Electrochemical methane conversion in a cell with the solid oxygen-conducting electrolyte (CH4, Pt\0.9ZrO(2) + O.1Y(2)O(3)\Pt + PrO2, air) was studied. The platinum electrode was found to be an active electrode/catalyst for partial methane oxidation to syngas with the ratio [H-2]/[CO] approximate to 2. At 800 degrees C, the selectivity to carbon monoxide formation and its yield reach 80 and 65%, respectively. At 660-700 degrees C, electrochemically generated oxygen oxidizes methane to syngas more efficiently than oxygen adsorbed from the gas phase. New possibilities and advantages of the electrochemical route of methane oxidation to syngas were compared to the same process in a normal kinetics mode.
