a Cross-sectional image of the Re-SOC with ME-PBSCC oxygen electrode after electrochemical evaluation. b Typical I–V–P curves of the single cell with ME-PBSCC oxygen electrode in FC mode using wet H2 and ambient air. c EIS curves of the single cell with ME-PBSCC oxygen electrode at 750–600 °C. d Ro and Rp of the single cells with ME-PBSCC and PBS32C oxygen electrodes. e The I–V–P curves and corresponding EIS at 0.5 A cm−2 (inset) of the single cells with ME-PBSCC and PBS32C at 700 °C under Cr-containing conditions. f The ratios of attenuated Pmax after the introduction of Cr contamination. g Durability of the cells operated at 0.5 A cm−2 and 700 °C when the ME-PBSCC and PBS32C oxygen electrodes were exposed to ambient air, air+3% H2O + Cr, and air+3% H2O, respectively.
