In present work, the perovskite BaCe0.85-xZrxY0.15O3-λ (BCZY, x = 0.1, 0.3, 0.5, and 0.7) were synthesized via solid state reaction (SSR) and adopted as an electrolyte materials for PCFCs. Powder characteristics were examined using X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Brunauer, Emmett and Teller (BET) surface area analysis. Single phase BCZY were obtained in all compositions, and chemical stability was improved with increasing Zr content. Anode-supported cell with Ni-BaCe0.55Z0.3Y0.15 O3-λ (BCZY3) anode, BCZY3 electrolyte and BCZY3-Ba0.5Sr0.5Co0.8Fe0.2O3-λ (BSCF) composite cathode was fabricated and electrochemically characterized. Open-circuit voltage (OCV) was 1.05 V, and peak power density of 370 (mW/cm2) was achieved at 650°C.
