CELL FRAME, CELL STACK, AND REDOX FLOW CELL

摘要

PROBLEM TO BE SOLVED: To provide a cell frame capable of adjusting the difference between the pressure of a positive electrode electrolyte and the pressure of a negative electrode electrolyte, which act upon components in a cell.

SOLUTION: A frame body 122 provided in a cell frame 1 has: a positive electrode electrolyte channel 8A serving as a channel for a positive electrode electrolyte; and a negative electrode electrolyte channel 9A serving as a channel for a negative electrode electrolyte. The positive electrode electrolyte channel 8A includes a positive electrode-side inlet slit 23A and a positive electrode-side outlet slit 25A. The negative electrode electrolyte channel 9A includes a negative electrode-side inlet slit 24A and a negative electrode-side outlet slit 26A. The structures of the positive electrode electrolyte channel 8A and the negative electrode electrolyte channel 9A are formed to differ from each other. The structures that are made different may include slit lengths, cross-sectional shapes, cross-sectional areas, and the like.
