The present invention relates to a cell for analyzing the characteristics of a felt electrode used for analyzing characteristics of a felt electrode used in a redox flow battery. The cell includes an electrolyte chamber in which a space filled with an electrolyte is formed, A reference electrode section having a reference electrode; a working electrode which is disposed on one side of the reference electrode section as a reference and which is a felt electrode to be analyzed; and a response from the working electrode in a state in which the pressure applied to the working electrode is kept constant. And a counter electrode portion disposed on the opposite side of the working electrode portion with respect to the reference electrode portion for maintaining a balance of charge as electrons are transferred from the working electrode portion to the counter electrode portion, The electrical characteristics can be analyzed accurately.
