  • Three-dimensional electrode for electrolysis, ion exchange membrane electrolytic cell and method of electrolysis using three-dimensional electrode
    Patent number: 7927471
    Abstract: A three-dimensional electrode with higher strength and higher toughness is provided. The three-dimensional electrode is fabricated by bending a plurality of snicks which are formed in a plate-like electrode substrate toward the same direction. The stabilization of the positional relation among the elements generated by the three-dimensional electrode neither mechanically damages the membrane nor causes the insufficient current supply. The three-dimensional electrode is preferably used for brine electrolysis and white liquor electrolysis.
    Type: Grant
    Filed: September 25, 2006
    Date of Patent: April 19, 2011
    Assignee: Chlorine Engineers Corp., Ltd.
    Inventors: Yoshitsugu Shinomiya, Masahiro Ohara, Keiji One, Tsuneo Tokumori
