Abstract:
An object of the present invention is to provide a carbon dioxide enrichment device that has high enrichment performance, and also enables a significant reduction in energy required during driving. Provided is a carbon dioxide enrichment device, comprising: a first gas diffusion electrode 1; a second gas diffusion electrode 2 separated from the first gas diffusion electrode 1; and an electrolytic solution 3 existing between the first gas diffusion electrode 1 and the second gas diffusion electrode 2 to be in contact with the first gas diffusion electrode 1 and the second gas diffusion electrode 2, wherein the electrolytic solution 3 contains a solvent and a solute dissolved in the solvent, and the solute is dissolved in the solvent to form a dissolved inorganic carbon containing at least one of carbonic acid, hydrogen carbonate ions, and carbonic acid ions; oxygen is consumed by an oxygen reduction reaction on the first gas diffusion electrode 1, whereby a dissolved inorganic carbon is formed by a dissolution and ionization reaction of carbon dioxide in the solvent; the dissolved inorganic carbon derived from the solute or the dissolved inorganic carbon formed on the first gas diffusion electrode 1 is transported to the second gas diffusion electrode 2; and oxygen is formed from the solvent in the vicinity of the second gas diffusion electrode 2 by an oxidation reaction of the solvent on the second gas diffusion electrode 2, and carbon dioxide is formed from the dissolved inorganic carbon.
