A composite electrolyte, Zr doped BaCe0.8Y0.2O3-δ(BaCe0.5Zr0.3Y0.2O3-δ,BCZY) and binary carbonates [(Li,Na)2CO3] (LNCO) was first applied to reduce CO2accompanied with steam electrolysis in solid oxide electrolysis cell (SOEC) at 600 °C, lower than which conventional SOEC composed by YSZ works in (usually above 800 °C). Electrolysis performances are improved due to sufficient steam feed at oxygen electrode side (30–110 ml/min). Steam electrolysis provides proton source for the reduction of CO2. Application of composite electrolyte promotes proton transport and directly leads to H2even CH4production. To a certain degree, carbon resistance guarantees the symmetric SOEC operation at a lower bias potential of 0.5 V (vs.OCV) applied. A redox-stable and carbon-tolerant LSCM as symmetric electrode with a hybrid-ion-conducting composite electrolyte realizes the fuel synthesis by CO2reduction in proton-type solid oxide electrolyzer.
