Patent ID: 7943098

Claim:
An apparatus for generating ozone and/or O 1 by the chemical conversion of an input oxygen containing gas comprising a housing defining a cavity therein, a fluid flow passage disposed in said cavity, said fluid flow passage being electrically insulated from said housing, a plurality of electrodes disposed in said fluid flow passage, each of said electrodes comprising a folded or welded multipoint mesh metal sheet disposed in a plurality of substantially overlapping layers, said fluid flow passage comprising a generally serpentinely extending passage including a plurality of passage segments, each said passage segment having one of said electrodes disposed therein, a power source for supplying an AC voltage, said power source including a contact lead electrically coupled to each said at least one electrode, and a ground lead in electrical contact with ground, a gas inlet extending through said housing and for providing gaseous fluid communication with a first portion of said flow passage upstream from said electrode, a gas outlet passage extending through said housing and providing gaseous fluid communication with a second portion of said flow passage spaced downstream from said electrodes.
