PROBLEM TO BE SOLVED: To provide an assembly arranged so that the deterioration of a brazing filler metal can be prevented by means of suppressing the occurrence of void even when being used in an atmosphere such that void is produced; and a solid oxide fuel battery having the assembly used therein.SOLUTION: The assembly 41 has: a first member made of metal, which is composed of an isolation separator 37; a second member composed of a cell main body 5 including ceramic as one primary component; and a bonding part 39 having a first bonding layer 67 on the side of a hydrogen atmosphere and a second bonding layer 69 on the side of an oxygen atmosphere, and bonding between the first and second members. The oxygen diffusion coefficient of the second bonding layer 69 is smaller than that of the first bonding layer 67. Therefore, in a case where the assembly 41 is used at a high temperature, even if hydrogen diffuses into the first bonding layer 67 from the side of the hydrogen atmosphere, oxygen is hard to diffuse from the side of the oxygen atmosphere into the second bonding layer 69. Hence, the occurrence of void owing to the reaction between hydrogen and oxygen in the assembly 41 can be suppressed, and the occurrence of void can be prevented from deteriorating a brazing filler metal. |
