There is disclosed a cell sealing means particularly for a chlor-alkali diaphragm cell (10). The sealing means will usually be contained along a rim portion at the outer edge of an electrode assembly of the diaphragm cell (10). The sealing means comprises a pneumatic gasket system (90). In one embodiment, the system (90) can have an outer gasket member (40) comprising a solid and thick, elongated elastomeric strip element (40). The strip element will generally have front (42) and back (41) major faces, with the front face containing a channel, and with a side face typically having a flange (16). Combined with the outer gasket member in this embodiment is an inner gasket member (80) that is a thin, elongated elastomeric strip member (40). It has an inflatable hollow and flexible tube element (81) forming at least a portion of the inner gasket member (80). It is desirable that the element (81) be a laminate of differing laminate materials. As a second embodiment, the sealing means (110) comprises a gasket member of a thick, elongated strip element having a major cavity (117) extending in the length dimension of the element. A stem connector, for providing and regulating fluid flow, can be provided with the tube element (81) of the first embodiment or the cavity (117) of the second embodiment. |
