Membrane electrode assembly device for all-gas-phase carbon dioxide electrohydrogenation synthesis reaction

Abstract

The application discloses a membrane electrode stack device for all-gas-phase carbon dioxide hydrogenation electrosynthesis reaction, and relates to the technical field of electrocatalytic carbon dioxide reduction. The membrane electrode stack device comprises at least two membrane electrode units, a plurality of the membrane electrode units are sequentially arranged along a stacking direction and constitute a stack structure; an insulating sealing frame is arranged between two adjacent membrane electrode units, a through hole structure for fluid conduction is arranged on each insulating sealing frame, and the through hole structures jointly constitute a fluid header penetrating through the membrane electrode stack after the plurality of membrane electrode units are stacked along the stacking direction, so that the distribution and collection of reactant fluids of each membrane electrode unit are realized. The membrane electrode stack device in the application realizes stable stacking of the plurality of membrane electrode units and uniform distribution and collection of reactant fluids, and improves the internal reaction consistency and mass transfer efficiency of the stack.
