It is set not to fall below. This is because if the interface 10 exceeds the upper surface of the buffer tank 7, the electrolytic solution may overflow and cause a short circuit between the single cells. Conversely, if the interface 10 is below the upper surface of the power generating element 2, the power generating element is contaminated with the insulating solution. This is because it causes deterioration of battery performance. The cell tank 1 and the buffer tank 7 are in communication with each other,
Since it can be regarded as substantially the same space, the interface 10 in the buffer tank 7 is also regarded as “the interface in the unit cell”.

The water adsorbent may be placed in the internal space of the battery storage tank partitioned by a pressure equalizer described later, but by filling the buffer tank tank 7, the water can be more efficiently and reliably used for organic electrolysis. It is possible to prevent the liquid cell from invading. Of course, it is more effective to fill both the inside of the buffer tank 7 and the inside of the battery storage tank.
