Abstract
Provided are an anode for an ion exchange membrane electrolyzer which enables an aqueous solution of an alkali metal chloride to be electrolyzed at a lower voltage than a conventional anode and allows the concentration of an impurity gas included in an anode gas to be reduced and an ion exchange membrane electrolyzer using the same. The anode is an anode for an ion exchange membrane electrolyzer to be used in an ion exchange membrane electrolyzer that is separated by an ion exchange membrane into an anode chamber and a cathode chamber. The anode for an ion exchange membrane electrolyzer comprises at least one perforated flat metal plate 1 (expanded metal 1) and the thickness of the perforated flat metal plate 1 (expanded metal 1) ranges from 0.1 to 0.5 mm and the ratio of the short way SW to the long way LW (SW/LW) ranges from 0.45 to 0.55. The short way SW is preferably not more than 3.0 mm.
