Popis:	Oxidative coupling of methane (OCM) is one of the most promising technologies for the effective use of methane. In this study, La0.3Sr0.7TiO3 was examined as an anode material for solid oxide electrolysis cell with OCM reaction. X-ray diffraction measurement was conducted for the material characterization, and alternating current impedance and current-voltage measurement were conducted for the cell characterization. The activity test was conducted at different current densities, and the anode gas compositions were analyzed. The electrochemical production rates of CO, CO2, C2H6, and C2H4 were increased linearly as the applied current voltages were increased, while the selectivities of all products were almost constant.
