Abstract

Pure water 3 is made to pass through a carbon dioxide contact mechanism, to become carbonated water, and is supplied to an ozone gas and hydrogen gas generation section, so that the concentration of generated ozone gas becomes stable. As a result, the concentration of the generated ozone gas is high and stable, and a high concentration can be maintained.

Claims (3)

1. An electrolytic gas generation device for generating ozone gas consisting essentially of: an anode chamber in which the ozone gas and oxygen is generated; a cathode chamber in which hydrogen gas is generated; a solid electrolyte ion exchange film separating the anode chamber from the cathode chamber; a porous anode provided at a first side of the ion exchange film in the anode chamber; a porous cathode provided at an opposite side of the ion exchange film in the cathode chamber; a power source for imposing a potential difference between the porous anode and the porous cathode; a pure water supply source for supplying pure water to a mixer; a carbon dioxide supply source for supplying carbon dioxide to the mixer; and the mixer for mixing the pure water and the carbon dioxide to form carbonated water and supplying the carbonated water to the anode chamber.

2. An electrolytic gas generation device according to claim 1 , wherein the mixing means in which the pure water is changed to carbonated water is such that pure water is introduced to one side of a film and carbon dioxide is introduced to an opposite side of the film, so that the carbon dioxide dissolves in the pure water via said film to change the pure water to carbonated water.

3. An electrolytic gas generation device according to claim 1 , wherein the carbonated water contains carbon dioxide.
