    Abstract: The present invention provides a novel manufacturing method for a solid oxide fuel cell apparatus in which members of the apparatus are joined together with an adhesive, such as a ceramic adhesive. The method implements first and second types of drying and hardening steps. The first type of step may be called a workable hardening step and gives an assembly of members in the solid oxide fuel cell apparatus structural rigidity to go through assembling of the solid oxide fuel cell apparatus. The second type of step may be called a solvent elimination and hardening step and gives the assembled members property to withstand the operation temperature of the solid fuel oxide cell apparatus. The first type of step is performed at a first temperature lower than a second temperature at which the second type of step is performed. The second type of step is performed only after the first type of step is performed at multiple times.

    Abstract: Provided is a method for producing a solid oxide fuel cell comprising the following: a fuel gas flow path, a fuel electrode layer provided around the fuel gas flow path and containing an iron group element and a ceramic, a solid electrolyte layer provided around the fuel electrode layer, and an air electrode layer provided around the solid electrolyte layer. In a high-temperature state where the temperature of the solid oxide fuel cell, in which a fuel gas is supplied from one side of the fuel gas flow path and exhausted through an opening provided on the other side of the fuel gas flow path, is close to a power generation temperature, the solid oxide fuel cell is subjected to a process for regulating oxidation expansion rate of the fuel electrode layer, the oxidation expansion occurring when an oxidant gas flows in through the opening. As a result, it has become possible to provide a solid oxide fuel cell in which cracks in the electrolyte and cell breakage are prevented even when air flows into the fuel electrode side at the suspension of operations of the fuel cell.
