Ion exchange membrane electrolyzer

1. An ion exchange membrane electrolyzer, in which an electric current is passed through at least one electrode while said electrode is in contact with a plurality of comb-like flat leaf spring tags extending at an angle from a flat leaf spring form of retainer member located on an electrode partition provided in an electrode chamber, wherein each pair of comb-like flat leaf spring tags are arranged in such a way that adjacent flat leaf spring tags extend in mutually opposite directions.

2. The ion exchange membrane electrolyzer according to claim 1 , wherein each pair of comb-like flat leaf spring tags extending in mutually opposite directions have the same length.

3. The ion exchange membrane electrolyzer according to claim 1 , wherein the flat leaf spring tags comprise abutments bent at tips toward the flat leaf spring form of retainer member, which abutments are in contact with the electrode.

4. The ion exchange membrane electrolyzer according to claim 1 , wherein openings are found on a surface of the flat leaf spring form of retainer member onto which a comb-like flat spring tag arrangement is projected, and a land portion of the retainer member is found on a surface of the retainer member onto which adjacent flat spring tags are projected.

5. The ion exchange membrane electrolyzer according to claim 1 , wherein openings are found on a surface of the flat leaf spring form of retainer member onto which a comb-like flat spring tag arrangement is projected, and a land portion of the retainer member is found on a surface of the retainer member onto which adjacent sets of flat leaf spring tags are projected.

6. The ion exchange membrane electrolyzer according to claim 1 , wherein the flat leaf spring form of retainer member is joined at a belt-like junction to a flat plate form of electrode chamber partition in a parallel relation thereto, thereby defining a space between the retainer member and the electrode chamber partition, said space being used as a downward flow path for an electrolyte, and an upward flow path for the electrolyte is formed on an electrode side.

7. The ion exchange membrane electrolyzer according to claim 2 , wherein the flat leaf spring form of retainer member with the flat leaf spring tags attached thereto is joined at a belt-like junction to a flat plate form of electrode chamber partition in a parallel relation thereto, thereby defining a space between the retainer member and the electrode chamber partition, said space being used as a downward flow path for an electrolyte, and an upward flow path for the electrolyte is formed on an electrode side.

8. The ion exchange membrane electrolyzer according to claim 1 , wherein the flat leaf spring form of retainer member with the flat leaf spring tags attached thereto is joined to a porous member having an opening a diameter of which is larger than the electrode that the flat leaf spring tags contact.

9. The ion exchange membrane electrolyzer according to claim 2 , wherein the flat leaf spring form of retainer member with the flat leaf spring tags attached thereto is joined to a porous member having an opening a diameter of which is larger than the electrode that the flat leaf spring tags contact.

10. The ion exchange membrane electrolyzer according to claim 3 , wherein the flat leaf spring form of retainer member with the flat leaf spring tags attached thereto is joined to a porous member having an opening a diameter of which is larger than the electrode that the flat leaf spring tags contact.
