PURPOSE:To efficiently replenish an electrolyte and to make a replenishing system compact by installing an electrolyte storage chamber in the upper end plate of a stacked cell and installing an electrolyte replenishing passage to each cell which is passing through the storage chamber and a passage for compressing the electrolyte from the outside. CONSTITUTION:When an electrolyte within an electrolyte plate 4 is exhausted, an electrolyte 13 in a storage chamber in an upper end plate 2 is replenished to each electrolyte plate 4 through a replenishing hole 8 by gas pressure from a gas passage 11. The electrolyte is in a molten state, and is redy to replenish without specific heating. The electrolyte flows down to the end of a separator 5A, and flows along a replenishing groove 14 like an arrow 16. The electrolyte flows down to a lower electrolyte plate and a separator 5B from a replenishing hole 9 of the separator 5A. A replenishing hole 9 of the separator 5B is installed in the different position from the separator 5A, and the electrolyte flows along a replenishing hole of the separator 5B. A sufficient electrolyte is replenished to the electrolyte plate in each unit cell in such a way. |
