520 _ _ |a Abstract: In this work, 20 mol.% of Ce was introduced into the lattice of Y-doped BaZrO3, and 0.5 wt.% of NiO was applied as a sintering aid. The Y2O3 substituent amount varies within the range of 10-30 mol.% in order to study the influence of Y on the phase formation, microstructure, hydration behavior, electrical performance, mechanical properties and thermo-chemical stability. The samples were prepared by solid state reaction combined with traditional sintering process at 1500 °C for 10h. Y-riched phase has been found in samples with Y content exceeding 20 mol.%. Excessive Y2O3 substitution has a negative impact on the grain boundary conductivity. The grain conductivity increases linearly with the increase in Y content (except for the sample with 30 mol.%. of Y). The impact of Y on proton conduction in the grain is revealed by integrating experimental and simulation results. This work provides comprehensive guidance for the selection of electrolyte composition for electrochemical devices.Acknowledgement: Chinese Scholarship Council (CSC); HGF Research Program “Materials and Technologies for the Energy Transition” (MTET) - Topic 3: Chemical Energy Carriers.
