Abstract

The present invention relates to a firing cartridge, and more particularly, to a firing cartridge in which multiple slit grooves are formed in lateral portions positioned between an upper end portion and a lower end portion, and solid fuel cell electrodes are inserted into the slit grooves, such that the number of cells, which may be fired at the same time, is increased, and thus productivity of a solid fuel cell may be improved.

First claim

What is claimed is:

1. A firing cartridge comprising:
an upper end portion;
first and second lateral portions at opposing sides of the upper end portion, the first lateral portion comprising a first surface that comprises a plurality of first grooves, and the second lateral portion comprising a second surface facing the first surface of the first lateral portion, wherein the second surface of the second lateral portion comprises a plurality of second grooves; and
a lower end portion connected to the first and second lateral portions, the lower end portion being parallel to the upper end portion,
wherein the plurality of first grooves and the plurality of second grooves are arranged symmetrically, and a pair comprising one of the plurality of first grooves and one of the second grooves is configured to hold a unit cell for a solid fuel cell.

2. The firing cartridge of claim 1 , wherein the pair comprises a plurality of pairs that are configured to hold a plurality of unit cells for the solid fuel cell, respectively.

3. The firing cartridge of claim 1 , wherein the plurality of first grooves are spaced apart from one another, and the plurality of second grooves are spaced apart from one another.

4. The firing cartridge of claim 1 , wherein the plurality of first grooves are spaced apart from one another by a uniform distance, and the plurality of second grooves are spaced apart from one another by the uniform distance.

5. The firing cartridge of claim 1 , wherein the upper end portion and the lower end portion each have a quadrangular shape comprising an opening at a center thereof.

6. The firing cartridge of claim 1 , wherein the upper end portion, the lower end portion, and the first and second lateral portions each comprise a ceramic material.

7. The firing cartridge of claim 1 , further comprising:
a support comprising a ceramic material, the support being connected to both the upper end portion and the lower end portion and having a height equal to a height of each of the first and second lateral portions.

8. The firing cartridge of claim 1 , wherein the upper end portion is spaced apart from the lower end portion in a vertical direction, and
wherein the plurality of first grooves are spaced apart from one another in the vertical direction, and the plurality of second grooves are spaced apart from one another in the vertical direction.

9. The firing cartridge of claim 8 , wherein each of the upper end portion and the lower end portion has a thickness in the vertical direction in a range of from 0.1 cm to 10 cm.

10. The firing cartridge of claim 8 , wherein each of the upper end portion and the lower end portion has a thickness in the vertical direction in a range of from 1 cm to 8 cm.

11. The firing cartridge of claim 8 , wherein each of the first and second lateral portions has a thickness in a horizontal direction in a range of from 0.1 cm to 10 cm, and the horizontal direction is perpendicular to the vertical direction.

12. The firing cartridge of claim 8 , wherein each of the first and second lateral portions has a thickness in a horizontal direction in a range of from 1 cm to 8 cm, and the horizontal direction is perpendicular to the vertical direction.

13. The firing cartridge of claim 4 , wherein the uniform distance is in a range of from 100 μm to 3 cm.

14. The firing cartridge of claim 4 , wherein the uniform distance is in a range of from 1 mm to 1 cm.

15. The firing cartridge of claim 5 , wherein the opening of the upper end portion extends through the upper end portion in a thickness direction thereof, and the opening of the lower end portion extends through the lower end portion in a thickness direction thereof.

16. The firing cartridge of claim 7 , wherein the upper end portion is spaced apart from the lower end portion in a vertical direction, and the support extends in the vertical direction.
