A structural frame adapted for use in a solid polymer electrochemical cell, which comprises a generally planar organic plastic member having a plurality of horizontally and vertically spaced-apart shoulders protruding outwardly from opposing generally coplanar anolyte and catholyte surfaces of the plastic member. Electrically conductive, hydraulically impermeable, anolyte and catholyte corrosion resistant covers are matingly affixed to the respective surfaces of the plastic member. A hydraulically permeable, electrically conductive, current collector is contacting and positioned adjacent the catholyte cover. An ion exchange membrane, having an electrically conductive, electrocatalytic material bonded to or embedded in the surface of the membrane is positioned adjacent and in contact with the current collector. The frames are removably and sealably positioned in coplanar relationship, each plastic member being spaced apart by an anode on one side and a cathode on the other.

A structural frame adapted for use in an electrolytic cell comprising: an organic plastic member with a plurality of horizontally and vertically spaced-apart shoulders protruding outwardly from opposing generally coplanar first and second surfaces of said plastic member; at least one electrically conductive insert extending from an exterior face of a shoulder on the first surface of the plastic member, through the plastic member, to an exterior face of a shoulder on the second surface of the plastic member, wherein each of said shoulders annularly encircle and support said insert; an electrically conductive, substantially completely hydraulically impermeable second cover resistant to the corrosive effects of electrolyte matingly contacted with the second surface of said plastic member and adapted to minimize contact between the electrolyte and said plastic member within the cell; an electrically conductive, substantially completely hydraulically impermeable first cover resistant to the corrosive effects of electrolyte matingly contacted with the first surface of said plastic member and adapted to minimize contact between the electrolyte and said plastic member within the cell; a hydraulically permeable, electrically conductive, current collector adjacent to and contacting the first cover; an ion exchange membrane adjacent to and contacting the current collector; and an electrically conductive, electrocatalytic material bonded to or embedded in the surface of the ion exchange membrane contacting the current collector. An electrolytic cell comprising: a plurality of the structural frames of claim 1 removably and sealably positioned in a generally coplanar relationship with each other and each of said plastic members being spaced apart by a second electrode on one side of each of said frames and a first electrode on an opposing side of each of said frames.
