Redox flow cell cell, redox flow cell cell stack, and redox flow cell

摘要

A redox flow battery cell comprising a positive electrode, a negative electrode, and a diaphragm interposed between the positive electrode and the negative electrode, wherein the positive electrode and the negative electrode overlap with each other via the diaphragm. A region and a non-overlapping region that does not overlap via the diaphragm in at least one of the positive electrode and the negative electrode, and the total area of the non-overlapping region is 0.1% or more of the area of the overlapping region. A redox flow battery cell that is 20% or less.
