Membrane electrode assembly design to prevent CO(2) crossover in CO(2) reduction reaction electrolysis

To reach a net-zero energy economy by 2050, it is critical to develop negative emission technologies, such as CO(2) reduction electrolyzers, but these devices still suffer from various issues including low utilization of CO(2) because of its cross-over from the cathode to the anode.

Sumario:To reach a net-zero energy economy by 2050, it is critical to develop negative emission technologies, such as CO(2) reduction electrolyzers, but these devices still suffer from various issues including low utilization of CO(2) because of its cross-over from the cathode to the anode. This comment highlights the recent innovative design of membrane electrode assembly, utilizing a bipolar membrane and catholyte layer that blocks CO(2) cross-over and enables high CO(2) single-pass utilization.
