There is provided an electrolysis device configured to use unpurified water containing a small amount of ions of alkaline earth metal such as Ca and Mg as raw water, and to have a structure of supplying the raw water to a cathode chamber in which deposition of scale of the alkaline earth metal on the surface of a cathode provided in the cathode chamber can be prevented. The electrolysis device and the apparatus for producing electrolyzed ozone water are configured by an electrolysis cell formed in a manner that a membrane-electrode assembly is configured by a solid polymer electrolyte separation membrane formed by a cation exchange membrane, and an anode and a cathode which are respectively adhered to both surfaces of the solid polymer electrolyte separation membrane, and the membrane-electrode assembly is compressed from both surfaces thereof, and thus the solid polymer electrolyte separation membrane, the anode, and the cathode are adhered to each other. A porous conductive metallic material having flexibility and having multiple fine voids therein is used as the cathode, and scale which is mainly formed of hydroxide of alkaline earth metal is stored in fine voids in the cathode, and thus localized deposition of hydroxide of the alkaline earth metal at a contact interface between the cathode and the solid polymer electrolyte separation membrane is prevented.

A device for generating an ozone in a high moisture content environment is provided. The ozone generator features an enclosure with an interior space, an assembly within this interior space, at least one sheet of glass, and a power control board positioned in the housing and which houses the at least one sheet of glass.

A novel cell for generating ozonated water, the cell comprises a nafion membrane separating a diamond coated anode, and a gold surfaced cathode enclosed within a cell housing with the catalyst side of the nafion membrane facing the cathode. The cell housing has a cathode housing portion and an anode housing portion separated by the membrane, each housing portion having ridges to enhance substantially even flow of fluid over the cathode and anode. The housing portions contain O-rings in grooves to prevent leaks, and alignment features to keep the electrodes aligned. The cathode and anode have an array of holes allowing fluid to penetrate to the surface of the niobium membrane. Input ports allow fluid to flow into the housing and over the anode and cathode and then out of the housing through outlet ports. The housing may also incorporate an integrated spectral photometer including a bubble trap.
