LaSrGaO4 and LaSrGa3O7. In SEM/EDX characterization, the LSGM synthesis had a crystalline shape, and the distribution of each element was similar to a
commercial grade. The LSGM pellet was sintered for 10 hours at 1450 °C. The crystallite size increases with increasing sintered temperature. Sintering at higher temperatures than LSGM synthesis increases the crystallite size of the LSGM pellet and removes moisture and organic material in the LSGM pellet.
