Abstract

Apatite-type lanthanum silicates have been successfully produced as the electrolyte materials for the intermediate temperature solid oxide fuel cells. In this paper, La 9.95 Ba 0.05 Si 5.8 Zn 0.2 O 26.775 co-doped lanthanum silicate electrolyte has been prepared by the conventional solid-state reaction method to investigate the structural, morphological and electrical properties of the electrolyte. The oxyapatite electrolyte has been characterized by X-ray diffraction, scanning electron microscopy and electrochemical impedance spectroscopy. Hexagonal apatite structure of La 9.95 Ba 0.05 Si 5.8 Zn 0.2 O 26.775 with space group P6 3 /m formed as the major phase after sintered at 1600°C for 8 hours. Total oxide ion conductivity of La 9.95 Ba 0.05 Si 5.8 Zn 0.2 O 26.775 ranges from 9.52 x 10 -6 to 2.86 x 10 -4 Scm -1 from 450 to 800C, respectively.
