Abstract
A system and method for feeding carbon dioxide to a first cathode cavity of a first electrochemical cell, electrochemically reducing the carbon dioxide at a first cathode in the first electrochemical cell to carbon monoxide (CO), flowing the CO from the first cathode cavity to a second cathode cavity of a second electrochemical cell, and forming at least one of ethanol or ethylene from the CO at a second cathode in the second electrochemical cell. The forming of the at least one of ethanol or ethylene from the CO may involve dimerization of the CO at the second cathode to form CO dimer.
