<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell assuring high sealability when forming gas sealing by using a sheet or the like, and also to provide a method for manufacturing the same. <P>SOLUTION: In a conductive member 13, a gas seal layer 15 is joined so as to cover both end surfaces of an axial direction of a fuel cell tube 3, and the gas seal layer 15 consists of a first seal layer 25 of a side of the conductive member 13 and a second seal layer 27 laminated thereon. The first seal layer 25 and the second seal layer 27 are glass seal layers containing a crystal phase in a glass phase, and, in the seal layers 25 and 27, their volume ratios of the crystal phase are different respectively. Concretely, the first seal layer 25 contains glass as a principal component and a ceramic component of 5 to 40 vol.% as the crystal phase. On the other hand, the second seal layer 27 contains glass as a principal component and a ceramic component of 0 to 15 vol.% as the crystal phase. <P>COPYRIGHT: (C)2009,JPO&INPIT |
