Title (EN) NOVEL MODULAR ELECTROCHEMICAL CELL AND STACK DESIGN
(FR) NOUVELLE CELLULE ÉLECTROCHIMIQUE MODULAIRE ET CONCEPTION D'EMPILEMENT
Abstract:
(EN) 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.
(FR) La présente invention concerne une cellule électrochimique, un ensemble de cellules électrochimiques et un procédé d'assemblage d'un ensemble de cellules électrochimiques. La cellule comprend une paire de collecteurs de courant qui, quand ils sont assemblés, forment un ensemble électrode tridimensionnelle avec une membrane échangeuse d'ions disposée entre l'anode et la cathode de l'ensemble électrode. Les dimensions et la forme des collecteurs de courant sont telles qu'un volume tridimensionnel de chambre pour réactif de l'un des collecteurs de courant accepte un placement imbriqué d'au moins une partie du volume tridimensionnel de chambre pour réactif de l'autre collecteur de courant. Cette conception permet d'ajouter, de retirer ou de remplacer facilement et directement des cellules dans une empilement de cellules de ce type de manière modulaire. De plus, la facilité de montage et de démontage des cellules sur des distributeurs de réactifs facilite l'assemblage de structures d'empilement bidimensionnelles ou tridimensionnelles.
