Abstract

The present invention provides improved cathodes and industrialized methods for producing such cathodes using an industrial dosing valve-based electrode coating fluid emitting technique. The family of cathodes according to the present invention can be produced so that they inhabit a pre-existing metallic surface such as an inner surface of a titanium casing adjacent but insulated from direct electrical communication from an anode. Foil-type valve metal anodes as well as porous valve metal anodes formed from metallic powders may be used in conjunction with the cathodes of the present invention.
