    Abstract: The problem addressed by the present invention is to obtain an electrolyte membrane that, as an electrolyte membrane for a redox flow secondary battery, is able to suppress the ion permeability of an active substance without detracting from proton (H+) permeability, has superior ion-selective permeability, has low electrical resistivity, and has superior current efficiency. The present invention solves the abovementioned problem by means of the electrolyte membrane for a redox flow secondary battery containing a perfluorocarbon sulfonic acid resin having a specific structure and an equivalent weight (EW), and the ion conductivity being adjusted to a predetermined range.

    Abstract: This redox flow secondary battery has an electrolyte tank (6) containing: a positive electrode cell chamber (2) containing a positive electrode (1) comprising a carbon electrode; a negative electrode cell chamber (4) containing a negative electrode (3) comprising a carbon electrode; and an electrolyte membrane (5) as a barrier membrane that separates/isolates the positive electrode cell chamber (2) and the negative electrode cell chamber (4). The positive electrode cell chamber (2) contains a positive electrode electrolyte containing an active substance, the negative electrode cell chamber (4) contains a negative electrode electrolyte containing an active substance, and the redox flow secondary battery charges and discharges on the basis of the change in valency of the active substances in the electrolytes. The electrolyte membrane (5) contains an ion exchange resin composition that is primarily a polyelectrolyte polymer, and the electrolyte membrane (5) has a reinforcing material comprising a fluorine-based porous membrane.
