Abstract

The present invention relates to a technology for a jig for evaluating a solid oxide fuel cell, and more particularly, to a jig for evaluating a solid oxide fuel cell in which a press is formed in an upper plate and a lower plate of a jig which evaluates a characteristic of a fuel cell, so that gas leakage through a sealant and attachment strength of the sealant and a performance of a unit cell are simultaneously evaluated by using one jig.

First claim

The invention claimed is:

1. A jig module for a solid oxide fuel cell, the jig module comprising:
a lower jig which includes: a seating groove; a hydrogen supply pipe having one side connected to the seating groove; and a hydrogen discharge pipe having the other side connected to the seating groove;
an upper jig including an oxygen supply pipe and an oxygen discharge pipe;
a press unit which moves the upper jig and the lower jig in a vertical direction; and
a control unit which controls the vertical movement of the press unit,
wherein the upper jig is coupled to be fitted into the seating groove to form a sealed portion.

2. The jig module of claim 1 , wherein the upper jig is configured such that one side of the oxygen supply pipe and the other side of the oxygen discharge pipe communicate with each other toward the sealed portion.

3. The jig module of claim 1 , wherein the upper jig and the lower jig have cylindrical shapes.

4. The jig module of claim 1 , wherein valves which control flow rates of oxygen and hydrogen are provided at one end of each of the hydrogen discharge pipe and the oxygen discharge pipe.

5. The jig module of claim 1 , further comprising:
a measuring unit which measures, when a sealant is located in the seating groove, whether the gas is leaked through the sealant and attachment strength of the sealant.

6. The jig module of claim 1 , further comprising:
a measuring unit which evaluates, when a unit cell is located in the seating groove, a performance of the unit cell.

7. The jig module of claim 1 ,
wherein the control unit controls any one or more of a flow rate of oxygen which flows into the oxygen supply pipe, and a flow rate of hydrogen which flows into the hydrogen supply pipe.
