Abstract

Ce(0.8)Gd(0.05)Y(0.15)O(1.9)(GYDC) electrolyte was prepared by a carbonate co-precipitation method. Lithium nitrate at 1, 1.5, 2 and 3 mol% was added to GYDC as sintering additive. 96% relative density was achieved for GYDC at sintering temperature of 800 degrees C with addition of 1.5 mol% LiNO(3). The conductivities of GYDC with sintering aids LiNO3 were measured by a.c. impedance spectroscopy and showed comparable values to that of pure GYDC sample sintered at 1400 degrees C. A single cell with 1.5 mol% LiNO(3) infiltrated GYDC electrolyte was fabricated by sintering at 800 degrees C for only 2 h. Lithiated NiO was synthesized by the glycine-nitrate combustion method and employed as cathode material. The cell was tested at temperatures from 500 to 575 degrees C and a maximum power density of 73 mW cm(-2) was obtained at 575 degrees C. These preliminary results indicate that LiNO(3) is a very effective sintering additive for intermediate temperature solid oxide fuel cell fabrication.
