Abstract
This invention provides a technology that allows for the determination of the electrical conductivity of a solution in a carbon dioxide concentration device. [Solution] The carbon dioxide concentration apparatus comprises an absorption unit that absorbs carbon dioxide in a process gas into a predetermined solution, and an electrochemical cell that generates a gas containing carbon dioxide at a higher concentration than the process gas from the predetermined solution that has absorbed carbon dioxide. The electrochemical cell comprises an anode, a cathode, an anode liquid chamber through which predetermined ions are supplied from the anode and through which the predetermined solution that has absorbed carbon dioxide flows, a cathode liquid chamber that supplies the predetermined solution to the cathode, the anode liquid chamber, and an electrolyte membrane provided between the cathode liquid chamber and the cathode liquid chamber. An electrical conductivity meter for measuring the electrical conductivity of the predetermined solution is provided inside the anode liquid chamber or the cathode liquid chamber, or in a passage connected to the anode liquid chamber or the cathode liquid chamber.
