Patent ID: 8328998

Claim:
An ozone generating method comprising: providing a pair of electrodes with a discharge space therebetween; producing a discharge by the application of an ac voltage between the pair of electrodes; providing at least one dielectric between said pair of electrodes; providing at least one low-resistance element between at least one of said pair of electrodes and said discharge space, the at least one low-resistance element being distinct from the at least one dielectric, in contact with said discharge, and having a surface resistivity of 10 4 Ω to 10 11 Ω; and providing a source gas containing oxygen into the discharge space in which said discharge is produced to generate ozone by the action of said discharge, the source gas provided into said discharge space including ultrapure oxygen having a purity of not less than 99.9%, wherein the low-resistance element is made of tungsten oxide.
