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 an- 24A 26A ode and cathode of the electrode assembly. The current collectors are sized and io /20 22 / 26 shaped such that a three-dimensional reactant chamber volume of one of the li 0 f I r. 1 current collectors accepts nested placement of at least a portion of the three- dimensional reactant chamber volume of the other current collector. This de- sign allows for easy and direct addition, removal or replacement of cells in a Illit / mounting of the cells on reactant manifolds promotes ease of assembly of two- dimensional or three-dimensional stack structures. stack of such cells in a modular fashion. In addition, ease of mounting and un- ,MMI // FIG. 1 [Continued on next page] WO 2018/160317 Al OII TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
