Abstract

The chamber frame element of the present invention, which has a smaller amount of voltage drop, consumes less reactive power than the prior art, and exhibits no metal corrosion, is a chamber frame element ( 14 ) for an electrolyzer or an electrodialysis cell. The chamber frame element ( 14 ) includes: a bag body ( 141 ); a frame ( 142 ) housed in an interior space of the bag body ( 141 ); and an inlet ( 143 ) and an outlet ( 144 ) to which piping can be attached, which are formed on the outer side of a region where the frame is housed in the bag body ( 141 ).

First claim

The invention claimed is:

1. A chamber frame element for an electrolyzer or an electrodialysis cell, the chamber frame element comprising:
a bag body;
a frame housed in an interior space of the bag body; and
an inlet and an outlet to which piping can be attached, the inlet and the outlet being formed on the outer side of a region where the frame is housed in the bag body.

2. The chamber frame element according to claim 1 , wherein the chamber frame element is made of a resin.

3. The chamber frame element according to claim 1 , wherein the frame comprises a flow path that allows a liquid inflowing from the inlet to flow inside the frame and a liquid inside the frame to flow to the outlet.

4. The chamber frame element according to claim 3 , wherein the flow path is a groove or a channel that communicates to the outside and the inside of the frame, or the frame is formed of a porous material.

5. The chamber frame element according to claim 1 , wherein the chamber frame element is for a three-chamber electrolyzer.

6. An electrolyzer comprising the chamber frame element according to claim 1 .

7. An electrodialysis cell comprising the chamber frame element according to claim 1 .

8. An electrolyzer comprising the chamber frame element according to claim 2 .

9. An electrolyzer comprising the chamber frame element according to claim 3 .

10. An electrolyzer comprising the chamber frame element according to claim 4 .

11. An electrolyzer comprising the chamber frame element according to claim 5 .

12. An electrodialysis cell comprising the chamber frame element according to claim 2 .

13. An electrodialysis cell comprising the chamber frame element according to claim 3 .

14. An electrodialysis cell comprising the chamber frame element according to claim 4 .

15. An electrodialysis cell comprising the chamber frame element according to claim 5 .
