Abstract (en)
A CO<sub>2</sub>RR (reduction reaction) and a CO<sub>2</sub>RR electrochemical cell (2) is provided, comprising a three-phase boundary (14) having: a gaseous CO<sub>2</sub> diffused at least partially through a porous cathode (8), a solid catalyst (10) operatively associated with the cathode (8), and a catholyte (12) or membrane (16) in communication with the catalyst (10); a pressure controller (30) adapted to control back pressure within, at or near the three-phase boundary (14); and a reaction product of the CO<sub>2</sub>RR selected from the group consisting of: hydrocarbon, alcohol, H<sub>2</sub> and CO.
