PURPOSE:To prevent generation of leak current and to prolong the service life of an electrode by holding the liquid level in an electrolytic cell to the level of a discharge part thereof or below and insulating the upper part as a vapor phase part in a bipolar type electrolytic cell of water. CONSTITUTION:An electrolytic cell 4 is constituted by positioning an anode 2 and a cathode 3 to both sides of a porous diaphragm 1 made of 'Teflon(R)' and filling electrolytic liquid therein. A bipolar electrolytic cell of water is formed by connecting this electrolytic cell at several steps in series. When voltage is impressed to this electrolytic cell, current is allowed to flow to the right side from the left side and gaseous oxygen is generated at the anode 2 and gaseous hydrogen is generated at the cathode 3 and both gasses are discharged through the respective manifolds 5, 6 via the discharge parts 7. At this time, both a level transmitter 8 and a level setter 9 are provided to the electrolytic cell and the electrolytic liquid level is held to the end upper than the diaphragm 1 and to the position lower than the level of the discharge parts 7 of the electrolytic cell with a pump 10. Thereby communication of electrolytic liquid in the outlet manifolds 5, 6 is eliminated and generation of leak current is prevented. |
