HIPO STACK: High Power Redox Flow Stacks

The costs for redox flow batteries are to be reduced so that a new product is created by significantly improving the stack in terms of power density and costs. For this purpose, suitable flow fields are to be developed, which are then integrated into the plates via a new punching or embossing process for compound bipolar plates. As an optimal supplement to this, a novel nano-structured membrane is to be developed which has a greater proton permeability than the classic ion-selective membranes and can be produced much more cost-effectively. The new membrane is coated to achieve a constant selectivity. Due to the possibly greater permeability of this membrane for vanadium ions and water, it can only be used sensibly if the pressure conditions in the cell can be controlled by means of optimized flow fields. This shows the close relationship between the individual components in the stack and the need to optimally match them to each other. Thus, the goal of a small-volume redox flow stack with high power density can be achieved and an important contribution to the market maturity of redox flow technology can be made.
