Abstract

See full text

A redox flow battery includes a cell stack formed by stacking a plurality of battery cells, a positive electrolyte circulation mechanism configured to circulate a positive electrolyte in the cell stack, and a negative electrolyte circulation mechanism configure l to circulate a negative electrolyte in the cell stack. The redox flow battery includes a pressure difference forming mechanism that makes one of a pressure loss in a positive pipeline included in the positive electrolyte circulation mechanism and a pressure loss in a negative pipeline included in the negative electrolyte circulation mechanism greater than the other so that, when the positive electrolyte and the negative electrolyte are circulated in the cell stack, a pressure difference state is created where there is a difference between the pressures of the positive and negative electrolytes acting on a separation membrane included in each battery cell.
