Abstract

Novel perovskite-type La_0.3Sr_0.7Fe_0.7Ti_0.3O₃ (LSFT) oxide is investigated as both anode and cathode materials in a symmetrical solid oxide electrolysis cell (SOEC) for direct electrolysis of pure CO₂ at 800 °C. The current density is 521 mA cm^− 2 at an applied voltage of 2.0 V. The lowest polarization resistance R_p of this symmetrical SOEC is obtained at 2.0 V with a value of as low as 0.08 Ω cm², which is much lower than that of other perovskite and Ni-cermet cathode. LSFT cathode also shows excellent durability in pure CO₂ electrolysis, especially at high voltage of 2.0 V. Our results indicate that the LSFT is a promising alternative electrode material for CO₂ electrolysis.
