PROBLEM TO BE SOLVED: To provide an electrolyte circulation type battery superior in productivity, which allows a seal structure of an electrolyte to be constructed readily.SOLUTION: An electrolyte circulation type battery comprises: dipole plates in contact with electrodes for forming a battery cell; cell frames having frame bodies surrounding peripheral edges of the dipole plates; and seal members for preventing an electrolyte supplied to the battery cell from being leaked to the outside the frame bodies, which are disposed on the corresponding frame bodies. The frame bodies have seal grooves in which the corresponding seal members are fit in. The seal grooves have narrow-width parts serving to elastically deform the seal members, thereby preventing the seal members from falling from the seal grooves. The narrow-width parts are each uniform in width along a depth direction of the corresponding seal groove.SELECTED DRAWING: Figure 1 |
