Carbon dioxide-generating electrode apparatus

摘要

The present invention provides a carbon dioxide-generating electrode apparatus comprising an anode carbon, the upper end part thereof being fixed to a terminal part, and a cathode placed in a non-contact state so as to face the anode carbon, characterized in that a distance between the anode carbon and the cathode is broadened relatively and continuously from the lower part toward the upper part. The distances between the anode carbon and the cathode are set to an equal distance in the positions on the same horizontal cross section, and the difference (W1 - W2) of a distance (W1) between the side face at the upper end part of the anode carbon and the inner face of the cathode from a distance (W2) between the side face at the lower end part of the anode carbon and the inner face of the cathode is preferably set to a range of 1.0 to 5.0 mm. A carbon dioxide-generating electrode apparatus according to the present invention secures the always stable generation of carbon dioxide over the long period of time by an electrolytic operation with a fixed current.
