覆されている（例えば特公昭47−38753号公報）。 Conventionally, diaphragm electrolyzers for salt water electrolysis are
An electrolytic cell is used in which metal anodes and diaphragm-coated cathodes are arranged vertically to the bottom plate of the electrolytic cell, with the metal anodes and diaphragm-covered cathodes facing each other alternately. The rubber sheet is coated with a rubber sheet such as chloroprene to protect it from the electrolyte (for example, Japanese Patent Publication No. 47-38753).

る。 FIG. 1 is a partial vertical sectional view of an electrolytic cell in which an anode is attached to the bottom plate of the electrolytic cell according to an embodiment of the present invention. The diaphragm-coated cathode is omitted. In the figure,
1 is the bottom plate of the electrolytic cell according to the present invention. The bottom plate 1
The rubber sheet 3 made of chloroprene is provided on a conductive base 2 made of copper or aluminum, and the surface of the rubber sheet 3 is further covered with a sheet 4 of polytetrafluoroethylene. The bottom plate 1 has a hole through which a conductive rod 5 is inserted.
and an anode active surface 6 are attached.

せ材を用いることもできる。 The conductive substrate and rubber sheet of the bottom plate of the electrolytic cell according to the present invention may be the same as those used in conventional diaphragm type electrolytic cells. The fluororesin sheet has a thickness of about 0.2 to 1 m/m and covers the entire surface of the rubber sheet. Furthermore, a composite material of a rubber sheet and a fluororesin sheet can also be used.
本考案に係る電解槽の底板は、表面層のフツ素
樹脂のシートが電解液に対する耐食性に優れてい
るため、導電性の基盤とゴムシートから成る従来
の底板に比較して３倍程度寿命が長い。 The bottom plate of the electrolytic cell according to the present invention has a surface layer of fluororesin sheet that has excellent corrosion resistance against electrolyte, so it has a lifespan approximately three times longer than that of a conventional bottom plate made of a conductive base and a rubber sheet. long.
また、本考案は、ゴムシートに代えてフツ素樹
脂のみによつて導電性の基盤の被覆層を構成した
場合に比較して安価である。 Furthermore, the present invention is less expensive than the case where the coating layer of the conductive base is constructed of only fluorine resin instead of the rubber sheet.
