Electrochemical cell stack assembly

Abstract

Multiple stacks of tubular electrochemical cells having a dense electrolyte disposed between an anode and a cathode preferably deposited as thin films arranged in parallel on stamped conductive interconnect sheets or ferrules. The stack allows one or more electrochemical cell to malfunction without disabling the entire stack. Stack efficiency is enhanced through simplified gas manifolding, gas recycling, reduced operating temperature and improved heat distribution.

         86 . An electrochemical cell stack assembly, comprising:
 a plurality of conductive interconnect plates;   each said interconnect plate having a plurality of apertures; and   a plurality of tubular electrochemical cells disposed and sealed between said interconnect plates;   wherein a said tubular electrochemical cell is oriented over a corresponding said aperture to form a gas passageway.   
     
     
         87 . A module for a modular assembly of electrochemical cells, comprising:
 a first set of tubular electrochemical cells, each said cell having an anode contact end and a cathode contact end;   a second set of tubular electrochemical cells, each said cell having an anode contact end and a cathode contact end; and   an electrically conductive interconnect sheet with a plurality of apertures and top and bottom sides, said top side of said interconnect sheet configured to electrically couple with said anode contact ends of said first set of electrochemical cells, said bottom side of said interconnect sheet configured to electrically couple with said cathode contact ends of said second set of electrochemical cells;   wherein said first and second set of electrochemical cells are aligned over the apertures of the interconnect sheet forming gas passageways through said electrochemical cells and said interconnect sheet.
