Abstract: A flow frame for a redox flow battery includes: a frame body having a plate-like shape and an electrode hole in its center where an electrode is to be disposed; four through holes disposed at corners of the frame body, respectively; a flow channel disposed at a front of the frame body above and below the electrode hole so that two of the through channels diagonal to each other as a pair are connected to each other via the electrode hole; through channels disposed at distal ends of the flow channel to cause electrolyte flows toward a rear of the frame body; and a distribution channel connecting the through channels with the electrode hole at the rear of the frame body. The flow channel has at least one branch point, and a change in cross sectional area of the flow channel before and after the branch point is 10% or less.
