Abstract
A redox flow battery includes an electrode, a cell frame including a frame body and a bipolar plate and having a fitting recess in which the electrode is fitted, and a membrane disposed so as to sandwich the electrode between the bipolar plate and the membrane. In the redox flow battery, a gap between, among outer peripheral edge surfaces of the electrode, a side edge surface parallel to a direction in which an electrolyte flows and an inner wall surface of the fitting recess, the inner wall surface facing the side edge surface, is 0.1 mm or more and 12 mm or less.
