Title:

COLLECTOR PLATE UNIT AND REDOX FLOW BATTERY

Document Type and Number:

WIPO Patent Application WO/2020/138049

Kind Code:

A1

Abstract:

This collector plate unit comprises an electrode that is arranged between an ion exchange membrane and a collector plate, and a cell frame which surrounds the outer peripheral surfaces of the collector plate and the electrode; and this collector plate unit is used in a redox flow battery. A collector plate unit (200) according to the present invention is obtained by integrating a collector plate (20) and a cell frame (40) with each other; the collector plate comprises a flow path that is composed of a groove which is formed in a concave shape in a surface facing the electrode, and a collector plate supply pipe that penetrates through the collector plate so as to supply an electrolyte solution to the flow path; the collector plate supply pipe has a collector plate inlet which opens to the outer peripheral surface that faces the cell frame; a surface of the cell frame facing the collector plate inlet is provided with a frame opening through which the electrolyte solution is supplied to the collector plate inlet; and the collector plate inlet (21i) and the frame opening (53a) are bonded to each other, with a sealing member (51) being interposed therebetween.
