Abstract
Various embodiments of redox flow battery stack assemblies may include a plurality of multiple-block strings, where each string may include a plurality of reaction blocks connected in electrical series and in fluidic parallel. Various embodiments provide configurations and systems for mitigating or substantially reducing shunt currents in common electrolyte conduits.
Claims6
A redox flow battery stack assembly comprising:
- an electrolyte inlet conduit and an electrolyte outlet conduit;
- a plurality of flow battery cell blocks fluidically connected in parallel with one another between the inlet conduit and the outlet conduit;
- wherein the cell blocks are arranged into groups, each group having a plurality of cell blocks configured to operate across a common voltage range, and wherein the groups are joined to the electrolyte inlet conduit and the electrolyte outlet conduit such that shunt currents may only flow in the inlet conduit or the outlet conduit between adjacent groups.
