a cell stack compressed between terminal structures defining ends of the redox flow battery, the cell stack formed of a plurality of cells, and wherein each cell of the plurality of cells includes:
a deformable positive electrode having a permeability based on a mechanical compression of the positive electrode and in face-sharing contact with a first face of a membrane separator;
a negative electrode configured to be less compressible than the positive electrode and arranged at a second face of the membrane separator opposite from the positive electrode; and
an electrolyte in contact with the positive electrode, the positive electrode having a first set of zones with a first permeability and a second set of zones with a second, lower permeability.
