Abstract
A cell stack (700) as provided enables a flowing electrolyte battery to have a reduced size and weight. The cell stack (700) includes a casing having a positive polarity end and a negative polarity end. A plurality of half cells (805) are inside the casing, and each half cell (805) includes an electrode plate (705), an adjacent separator plate (715), and at least one capillary tube (727) positioned between the electrode plate (705) and the adjacent separator plate (715). The capillary tube (727) has a first end extending outside of the half cell (805) and a second end located inside the half cell (805). At least one manifold (530) is in hydraulic communication with a plurality of capillary tube ends including the first end of the capillary tube (727) in each half cell (805). The capillary tube (727) in each half cell (805) enables electrolyte to circulate through the plurality of half cells (805) via the at least one manifold (530).
