Abstract
Provided is a redox flow battery in which damage is unlikely to occur in a membrane. A redox flow battery includes a pair of adjacent cell frames, each cell frame including a frame body in which a flow channel for an electrolyte is formed, and a bipolar plate disposed inside the frame body; a positive electrode and a negative electrode disposed so as to face each other between the bipolar plates of the pair of cell frames; a membrane interposed between the positive electrode and the negative electrode; a protection plate which covers the flow channel and presses edge portions of the positive electrode or the negative electrode toward the bipolar plate; and a membrane protection structure which prevents the membrane from being broken by contact between the protection plate and the membrane.
