Carbon Dioxide Reduction Device

Abstract

A carbon dioxide reduction device includes: an oxidation electrode that receives light from the outside; an oxidation bath that holds an electrolytic solution in which the oxidation electrode is immersed; an electrolyte membrane that constitutes a part of one surface of the oxidation bath excluding a surface on which the light is incident; a reduction electrode that is connected to the electrolyte membrane; a reduction unit in which the reduction electrode is disposed and to which a gas containing carbon dioxide is supplied from the outside; and a blower that generates an airflow toward the reduction electrode inside the reduction unit. The reduction electrode has a plate shape, and one surface of the reduction electrode is in contact with the electrolyte membrane.
