Abstract

PURPOSE:To prevent a trouble from affecting other assembled cells when the trouble occurs on part of assembled cells by providing current bypasses between assembled cells connected in parallel electrically. CONSTITUTION:Current bypasses are provided between assembled cells connected in parallel electrically. When one unit cell 31 in an assembled cell A1 is dam aged, the total of the output voltage of five unit cells 41-44 is made smaller than the total of the output voltage of five unit cells 51-55 of an assembled cell B2 due to the reduction of the output voltage of the unit cell 31. The current is partially detoured from the assembled cell A1 to the assembled cell B2 via a current bypass 72 so as to compensate the difference of the output voltage, and the detoured current is returned from the assembled cell B2 to the assembled cell A1 via a current bypass 71. The imbalance of the cell density between the assembled cell A1 and the assembled cell B2 is not affected to the whole and can be limited to the minimum.
