Abstract
This invention provides a cell frame for a redox flow battery that prevents leakage of electrolyte out of the cell frame and also provides a good workability in assembling the redox flow battery. Also, this invention provides a redox flow battery using the cell frame. In the cell framefor the redox flow batterycomprising a bipolar plateand a framefitted around a periphery of the bipolar plate, the framehas, on each side thereof, an inner seal and an outer seal to press-contact with a membrane and also seal electrolyte. The framehas, on each side thereof, an inner seal grooveand an outer seal groovefor placing therein the inner seal and the outer seal, respectively, to prevent the electrolyte from leaking out, and O-rings are placed in the respective seal grooves.
