Abstract
An electrochemical cell, electrochemical cell assembly and a method of assembling an electrochemical cell assembly. The cell includes a pair of current collectors that when joined together form a three-dimensional electrode assembly with an ion-exchange membrane disposed between the anode and cathode of the electrode assembly. The current collectors are sized and shaped such that a three-dimensional reactant chamber volume of one of the current collectors accepts nested placement of at least a portion of the three-dimensional reactant chamber volume of the other current collector. This design allows for easy and direct addition, removal or replacement of cells in a stack of such cells in a modular fashion. In addition, ease of mounting and unmounting of the cells on reactant manifolds promotes ease of assembly of two-dimensional or three-dimensional stack structures.
