PROBLEM TO BE SOLVED To improve product yield by preventing deterioration of battery performance. Bipolar electrodes 270 having a positive electrode layer formed on one surface of the current collector and a negative electrode layer formed on the other surface, and electrolyte layers 230 that exchange ions between the bipolar electrodes are alternately arranged. A battery element 210 formed by laminating a predetermined number of the battery elements, and a stack thickness absorbing member 260 that is interposed between the battery elements and absorbs strain in the stacking direction, and a plurality of batteries are interposed via the stack thickness absorbing member. The power generation elements 160 are formed by alternately stacking the elements 210. [Selection] Figure 2 |
