PROBLEM TO BE SOLVED: To provide an electrolyte circulation type battery which enables the suppression of deformation of frame bodies of cell frames.SOLUTION: An electrolyte circulation type battery comprises: dipole plates in contact with electrodes for forming battery cells; and cell frames having frame bodies surrounding peripheral edges of the dipole plates. The frame bodies each have: a supply-side piece with a supply-side manifold for supplying an electrolyte into a corresponding battery cell; and an exhaust-side piece with an exhaust-side manifold for exhausting the electrolyte to outside the battery cell, which is opposed to the supply-side piece. Each dipole plate has, in its electrode side face, a circulating area through which the electrolyte supplied from the supply-side manifold is circulated and then exhausted to the exhaust-side manifold. The circulating area has: a liquid-supply rectifying part provided along a vertical direction, diffusing the electrolyte supplied from the supply-side manifold in the vertical direction, and leading the electrolyte to the electrode; and exhaust-liquid rectifying parts provided laterally on both sides of the liquid-supply rectifying part so as to extend along the vertical direction, and serving to intensively circulate the electrolyte to the exhaust-side manifold.SELECTED DRAWING: Figure 1 |
