Abstract

The present invention relates to a porous separator for a redox flow battery and a redox flow battery comprising the same. The porous separator for a redox flow battery comprises: a porous polymer resin membrane; and a coating layer formed on at least one surface of the porous polymer resin membrane and containing at least two kinds of silica having different primary particle diameters and a fluorine resin, wherein the porous separator has air permeability of 4,000 s /100 cc-air or more.
