Zusammenfassung:There is disclosed a cell sealing mean particularly for a chlor-alkali diaphragm cell. The sealing means will usually be contained along a rim portion at the outer edge of an electrode assembly of the diaphragm cell. The sealing means comprises a pneumatic gasket system. In one embodiment, the system can have an outer gasket member comprising a solid and thick, elongated elastomeric strip element. The strip element will generally have front and back major faces, with the front face containing a channel, and with a side face typically having a flange. Combined with the outer gasket member in this embodiment is an inner gasket member that is a thin, elongated elastomeric strip member. It has an inflatable hollow and flexible tube element forming at least a portion of the inner gasket member. It is desirable that the element be a laminate of differing laminate materials. As a second embodiment, the sealing means comprises a gasket member of a thick, elongated strip element having a major cavity extending in the length dimension of the element. A stem connector, for providing and regulating fluid flow, can be provided with the tube element of the first embodiment or the cavity of the second embodiment.
