Abstract

La présente invention concerne un dispositif de désionisation capacitif. Selon le dispositif de désionisation capacitif, un fluide peut être rendu mobile à l'aide d'une paire d'éléments de support, et une partie d'espace dans laquelle se trouve un module d'électrode peut être fournie pour simplifier le procédé de fabrication. En outre, le module d'électrode peut être disposé dans la direction de la longueur d'un boîtier, et une pluralité d'électrodes peuvent être empilées en parallèle dans la direction de la hauteur de manière à ce que les composants de terminaux de raccordement soient disposés sur les deux extrémités de la partie d'espace pour minimiser l'espace requis pour le raccordement des terminaux, miniaturisant ainsi le dispositif de désionisation capacitif.
