Development of the syngas production from solid oxide H2O/CO2 co-electrolysis is limited by the intensive energy input and low efficiency. Here, we present a new concept to efficiently generate syngas in both sides of the solid oxide electrolyzer by synergistically combining co-electrolysis with partial oxidation of methane (POM). Thermodynamic calculation and electrochemical measurements for the POM assisted solid oxide co-electrolysis processes on the SFM-SDC/LSGM/SFM-SDC cells exhibited an reduced electric input, increased energy conversion efficiency and decreased cathodic co-electrolysis polarization resistance in comparison with the conventional co-electrolysis. This method will be crucial to establish a clean and effective energy conversion system to meet global sustainable energy needs. (C) 2014 Elsevier B.V. All rights reserved.
