A solid oxide fuel cell includes a cathode, a solid ceramic electrolyte, and an anode comprising a cermet containing an environment tolerant catalyst, such as a fuel starvation andor a sulfur tolerant catalyst. For its prevention, the thin film sheet 2 and a bonding ring 6 are bonded in a state where a tensile force is applied only to the central region IA of the thin film sheet 2, and a tensile force is not applied to an outer peripheral region OA. Parameters of the calls to the stop functions that are references to the external resources are identified.
