Mo-doped Ba0.5Sr0.5Co0.8Fe0.2O3-δ as a high-performance symmetric electrode for solid oxide fuel cells
Source abstract
Abstract
The perovskite oxide Ba 0.5Sr 0.5(Co 0.8Fe 0.2) 0.8Mo 0.2O 3-δ (BSCFM) is used as both an anode and cathode in symmetrical solid oxide fuel cells (SSOFCs) because of its high electrocatalytic activity for both oxygen reduction reaction and fuel oxidation. Doping with Molybdenum (Mo) not only stabilizes the structure of Ba 0.5Sr 0.5Co 0.8Fe 0.2O 3-δ (BSCF) to improve the redox stability, it also dramatically enhances its electrochemical performance and thermal expansion compatibility. At 800 °C, the area specific polarization resistance (ASR p) for the BSCFM symmetric cell with La 0.8Sr 0.2Ga 0.8Mg 0.2O 3-δ (LSGM) electrolyte is 0.064 Ω cm 2 and the maximum power density can reach 1225 mW cm −2 with wet H 2 (3 % H 2O) as fuel.
