Abstract
The unique cell frame of the present invention comprises an integral protector portion. This protector portion comprises a rigid or flexible lip on the membrane side of the cell frame. In an assembled cell stack, the membrane assembly is disposed between two cell frames on the side of the cell frames having the protector portion. Screen assemblies are disposed on the opposite side of the cell frame such that the screen assemblies rest on the protector portion, within the cell frame. The protector portion prevents the edge of the screen assemblies from pinching, cutting, or otherwise damaging the membrane.
