FLOW BATTERY WITH ROTATIONALLY SYMMETRIC MANIFOLD PLATES

摘要

A flow battery includes a stack of manifold plates that define first and second exclusive flow circuits through the stack between first and second stack inlets and first and second stack outlets. The manifold plates each include a frame that extends around a flow field of an electrochemically active area, with a plurality of port through-holes in the frame. The through-holes are arranged in a rotationally symmetric pattern about a center of the respective manifold plate.
