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.
