PROBLEM TO BE SOLVED: To provide a frame body for use in a redox flow cell capable of suppressing temperature rise of electrolyte, while improving heat dissipation of electrolyte in a slit.SOLUTION: A frame body for use in the cell of a redox flow cell includes an opening formed on the inside of the frame body, a manifold through which electrolyte is distributed, and a slit connecting the manifold and opening, and forming a passage of the electrolyte between the manifold and opening. In a cross section orthogonal to the distribution direction of the electrolyte, the slit has a pair of sidewalls facing each other, and has a narrow width portion, where the interval of the sidewalls becomes narrow in the depth direction, at at least a part of the slit in the depth direction.SELECTED DRAWING: Figure 3 |
