  • Publication number: 20240093388
    Abstract: Proposed is a CO2-reduction membrane electrode assembly (MEA), which is a novel MEA capable of changing a reaction condition to an alkaline condition from a problematic acidic condition unfavorable to reactions on a cathode side during catalytic reactions using a cation exchange membrane (CEM) as a separator. In addition, the MEA can reduce a hydrogen evolution reaction (HER), which is a side reaction. In addition, a method of manufacturing the MEA, and a CO2-reduction assembly including the MEA are also proposed.
