Frame body, cell frame for redox flow battery, and redox flow battery

摘要

There is provided a frame body used for a cell of a redox flow battery, that can improve heat dissipation of an electrolyte in a slit while reducing a shunt current loss 5 through the electrolyte, and can also suppress strain caused at a slit formation portion. It is a frame body used for a cell of a redox flow battery, comprising: an opening formed inside the frame body; a manifold allowing an electrolyte to pass therethrough; and a slit which connects the manifold and the opening and forms a channel of the electrolyte between the manifold and the opening, the slit having at least one bent 10 portion, the at least one bent portion having a radius of curvature of 2.0 mm or more and 200 mm or less. - 34 -
