The electrolysis of CO2 has been examined in a solid oxide electrolyzer (SOE) using a ceramic electrode based on La0.8Sr0.2Cr0.5Mn0.5O3 (LSCM), infiltrated into a yttria-stabilized zirconia scaffold together with 0.5 wt % Pd supported on 5 wt % Ce0.48Zr0.48Y0.04O2. 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… CONTINUE READING
