ABSTRACT:
A particular side frame design for use in an electrochemical cell with a catholyte flow pattern is disclosed wherein the cell can be generally horizontal or angled slightly from the horizontal and the catholyte is fed through a transition area into a gap in the catholyte compartment between the liquid metal cathode and the membrane on a first end and exits the gap on an opposing second outlet end. The side frame has opposing sides that are obliquely and downwardly angled in the corners to support the membrane in a wrinkle free manner so that the membrane is obliquely positioned between the liquid metal cathode and the anode. The membrane is above the level of the catholyte where the catholyte enters and exits the catholyte compartment, but drops to a level below the entry and exit points.
