Abstract[German]
Die Erfindung betrifft einen Redox-Flow-Stack (01). Dieser (01) umfasst ein linkes und ein rechtes Abschlusselement sowie mehrere zwischen diesen Abschlusselementen angeordnete Redox-Flow-Zellen (11). Jede Redox-Flow-Zelle (11) verfügt über eine linke und eine rechte Zellkammer (13, 14) mit entsprechenden Elektroden (17, 18) und Zellrahmen (15, 16) sowie eine Zellmembran (12), die die Zellkammern (13,14) trennt. Zudem sind Zelltrennelemente (19) zwischen benachbarten Zellkammern (13,14) vorhanden. Die Innovation liegt darin, dass alle Zellrahmen (15, 16) aus einem einstückigen, mittels Additive Manufacturing hergestellten Stackrahmen (02) bestehen.[English]
The invention relates to a redox flow stack (01). The stack (01) comprises a left and a right terminating element and a plurality of redox flow cells (11) arranged between these terminating elements. Each redox flow cell (11) has a left and a right cell chamber (13, 14), with corresponding electrodes (17, 18) and cell frames (15, 16), and a cell membrane (12) which separates the cell chambers (13, 14). In addition, there are cell separating elements (19) between adjacent cell chambers (13, 14). The innovation is that all the cell frames (15, 16) consist of a one-piece stack frame (02) produced by means of additive manufacturing.[French]
L'invention concerne un empilement à flux redox (01). Cet empilement (01) comprend un élément de fermeture gauche et un élément de fermeture droit ainsi que plusieurs cellules à flux redox (11) disposées entre ces éléments de fermeture. Chaque cellule à flux redox (11) dispose d'une chambre de cellule gauche et d'une chambre de cellule droite (13, 14) comprenant des électrodes (17, 18) et des cadres de cellules (15, 16) correspondants ainsi qu'une membrane de cellule (12) qui sépare les chambres de cellule (13, 14). En outre, des éléments de séparation de cellules (19) sont présents entre des chambres de cellules (13, 14) adjacentes. L'innovation réside dans le fait que tous les cadres de cellules (15, 16) sont constitués d'un cadre d'empilement (02) monobloc, produit par fabrication additive.
