Patent ID: 7695691

Claim:
A discharge cell for an ozonizer, comprising: a module-stacked body constituted by stacking a plurality of cell modules in a direction of plate thickness wherein a plate shaped cell unit is one module, the module-stacked body being accommodated in a tank to which raw material gas is supplied to introduce raw material gas to a discharge gap of the plural cell modules to produce ozone, the discharge gaps formed by a plate-like first electrode, a dielectric body and a second electrode, wherein the first electrode includes a cooler provided with coolant circulation, the cooler being a thin plate shaped cooler where a coolant path is formed between flat metal plates by stacking the flat metal plates in a direction of plate thickness; wherein a manifold way for coolant supply and a manifold way for coolant exhaust which are shared between each cooler are formed in the module-stacked direction in the module-stacked body; and wherein a manifold way for ozone gas, which is shared between each cell module, is formed in the stacked direction in the module-stacked body so as to take out ozone gas generated in the discharge gap of each cell module to outside an apparatus.
