    Abstract

    High-temperature proton conductors are promising electrolytes for protonic solid oxide fuel cells (H+-SOFCs). In this study, the relationship between the Zr doping content and structure, chemical stability, carbon dioxide resistivity, sinterability and electrochemical properties of BaZryCe0.8-yY0.2O3-d (BZCYy), 0.0 = y = 0.8, are studied systemically using XRD, CO2-TPD, SEM, EIS and I-V polarization characterizations. Zr doping suppresses carbonate formation, CO2-TPD demonstrates that the formative rate of carbonate over BZCYy are 7.50 × 10-6 and 8.70 × 10-7 mol m-2 min-1 at y = 0.0 and 0.4, respectively. Investigation of sinterability shows that the anode-supported configuration helps the sintering of the thin-film electrolyte. Peak power densities of 220 and 84 mW cm-2 are obtained at 750 and 450 °C, respectively, with BZCY0.4 electrolyte. Due to the favorable chemical stability against CO2 and good sintering in the thin-film configuration, BZCY0.4 is a potential electrolyte material for H+-SOFCs. © 2009 Elsevier B.V.
