Characterization of scandia stabilized zirconia prepared by glycine nitrate process and its performance as the electrolyte for IT-SOFC
D Lee, I Lee, Y Jeon, R Song - Solid State Ionics, 2005 - Elsevier
Zirconia stabilized with 8 mol% scandia (8ScSZ) powder was synthesized using glycine
nitrate process (GNP) for use as the electrolyte of an intermediate temperature solid oxide
fuel cell (IT-SOFC). The powder was compacted into a disc and sintered at 1600° C for 6 h in
air for characterization. 8ScSZ consisted of a mixture of cubic and tetragonal phases after
sintering. It showed four times as high electrical conductivity (0.159 S/cm) as 8YSZ (0.039
S/cm) at 800° C. The reactivity of 8ScSZ in contact with La0. 6Sr0. 4Co0. 2Fe0. 8O3 turned …
