Structure-integrated electrochemical cell and structure-integrated stack constructed therefrom

Abstract

An electrochemical cell, more particularly a redox flow battery, and to a stack having a cell assembly composed of two or more electrochemical cells of this type. The cell includes at least one cell frame and at least one electrode, wherein the cell frame peripherally surrounds a cell interior, and wherein the cell frame has at least one supply channel for supplying a fluid into the cell interior and at least one discharge channel for discharging the fluid from the cell interior, and optionally at least one semipermeable membrane and optionally at least one bipolar plate. The cell frame, the electrode, the optional semipermeable membrane and the optional bipolar plate are substantially connected in a form-fitting manner to each other, more particularly substantially connected in a form-fitting manner to each other in the region of the active cell area. A cell of this type is particularly suitable for applications in aviation, shipping and space travel.
