An electrolytic ozone generator comprises a cavity, and electrodes and a membrane disposed in the cavity. The electrodes comprise an anode and a cathode. A water inlet and a water outlet are formed in two ends of the cavity respectively. The membrane has a side face parallel and opposite to the anode and a side face parallel and opposite to the cathode. An annular guide channel is formed between a periphery of the anode, the cathode and the membrane, and an inner wall of the cavity. A water distribution space is formed between the water inlet and the electrode at the water inlet end, and is communicated with the annular guide channel and the through holes in the electrode at the water inlet end. The anode and the cathode are electrically connected through water flowing therethrough. The ozone generator can increase the ozone concentration in water.

A novel cell for generating ozonated water including an integrated ozone concentration detector. 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. The cathode and anode have an array of holes allowing fluid to penetrate to the surface of the niobium membrane. Ozonated water from the anode is channeled to a spectrophotometer integrated within the housing. The spectrophotometer creates a signal representative of the ozone concentration in the ozonated water which is utilized by control circuitry in a closed loop to maintain a stable target concentration. A bubble trap may be integrated within the housing through which the ozonated water passes before entering the spectrophotometer to remove bubbles form the ozonated water. Input ports allow fluid to flow into the housing and over the anode and cathode and then out of the housing through outlet ports.
