NOVELTY - A galvanic electrochemical cell (100, 500, 600) comprises a 1st cylinder-like collector (106, 506, 606) for connecting to an external electrical circuit (114), a 2nd cylinder-like collector (108, 508, 608) for connecting to the external circuit and located within the 1st current collector to define a gap (118, 518, 618) between the current collectors, units (128, 130, 136, 142, 536, 538, 636, 638) for circulating fluid electrolytes in the gap, and a cylinder-like filter (120, 414, 520, 620) located in the gap.    USE - A galvanic electrochemical cell for converting chemical energy into electrical energy (claimed) or storing electrical energy as chemical energy.    ADVANTAGE - Improved galvanic cells incorporating high molecular weight, non-Newtonian electrolytes, TVF, and circular Couette flows (CCF) are provided, a simple, low-cost mechanical filter that can keep decorated carbon particles in the anolyte and catholyte from crossing their respective electrolyte chambers and cross-contaminating other electrolytes is used, and high shear rates and large mass transport coefficients are attained.
