摘要:
A carbon dioxide enrichment device includes first and second gas diffusion electrodes; an anion exchange membrane; and an electrolytic solution partitioned by the anion exchange membrane. The electrolytic solution contains solvent and solute, and the solute is dissolved to form a dissolved inorganic carbon containing carbonic acid, hydrogen carbonate ions, or carbonic acid ions. The oxygen is consumed by an oxygen reduction reaction on the first gas diffusion electrode, whereby, a dissolved inorganic carbon is formed by a dissolution and ionization reaction of carbon dioxide in the solvent. The dissolved inorganic carbon from the solute or the dissolved inorganic carbon is transported to the second gas diffusion electrode through the anion exchange membrane, and oxygen is formed from the solvent near the second gas diffusion electrode by an oxidation reaction of the solvent on the second gas diffusion electrode, and carbon dioxide is formed from the dissolved inorganic carbon.
