Abstract
A redox flow battery includes: a membrane; and electrodes that are disposed in a compressed state on both sides of the membrane and sandwich the membrane. The thickness x (μm) of the membrane and the compression ratio y (%) of the electrodes satisfy the following relation A or B: (A) when the electrodes are formed from carbon felt, y<x+60, 30≤y≤85, and 5≤x≤60 hold; (B) when the electrodes are formed from carbon cloth or carbon paper, y<1.2x+42, 10≤y≤85, and 5≤x≤60 hold, where y={1−(the thickness during compression/the thickness before compression)}×100.
