The present invention provides for the electrochemical generation of ozone for use in "point-of-use" applications. The electrochemical ozone generators or systems of the present invention may be used to provide disinfected water, ozone-containing water, and/or ozone gas. Disinfected water may be produced by introducing ozone gas into a potable or purified water source for the purpose of disinfecting or controlling the microorganisms in the water source. Ozonated water or ozone gas may be produced and provided for various anti-microbial and cleansing applications of the consumer, such as washing food, clothing, dishes, countertops, toys, sinks, bathroom surfaces, and the like. Furthermore, the ozone generator may be used to deliver a stream of ozone-containing water for the purpose of commercial or residential point-of-use washing, disinfecting, and sterilizing medical instruments and medical equipment. For example, the ozone-containing water may be used directly or used as a concentrated sterilant for the washing, disinfecting, and sterilizing of medical instruments or equipment. Ozone gas may also be used in many of the foregoing examples, as well as in the deodorization of air or various other applications. The invention allows the electrochemical ozone generator to operate in a nearly or entirely passive manner with simplicity of design.
