ABSTRACT:
The present invention is a structural frame particularly suitable for use in an electrochemical cell. The frame comprises an organic plastic member with a plurality of horizontally and vertically spaced-apart shoulders protruding outwardly from opposing generally coplanar anolyte and catholyte surfaces of the plastic member. Each of the shoulders annularly encircles and supports an electrically conductive insert extending from an exterior face of a shoulder on the catholyte surface of the plastic member, through the plastic member, to an exterior face of a shoulder on the anolyte surface of the plastic member.
An electrically conductive substantially completely hydraulically impermeable anolyte cover is matingly affixed to the anolyte surface of the plastic member and adapted to minimize contact between the anolyte and the plastic member. The anolyte cover is resistant to the corrosive effects of the anolyte. An electrically conductive catholyte substantially completely hydraulically impermeable cover is matingly affixed to the catholyte surface of the plastic member and adapted to minimize contact between the catholyte and the plastic member. The catholyte cover is a metal resistant to the corrosive effects of the catholyte.
The invention further includes an electrochemical cell ultilizing a plurality of the above described structural frames removably and sealably positioned in a generally coplanar relationship with each other and with each of the plastic members being spaced apart at least by an anode on one side of the plastic member and a cathode on an opposing side of the plastic member.
