<p>A multicompartmented cell suitable for use as electrochemical and chemical reactor cells is formed with a freely-extendible tubular membrane (4,5) which is a thin-walled, preferably ion selective permeable, membrane sleeve which from a dry condition tends to expand and lengthen upon hydration. An end plug (6,7) fastened at one end of the membrane provides fluids closure whereby the closed membrane end with its end closure is free to move, i.e., is unattached. A cell head (10) to which the other end of the membrane is connected, together with the membrane and the end plug (6,7) define a compartment (1,2,3). The cell heat (10) is provided with means for ingress and egress of fluids to and from such compartment (1,2,3) and can also be provided with electrical access to an appropriate electrode (8,9). External to the membrane sleeve is a suitable containing means spaced from the membrane to form a compartment outside the membrane, the containing means being sufficient in size to accommodate the membrane in expanded and lengthened condition. This second compartment can contain, for electrochemical process use, an appropriately spaced electrode (8,9). This means for making cells is especially applicable for cells compartmented with perfluorinated membranes that undergo large dimensional changes on hydration and drying.</p> |
