초록

High temperature co-electrolysis of H2O-CO2 mixtures using solid oxide cells has attracted attention as promising CO2 utilization technology for production of syngas (H2/CO), feedstock for E-fuel synthesis. For direct supply to E-fuel production such as hydrocarbon and methanol, the outlet gas ratio (H2/CO/CO2) of co-electrolysis should be controlled. In this work, current voltage characteristic test and product gas analysis were carried out under various reaction conditions which could attain proper syngas ratio.
