Cell and Cell Stack of a Redox Flow Battery

摘要

Provided herein is a cell of a redox flow battery, having at least one cell frame element, a membrane and two electrodes. The at least one cell frame element, the membrane and the two electrodes surround two cell inner spaces which are separate from each other. In the at least one cell frame element, at least four separate channels are provided in such a manner that different electrolyte solutions can flow through the two cell inner spaces. With the exception of the at least four separate channels, the cell is constructed in a fluid-tight manner. At least the at least one cell frame element is welded to the membrane, the two electrodes, and/or at least one additional cell frame element to provide the redox flow battery with a higher power of density.
