Abstract
A unitary frame and membrane assembly particularly useful in a filter press electrolytic cell arrangement is provided by the present invention. The assembly comprises a rigid, peripheral frame member having separable peripheral frame portions. A permselective membrane member is positioned between the separable peripheral frame portions, and the membrane member and frame portions are secured together to form a unitary frame and membrane assembly. The present assembly is adapted for use as the barrier component in electrolytic cells which utilize a separatory membrane barrier between the cell electrodes.
