A High Electrochemical Performance Proton Conductor Electrolyte with CO2 Tolerance

Youmin Guo; Ye Lin; Huangang Shi; Ran Ran; Zongping Shao

Abstract A low-temperature proton conductor electrolyte with CO 2 tolerance that had a smaller drop in performance with decreasing operation temperature was developed. A Ni-anode-supported solid oxide fuel cell (SOFC) comprising a proton-conducting BaZr 0.4 Ce 0.4 Y 0.2 O 3 (BZCY4) electrolyte and a Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3 (BSCF) perovskite cathode was fabricated. An anode-supported thin-film electrolyte fuel cell was fabricated by the dual dry pressing/sintering process. A peak power density of 219 mW/cm 2 was achieved at 750 °C while it still was 57 mW/cm 2 at 400 °C when operating on humidified H 2 fuel using a cell with a 32 μm thick electrolyte.
