Konzipierung eines High Power Redox Flow Stacks
The main fields of application for energy storage systems are the shifting of excess renewable energies to times of increased demand and the capping of power peaks to reduce grid connection fees. In the field of stationary energy storage, redox flow batteries and in particular vanadium redox flow batteries (VRFB) are currently proving to be very promising. In order to be able to use this type of energy storage system decentrally for SMEs or apartment buildings, the power density must be significantly increased compared to the current state of the art. This is the aim of the cooperation project between the companies Eisenhuth, Volterion, TU Braunschweig and Clausthal University of Technology. Among other things, the field of activity of TU Clausthal is to develop a suitable flow field for use in the new high-performance cell. Using flow fields, the pressure loss during the transport of the electrolyte can be significantly reduced while maintaining cell performance. The project also aims to test new concepts in the field of bipolar plates and cell membranes and thus develop a new, high-performance cell concept.
