Patent number: 9045839Abstract: The present techniques provide electrochemical devices having enhanced electrodes with surfaces that facilitate operation, such as by formation of a porous nickel layer on an operative surface, particularly of the cathode. The porous metal layer increases the surface area of the electrode, which may result in increasing the efficiency of the electrochemical devices. The formation of the porous metal layer is performed in situ, that is, after the assembly of the electrodes into an electrochemical device. The in situ process offers a number of advantages, including the ability to protect the porous metal layer on the electrode surface from damage during assembly of the electrochemical device. The enhanced electrode and the method for its processing may be used in any number of electrochemical devices, and is particularly well suited for electrodes in an electrolyzer useful for splitting water into hydrogen and oxygen.Type: GrantFiled: June 10, 2008Date of Patent: June 2, 2015Assignee: General Electric CompanyInventors: Guillermo Daniel Zappi, Kenneth Paul Zarnoch, Christian Andrew Huntley, Dana Ray Swalla

Patent number: 6328875Abstract: Electropurification of contaminated aqueous media, such as ground water and wastewater from industrial manufacturing facilities like paper mills, food processing plants and textile mills, is readily purified, decolorized and sterilized by improved, more economic open configuration electrolysis cell designs with electrodes comprising a plurality of conductive porous elements in electrical contact with one another. The cells may be divided or undivided, and connected in monopolar or bipolar configuration. When coupled with very narrow capillary gap electrodes more economic operation, particularly when treating solutions of relatively low conductivity is assured. The novel cell design is also useful in the electrosynthesis of chemicals, both organic and inorganic types, such as hypochlorite bleaches and other oxygenated species.Type: GrantFiled: November 4, 1999Date of Patent: December 11, 2001Assignee: Zappi Water Purification System, Inc.,Inventors: Guillermo Daniel Zappi, Norman L.
