Abstract: Sr1.95Pr0.05Fe1.5Mo0.5O6-? (SPFM) powder synthesized by combustion method was uniformly compounded with Ce0.8Gd0.2O1.9 (GDC) powder obtained by sol-gel route to prepare GDC-SPFM heterogeneous structure composite electrolytes with 10, 15, 20 and 30 wt.% of SPFM. The crystal structure, micro-morphology and electrochemical performance were investigated. The results show that GDC and SPFM have good chemical compatibility and the prepared GDC-SPFM composites have high ionic conductivity at low temperature. The GDCSPFM composite electrolyte based on 30wt.% SPFM achieved the best performance at 800?C and the ionic conductivity of this sample reached 0.07 S/cm.
