Abstract

[Problem] To provide a stacked structure including electrodes that can effectively prevent misalignment between units. [Solution] A stacked structure 2 including electrodes 232, 332, 412, 233, 333, 422, wherein multiple units 23, 33, 24, 41, 42 including flat units are stacked and fastened by fasteners 25, the respective units 23, 33, 24, 41, 42 comprising frame-shaped fastening portions 237a, 237b, 337a, 337b, 247a, 247b, 417a, 417b, 427a, 427b on outer peripheral portions on both surfaces thereof, being stacked by the surfaces of the respective fastening portions 237a, 237b, 337a, 337b, 247a, 247b, 417a, 417b, 427a, 427b being pressed against each other, and being formed so that the width of fastening portions 247a, 247b, 337a, 337b, 427a, 427b on one unit is different from the width of fastening portions 237a, 237b, 417a, 417b on another unit.

First claim

The invention claimed is:

1. A stacked structure including electrodes, wherein multiple units including flat units are stacked and fastened by fasteners,
the respective units comprising frame-shaped fastening portions on outer peripheral portions on both surfaces thereof, being stacked by the surfaces of the respective fastening portions being pressed against each other, and being formed so that a width of fastening portions on one unit is different from a width of fastening portions on another unit;
the fastening portions comprising, on front surface sides thereof, gaskets comprising elastic members; and
outer edge portions on a side on which the width of the fastening portions is smaller being located further to the inside than outer edge portions on a side on which the width is larger, and inner edge portions on the side on which the width of the fastening portions is smaller being located further to the inside than inner edge portions on the side on which the width is larger.

2. The stacked structure including electrodes according to claim 1 , wherein diaphragms are provided between the stacked units, and the diaphragms are interposed between the fastening portions of the respective units.

3. The stacked structure including electrodes according to claim 1 , wherein the multiple units include a bipolar element and a middle chamber.

4. The stacked structure including electrodes according to claim 3 , wherein the multiple units are formed by stacking multiple sets of unit stacks wherein each set, as a single unit, is constructed by stacking, in the following order, a bipolar element, a middle chamber, and a bipolar element.

5. The stacked structure including electrodes according to claim 1 , wherein the multiple units are bipolar elements.

6. The stacked structure including electrodes according to claim 1 , wherein the multiple units include a cathode unit and an anode unit.

7. The stacked structure including electrodes according to claim 2 , wherein the multiple units include a bipolar element and a middle chamber.

8. The stacked structure including electrodes according to claim 2 , wherein the multiple units are bipolar elements.

9. The stacked structure including electrodes according to claim 2 , wherein the multiple units include a cathode unit and an anode unit.
