PURPOSE:To improve the storage performance of a laminated cell along with the prevention of fluid leakage thereform by electrically connecting the collecting plates of adjoining positive and negative electrodes of a power generating element to each other via a film provided with a transmissible hole and covering a group of stacked power generating elements with a common housing. CONSTITUTION:A film 28 not penetratable for electrolyte is interposed between a negative electrode collecting plate 26a or 26b and a positive electrode collecting plate 24b or 24c in a part between power generating elements 10a, 10b and between 10b, 10c stacked via a separator 18. A transmissible hole 28a is formed in the center of said film 28, and the surfaces of the respective collecting plates 26a, 24b and 26b, 26c facing to and being in contact with each other are subjected to spot welding 30 to electrically and mechanically couple them. The peripheral edge of each film 28 is simultaneously sealed in its sandwitched state when thermal sealing 16 the housing 14. With use of thus structured laminated cell, the respective power generating elements 10a, 10b, and 10c are individually separated to permit an electric contact state among them to be improved. |
