Zero-gap electrolyzer, and a manufacturing method thereof

An anode, an ion exchange membrane, and a flexible cathode are arranged in close contact with each other, and a cushion mat and a porous current collector are sequentially provided on the back side of the flexible cathode. In the zero gap electrolytic cell, the interface concentration between the flexible cathode and the ion exchange membrane can be kept uniform and appropriate. Moreover, the method of manufacturing such a zero gap electrolytic cell at low cost is provided. A zero-gap electrolytic cell having the above-described configuration, which includes a non-perforated plate 10 between a porous current collector 7 and a cushion mat 6, and the cushion mat 6 is formed of a metal coil body. The coil body is disposed so that the expansion / contraction direction of the coil body coincides with the vertical direction of the electrolytic cell, and 12 between the non-perforated plate 10 and the upper flange of the electrolytic cell, and the non-perforated plate and the lower flange of the electrolytic cell. Zero gap electrolyzers each having a gap between 13 and. [Selection] Figure 4
