Provided are an electrolytic cathode structure that can suppress the degradation of an activated cathode even if a reverse current flows upon the stoppage of operation of an electrolyzer in an electrode structure allowing the distance between the electrode and an electrode current collector to be maintained at an approximately constant value, and an electrolyzer using the same. The electrolytic cathode structure includes a metal elastic cushion membercompressed and accommodated between an activated cathodeand a cathode current collector. At least a surface layer of the cathode current collectorconsumes a larger oxidation current per unit area than the activated cathode. The electrolyzer is partitioned by an ion exchange membrane into an anode chamber for accommodating an anode and a cathode chamber for accommodating a cathode. The electrolytic cathode structure is used for the cathode.

Electrolytic cathode structure and electrolyzer using the same

Provided is a cell for ion exchange membrane electrolysis obtained by improving the performance in electrolysis of an existing bipolar cell for ion exchange membrane electrolysis, in which a cathode partition wall and a rigid cathode being connected together by a plurality of intermediating V-shaped springs, by a simple method. It is a cell for ion exchange membrane electrolysis which is separated by an ion exchange membrane () into an anode chamber () having a rigid anode () and an anode partition wall () and a cathode chamber () having a rigid cathode () and a cathode partition wall (), the rigid cathode () and the cathode partition wall () being connected together by a plurality of intermediating V-shaped springs (). It is a cell for ion exchange membrane electrolysis in which a metal elastic body () and a flexible cathode () are disposed in layers on the surface of the rigid cathode (), the surface being opposite to the surface to which the V-shaped springs () are attached, and a conductive member () is disposed near one end on the opening side of a V-shaped spring (), which conductive member () is electrically connected with the V-shaped spring () when the V-shaped spring () is compressed.
