PROBLEM TO BE SOLVED: To simply connect between unit cells and strongly keep the connection between unit cells by connecting outer terminals of positive and negative electrodes with a screw. SOLUTION: Outer terminal scan be connected in various forms. In a unit cell 31, an outer terminal 41 for a positive electrode formed in a male screw shape and an outer terminal 42 for a negative electrode formed in a female screw shape are separately installed at the both ends of the unit cell 31. Series connection of the unit cells 31 is simply and strongly performed, and contact resistance in the connected part can be reduced. In a unit cell 32, an outer terminal 43 for a positive electrode and an outer terminal 44 for a negative electrode are both formed in a male screw shape. A bolt 51 is connected to one outer terminal, then the other outer terminal is fit to the bolt 51 to make simple connection possible. In a unit cell 33, an outer terminal 45 for positive electrode and an outer terminal 46 for a negative electrode are both formed in a female screw shape. In this case, a rod-shaped screw 52 is used and similar connection is made possible. |
