PURPOSE:To perform stabilized electrolysis even at a high current density in the cell for electrolyzing an aq. soln. of alkali metal chlorides by providing a device for uniformly distributing an electrolyte to the anode and cathode chambers. CONSTITUTION:The pan-shaped bodies 2 for the anode and cathode chambers consisting of the hooked flange, peripheral wall and side wall and to which the anode and cathode are stuck through a conductor rib 3 extending into the space formed by the latter two are arranged back-to-back. A rod-shaped frame is inserted into the space formed by the flange and peripheral wall to constitute the anode and cathode chambers. Many units thus obtained are arranged through a cation-exchange membrane to constitute the electrolytic cell. A gas-liq. separation chamber is furnished at each nonconductive part over the anode and cathode chambers, and a device 17 for uniformly distributing the supplied electrolyte to the anode and/or cathode chambers is provided. Consequently, the circulation of electrolyte is sufficiently secured even if the electrolytic cell is pressurized or depressurized, the cell is not vibrated even at a high current density and with a concd. alkali, and electrolysis is stably performed. |
