US Patent:

48805173, Nov 14, 1989

Filed:

Jun 2, 1987

Appl. No.:

7/057592

Inventors:

John E. Bennett - Painesville OH
Donald S. Novak - Chardon OH
Thomas A. Mitchell - Mentor OH

Assignee:

ELTECH Systems Corporation - Boca Raton FL

International Classification:

G23F 1300

US Classification:

204196

Abstract:

A catalytic polymer electrode compries a current conducting polymer body forming an electrode base which is provided with catalytic valve metal particles fixed to its surface. A current conducting body of carbon filled thermoplastic polymer is heated to soften its outer surface, and the catalytic valve metal particles are pressed onto its softened surface and thereby attached to the surface of the polymer body. Such a catalytic polymer electrode used as an anode in an impressed-current cathodic protection system comprises a catalyst to provide a reduced oxygen potential. Such catalytic polymer anodes may be applied in systems for impressed current cathodic protection of reinforced concrete structures, such as bridge decks, support members, parking garages, or of buried or submerged steel structrues such as gas and oil pipelines, offshore production platforms, fuel storage tanks, well casings.

International Classification:

C25B 900

US Classification:

204252

Abstract:

An apertured and porous metal article can find use, for example, in diaphragm or membrane electrolysis cells. The article may comprise a thin and flexible metal foam of small pores which, typically, has been perforated with large apertures. The article may also be provided with an electrocatalytic coating. It can be in substantial physical contact with a membrane or diaphragm separator used in the cell for separating anode and cathode members or compartments. There is also disclosed the preparation of the article and an electrolysis cell utilizing the resulting apertured and porous metal article.
