Internally manifolded flow cell for an all-iron hybrid flow battery
First Claim
1. A system for a flow battery flow cell stack, comprising:
- an internally manifolded flow battery cell stack, the internally manifolded flow battery cell stack including,a first flow field positioned at a first face of an internally manifolded frame, the first flow field comprising one of a redox electrode plate and a plating electrode plate,a plurality of inlet ports positioned at the first face less interiorly than the first flow field from a perimeter of the internally manifolded frame, a first of the plurality of inlet ports fluidly coupled to the first flow field by way of a first inlet flow path and each successive inlet port coupled to a different, sequentially arranged flow field, anda plurality of outlet ports positioned less interiorly than the first flow field from the perimeter of the internally manifolded frame, a first of the plurality of outlet ports fluidly coupled to the first flow field by way of a first outlet flow path and each successive outlet port coupled to a different, sequentially arranged flow field,wherein electrolytes from one of a redox electrolyte tank and a plating electrolyte tank flow to each of the plurality of inlet ports and electrolytes from each of the plurality of outlet ports flow to one of the redox and plating electrolyte tanks.

Abstract
In one example, a system for a flow cell for a flow battery, comprising: a first flow field; and a polymeric frame, comprising: a top face; a bottom face, opposite the top face; a first side; a second side, opposite the first side; a first electrolyte inlet located on the top face and the first side of the polymeric frame; a first electrolyte outlet located on the top face and the second side of the polymeric frame; a first electrolyte inlet flow path located within the polymeric frame and coupled to the first electrolyte inlet; and a first electrolyte outlet flow path located within the polymeric frame and coupled to the first electrolyte outlet. In this way, shunt currents may be minimized by increasing the length and/or reducing the cross-sectional area of the electrolyte inlet and electrolyte outlet flow paths.
