FRAME FOR UNIFORMLY SUPPLYING ELECTROLYTE TO IMPROVE CELL-EFFICIENCY AND REDOX FLOW BATTERY HAVING THE FRAME

摘要

Disclosed is a frame for a redox flow battery. The present invention aims to provide the frame, which includes a flow channel, uniformly provides electrolyte to the inside of a cell, and thus can increase efficiency of the cell. The frame includes a frame body, a first manifold, an inlet flow path, an inlet channel, and an outlet flow channel. A frame body includes an opening for a chamber formed on the center thereof. The first manifold is formed to penetrate the frame body. The inlet flow path is connected with the first manifold and is extended in a first direction. The inlet channel connects the inlet flow path and the opening for the chamber, and is formed by a plurality of channel separation walls arranged in a row along an upper edge of the opening for the chamber. Corner parts of the channel separation walls contacting the inlet flow path are formed to be curved. A radius of curvature of the corner part increases as the distance from the first manifold increases. A second manifold is formed on a location placed apart from the first manifold. The opening for the chamber is interposed between the first manifold and the second manifold. The outlet flow path connects the second manifold and the opening for the chamber.
