PURPOSE:To make airtightness ever so better as well as to facilitate setting operations for a manifold, by interposing a metallic frame, where rubber molding packing having electric insulation and acid resistance at each side is set up, between the manifold and a cell body. CONSTITUTION:At the cell body side of a metallic frame 8, rubber molding packing 5 consisting in size and form of the same degree as this metallic frame 8 and having electric insulation and acid resistance is adherently set up there. At the side of a manifold 4, rubber molding packing 9 having the electric insulation and acid resistance is housed and set up in a groove 10 installed in the manifold side. An uneven surface at the cell body side is coated with a fluorocarbon system seal material 6, filling up a concave part, and after this seal material is sealed with the metallic frame 8 setting up the packing 5, the seal material 6 is applied to the concave part for filling up. A seal between the metallic frame 8 and the manifold 4 comes to such a seal structure as excellent in reliability enough only the molding packing 9 is interposed in between and clamped tight. |
