Abstract (en)

[origin: EP2594664A1] There is provided a carbon dioxide immobilization unit capable of easily immobilizing carbon dioxide in the form of an organic acid or a carbohydrate under a normal environment. An anode 1 and a cathode 2 both having a surface where an oxidoreductase is present are disposed to face each other with a proton conductor 3 in between. Then, when electric power is externally supplied to the carbon dioxide immobilization unit, in the anode 1, water is decomposed to produce protons, and in the cathode 2, an organic acid or a carbohydrate is produced from the protons produced in the anode 1 and carbon dioxide. At this time, while a carbon dioxide supply section 5 supplies a high concentration of carbon dioxide to the cathode 2, oxygen produced in the anode 1 and the organic acid or hydrocarbon produced in the cathode 2 are removed from a reaction system through an oxygen removal section 4 and a product recovery section 6, respectively.
