PURPOSE:To prevent exhaustion of electrolytic solution by closing an air hole of a cell with a sealing member having a convex part and made of synthetic resin. CONSTITUTION:Air (oxygen) is taken-in from an air hole 2 formed on a cell case 1, and said air is ionized by catalyst 6, and a cell system is constituted with zinc acting as negative electrode 11 through a separator 7. In preservation, a sealing member 3 for closing the air hole 2 is used. As said sealing member 3 is equipped with a convex part 2a on its one side at the position opposite to the air hole 2, liability of falling-off is prevented, and mounting onto equipment is simplified. |
