摘要：

Y-doped BaZrO3/NaOH composites were designed and fabricated with ZnO as sintering aid. Electrical conductivities of the composites were measured in moist hydrogen by a four-probe DC method. Microstructure of samples was observed by SEM. The results revealed that ZnO effectively lowered the sintering temperature of the system. Unfortunately, it had a negative effect on the electrical conductivity. The incorporation of NaOH in the composites greatly improved their proton conductivities.
