Metal-halogen flow battery cell, stack, system, and method, the stack including flow battery cells that each include an impermeable first electrode, an insert disposed on the first electrode and comprising sloped channels, a cell frame disposed around the insert and including a cell inlet manifold configured to provide a metal halide electrolyte and an opposing cell outlet manifold configured to receive the electrolyte, a porous second electrode disposed on the insert, such that sloped separation zones are formed between the second electrode and the channels, conductive connectors electrically connecting the first and second electrodes, and ribs disposed on the second electrode and extending substantially parallel to the channels of the insert. A depth of the channels increases as proximity to the cell outlet manifold increases.
