PURPOSE:To reduce the current loss owing to a leakage by dividing the laminate cells into small groups, feeding the electrolyte parallel to unit cells in such a small group, and, on the other hand, feeding the electrolyte in series between such small groups. CONSTITUTION:Plural unit cells C1 to C5 are connected in series to compose a small group G1 and the like. In this small group, the electrolyte 3 is fed parallel to each unit cell from a main pipe 4 at the inlet side through a branch pipe 4a, and after the reaction is over, it is collected to a main pipe 6 at the outlet side through a branch pipe 6a, and then fed to the next small group. Between the small groups G1 to G10, the groups are connected in series electrically, and the electrolyte 3 is fed in series. That is, the electrolyte 3 after passing through G1 passes through the small groups G2, G3...G10 in order, and stored in a tank 10. The voltage applied to the electrolyte, therefore, is at the value of two small groups (for ten cells in the figure), and restricted at one-fifths of the value for 50 cells when the electrolyte is fed parallel to the all unit cells. The current loss can be reduced consequently. |
