<P>PROBLEM TO BE SOLVED: To uniformly and appropriately keep the interface concentration between a flexible cathode and an ion exchange membrane, in a zero-gap electrolytic cell having such a constitution that an anode, the ion exchange membrane, and the flexible cathode are closely arranged, and a cushion mat and a porous collector are successively provided toward outside on the rear face side of the flexible cathode, and to provide a method for manufacturing such a zero-gap electrolytic cell at a low cost. <P>SOLUTION: The zero-gap electrolytic cell having the constitution includes an imperforate plate 10 between the porous collector 7 and the cushion mat 6, the cushion mat 6 is constituted with a metal coil and arranged so that the expansion and contraction direction of the coil coincides with the vertical direction of the electrolytic cell, and in the zero-gap electrolytic cell, gaps are provided respectively in a portion 12 between the imperforate plate 10 and an upper flange of the electrolytic cell; and also in a portion 13 between the imperforate plate 10 and a lower flange of the electrolytic cell. <P>COPYRIGHT: (C)2013,JPO&INPIT |
