Filed:

Apr 1, 1998

Appl. No.:

9/053154

Inventors:

Albert R. Prasnikar - Madison OH
Richard C. Carlson - Euclid OH
Richard J. Coin - Chardon OH

Assignee:

ELTECH Systems Corporation - Chardon OH

International Classification:

C25B 1106

US Classification:

204290F

Abstract:

An electrode is disclosed having a coating on part of the electrode, e. g. , a front face, comprising the oxides of tin, antimony, at least one platinum group metal and at least one valve metal. Another part of the electrode, such as a back face, has a coating comprising the oxides of at least one valve metal and at least one platinum group metal. The electrode can be generally plate-shaped and most desirably has at least one chamfered corner. The electrode is particularly useful in a cell wherein brine electrolyte is electrolyzed to prepare a disinfectant solution containing hypochlorite. The disinfectant solution can be especially serviceable, such as in maritime application, for treating water, e. g. , freshwater as represented by desalinated water.
