Effects of La Content on the Densification, Microstructure, and Conductivity of Doped La10−x Ge6 O26±δ Electrolytes

Abstrakt

In this study, the influence of La content on the characteristics of Nb-, Mo-, and W-doped LaxGe6O26±δ electrolytes was investigated through sintering study, X-ray diffraction, scanning electron microscopy, and conductivity measurement. The densification of LaxGe5.5Nb0.5O26±δ and LaxGe5.5W0.5O26±δ was retarded as the x reached 9.75, while that of LaxGe5.5Mo0.5O26±δ improved with increasing La content. The average grain size slightly increased and weight loss due to evaporation of GeO2 significantly reduced with increasing La content, ranging from 1.39% to 0.26%. Among the systems studied, La9.33Ge5.5Nb0.5O26.245, La9.33Ge5.5Mo0.5O26.045, and La9.50Ge5.5W0.5O26.75 electrolytes revealed great potential for use in SOFC applications.
