Abstract

The electrolysis of CO₂ has been examined in a solid oxide electrolyzer (SOE) using a ceramic electrode based on La_0.8Sr_0.2Cr_0.5Mn_0.5O₃ (LSCM), infiltrated into a yttria-stabilized zirconia scaffold together with 0.5 wt % Pd supported on 5 wt % Ce_0.48Zr_0.48Y_0.04O₂. An SOE with this electrode exhibited a total cell impedance of 0.36 Ω cm² at 1073 K for operation in CO-CO₂ mixtures. An additional benefit is that the CO-CO₂ electrode was shown to be redox stable, with LSCM exhibiting good conductivity in both oxidizing and reducing environments, so that the cell can operate in pure CO₂.
