Claims

What is claimed

1. A frame plate assembly for a redox cell stack, the frame plate assembly comprising:

a cell plate; and

a frame assembly coupled in fluidic communication to the cell plate, wherein the frame assembly is configured to at least partially surround a perimeter of the cell plate and to channel at least one flow of electrolytes to the cell plate, the frame assembly comprising at least two frame segments, wherein each frame segment of the at least two frame segments comprises:

a body having a first end and a second end;

an extension connection element disposed at the first end; and

a receiver connection element disposed at the second end, wherein two adjacent frame segments are configured to interlock via the extension connection element being received in the receiver connection element.

2. The frame plate assembly of claim 1, wherein the frame assembly comprises three frame segments.

3. The frame plate assembly of claim 1, wherein the frame assembly comprises four frame segments.

4. The frame plate assembly of claim 1, wherein each frame segment further comprises:

at least one frame channel defined in the body and configured to channel the at least one flow of electrolytes therethrough;

at least one plug extending from the body and configured to be at least partially received in the cell plate; and

at least one electrolyte pathway defined in the body and extending between the at least one frame channel and the at least one plug such that the at least one flow of electrolytes is channeled between the cell plate and the at least one frame channel.

5. The frame plate assembly of claim 4, wherein the at least one electrolyte pathway comprises an electrolyte shunt pathway.

6. The frame plate assembly of claim 4, wherein the at least one plug is unitary with the body.

7. The frame plate assembly of claim 4, wherein the at least one frame channel is defined by a sealing element extending from the body.

8. The frame plate assembly of claim 4, wherein the at least one frame channel is defined in a removable corner member configured to removably attach to the body.

9. The frame plate assembly of claim 1, wherein each frame segment of the at least two frame segments further comprises at least one plate connector configured to couple the frame segment to the cell plate.

10. The frame plate assembly of claim 1, wherein the cell plate comprises at least two plate members, and wherein each frame segment of the at least two frame segments is bonded to the corresponding plate member.

11. The frame plate assembly of claim 1, wherein the cell plate is configured to float about 0.6 inches with respect to the frame assembly.

12. A method of assembling a frame plate assembly for a redox cell stack, the frame plate assembly including a cell plate and a frame assembly, the method comprising:

forming at least two frame segments of the frame assembly;

coupling each frame segment of the at least two frame segments in fluidic communication to the cell plate; and

interlocking adjacent frame segments such that the frame assembly at least partially surrounds a perimeter of the cell plate.

13. The method of claim 12, wherein forming the at least two frame segments further includes injection molding each frame segment.

14. The method of claim 13 further comprising post machining each frame segment.

15. The method of claim 12, wherein forming the at least two frame segments further includes compression molding each frame segment.

16. The method of claim 12, wherein forming the at least two frame segments further includes additively manufacturing each frame segment.

17. The method of claim 12 further comprising:

stacking two or more frame plate assemblies; and

coupling each frame plate assembly of the two or more frame plate assemblies in fluidic communication, wherein the stack of two or more frame plate assemblies form at least a portion of the redox cell stack.

18. The method of claim 12 further comprising:

forming at least one removable corner member; and

coupling the at least one removable corner member to each frame segment.
