Abstract

A redox flow battery comprising an redox flow stack comprising a plurality of flow frames arranged face-to-face in said stack, each frame having a support border surrounding a central opening, each frame having a first and a second face, and each frame comprising: a bipolar plate fitted in said central opening providing a fluid-tight seal and defining two chambers on each face of said bipolar plate; two porous electrodes, each respectively contained in one of said chambers; an ion-selective membrane for interfacing with the next frame in said stack; and openings for posilyte and negolyte flow respectively through one of said electrodes; wherein each said face of the support border has a first border region and a second border region arranged in opposite ends in respect of said central opening, each said border region comprising meandering channels for posilyte or negolyte flow through a respective frame chamber.
