However, in the case of the deep-sea organic electrolyte battery disclosed herein, the power generation element and the electrolytic solution are housed in the unit cell tank to maintain the pressure balance in the pressure equalizer. There is a problem that a pressure equalizing device is required for each unit cell because the structure is maintained by moving and contracting the liquid.
(When a plurality of cells are housed, it becomes a common electrolyte and causes a problem of current leakage between the cells.) Further, what is important in the organic electrolyte battery is how to eliminate the adverse effect of water. Not to mention the case of the conventional aqueous electrolyte battery shown in FIG. 1,
Even in the case of the deep-sea organic electrolyte battery, no consideration is given to measures against water entering through the pressure equalizer. Therefore, the expected performance is not always obtained.
