Abstract
An ozone generator cell of a novel design includes a thin ceramic sheet sandwiched between a perforated metallic sheet serving as discharge electrode and a water-cooled aluminum base. Dry air or oxygen is passed over the electrode surface and a high-voltage, high-frequency electric field is applied between the electrode and the base for a corona discharge.
