A divided electrochemical cell assembly comprises stacked bipolar substantially square parallel planar electrodes and membranes. The corners and edges of the electrodes with bordering insulative spacers in juxtaposition with the chamber walls define four electrolyte circulation manifolds. Anolyte and catholyte channeling means permit the separate introduction of anolyte and catholyte into two of the manifolds and the withdrawal of anolyte and catholyte separately from at least two other manifolds. The electrodes and membranes are separated from one another by the insulative spacers which are also channeling means disposed to provide electrolyte channels across the interfaces of adjacent electrodes and membranes.

A divided electrochemical cell assembly comprising an essentially cylindrical electrolytic chamber having interior periferal walls, a plurality of stacked bipolar substantially square parallel planar electrodes and membranes so arranged within the chamber that each pair of one electrode and one adjacent membrane defines an electrolyte channel with alternating channels being anolyte channels and alternating channels being catholyte channels and that the corners and edges of the electrodes and membranes in juxtaposition with the interior periferal walls of the chamber define four electrolyte circulating manifolds, means for applying a direct current across the stack of electrodes, means for introducing catholyte at one side of the cylinder and into one of the manifolds, means for withdrawing the catholyte from one other manifold, means for exiting the catholyte at the opposite side of the cylinder from the catholyte introduction, and channeling and insulative spacer means comprising at least two spacers between and along the edges of each catholyte channel; means for introducing anolyte at another side of the cylinder and into another of said manifolds, means for withdrawing anolyte from another manifold, means for exiting anolyte at the opposite side of the cylinder from the anolyte introduction and channeling and insulative spacer means comprising at least two spacers between and along the edges of each anolyte channel.
