Abstract

The present invention provides a carbon dioxide-generating electrode apparatus made up of a carbon anode, the upper end part thereof being fixed to a terminal part, and a cathode disposed in a non-contacting relationship so as to face the carbon anode, characterized in that the distance between the carbon anode and the cathode is broadened relatively and continuously from the lower part toward the upper part. The distances between the carbon anode and the cathode are set to be an equal distance at positions on the same horizontal cross section, and the difference (W.sub.1 -W.sub.2) between a distance (W.sub.1) between the side face at the upper end part of the carbon anode and the inner face of the cathode from a distance (W.sub.2) between the side face at the lower end part of the carbon anode 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 provides the stable generation of carbon dioxide over a long period of time by an electrolytic operation with a fixed current.
