Abstract: Provides an imperforate valve metal blanket between the cell base of a diaphragm electrolysis cell and the cell can, which acts as a conductor from the positive current leads to dimensionally stable anodes and provides hollow anodes with perforate and imperforate sections to promote anolyte circulation within the cell.
Abstract: A cathode for electrolysis reactions comprising an electrically conductive electrode base having an outer coating on at least a portion of its exterior of an alloy of palladium and either silver or lead, process for the preparation of said cathodes and a method of electrolysis using said cathode.
Abstract: Repaired electrodes for use in diaphragm cells, electrowinning cells and the like comprising an elongated supporting riser having at least a surface coating of valve metal, at least a portion of a generally planar dimensionally stable previously used coated active electrode member bonded to said riser coating, a generally planar electrode member having a new electrocatalytic coating thereon secured to at least one of said riser coating or a portion of said previously used electrode.
