Abstract
A flow-field plate for a flow stack in a flow cell battery system is described. The flow-field plate includes first electrolyte channels formed in a molded plate to direct a first electrolyte to a first flow-field on a first side of the molded plate and second electrolyte channels formed in the molded plate to direct a second electrolyte to a second flow-field on the second side of the molded plate.
Claims23
A flow-field plate in a flow-cell stack structure, comprising:
- a molded plate having a first side and a second side;
- first electrolyte channels formed in the molded plate to direct a first electrolyte to a first flow-field on the first side of the molded plate;
- and
- second electrolyte channels formed in the molded plate to direct a second electrolyte to a second flow-field on the second side of the molded plate.
1 more element
A flow-field plate, comprising
- a molded plate having a first side and a second side;
- a first electrolyte flow structure formed in the molded plate directing a first electrolyte through first electrolyte channels formed in both the first side and the second side through a first side flow field;
- a second electrolyte flow structure formed in the molded plate directing a second electrolyte through second electrolyte channels formed in both the second side and the first side through a second side flow field;
- and
- sealing structures formed around the first electrolyte channels and the second electrolyte channels.
2 more elements
A flow-stack, comprising:
- a plurality of flow-field plates, each of the plurality of flow-field plates include first electrolyte channels formed in the plate to direct a first electrolyte to a first flow field and second electrolyte channels formed in the plate to direct a second electrolyte to a second flow field;
- one or more membranes formed to fit within a depression in a corresponding one of the plurality of flow-field plates, each of the one or more membranes arranged such that the first flow field of one of the plurality of flow-field plates direct the first electrolyte across a first surface of membrane and the second flow field of an adjacent one of the plurality of flow-field plates directs the second electrolyte across a second surface of the membrane;
- bipolar-plates formed to fit within the depression in corresponding ones of the plurality of flow-field plates such that each of the one or more membranes is between bipolar plates;
- carbon felts positioned between the bipolar plates and the membranes;
- and
- a plurality of gaskets, each of the gaskets formed to engage adjacent pairs of the plurality of flow-field plates and seal the electrolyte channels.
