A method is described for reducing carbon dioxide to a product comprising the steps of: providing carbon dioxide to a catholyte chamber of a reaction cell; providing water to an anolyte section of the reaction cell, forming a passageway through the reaction cell with a dual porosity cathode between the passageway and catholyte chamber and with a porous anode between the passageway and anolyte chamber; provides an electrolyte in a manner so that it passes through the passageway; and provides a direct current voltage across the dual porosity cathode and anode so as to cause a reduction of the carbon dioxide in cooperation with the electrolyte and hydrogen ions passing through the anode. This passes to a product contained within the electrolyte and causes oxygen to be emitted from the anolyte chamber.
