Abstract
Abstract An ozone generating device having a plurality of interleaved ground and high potential electrodes mounted in spaced relation with their faces opposed. The faces of each electrode are encapsulated between a pair of uniformly distributed low stress glass plates which are adhered to the faces of the electrode by a moisture impervious and ozone resistant flexible bonding material such as silicone rubber. Spacers are inserted between opposed glass plates to form passageways for air to be ozonized by an alternating electrical field between the electrodes. A low impedance transformer with closely spaced primary and secondary windings is used to supply an alternating current to the electrodes. A plurality of the ground and high potential electrodes are assembled into a cell which is encapsulated in an outer enclosure by a moisture impervious ozone resistant material such as silicone rubber. The use of a moisture impervious ozone resistant material to fabricate the electrode assemblies and encapsulate the cell reduces the tendency for arcing to occur between the electrodes and thereby materially increases the useful life of the cell.
