CARBON DIOXIDE IMMOBILIZATION UNIT
First Claim
1. A carbon dioxide immobilization unit comprising at least:
- a first electrode decomposing water to produce protons;
a second electrode producing an organic acid or a carbohydrate from the protons produced in the first electrode and carbon dioxide; and
a proton conductor transferring the protons produced in the first electrode to the second electrode,wherein an oxidoreductase is present on a surface of the first electrode or a surface of the second electrode, or both.

Abstract
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 and a cathode both having a surface where an oxidoreductase is present are disposed to face each other with a proton conductor in between. Then, when electric power is externally supplied to the carbon dioxide immobilization unit, in the anode, water is decomposed to produce protons, and in the cathode, an organic acid or a carbohydrate is produced from the protons produced in the anode and carbon dioxide. At this time, while a carbon dioxide supply section supplies a high concentration of carbon dioxide to the cathode, oxygen produced in the anode and the organic acid or hydrocarbon produced in the cathode are removed from a reaction system through an oxygen removal section and a product recovery section, respectively.
