SOLID OXIDE FUEL CELL AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR SAME

摘要

The present invention is a method for manufacturing a solid oxide fuel cell apparatus for generating electricity by supplying fuel and oxidant gas to fuel cells housed in a fuel cell module, comprising: an adhesive application step for applying ceramic adhesive to the joint portions of constituent members so that the flow path carrying fuel or oxidant gas inside the fuel cell module are formed in an airtight manner; a workable hardening step for hardening the applied ceramic adhesive to a state capable of implementing the next manufacturing process; and a solvent elimination and hardening step wherein, after multiple repetitions of the adhesive application step and the workable hardening step, ceramic adhesive hardened in the workable hardening steps is dried to a state capable of withstanding temperatures during electrical generation.

1. A method for manufacturing a solid oxide fuel cell apparatus for generating electricity by supplying fuel and oxidant gas to fuel cells housed in a fuel cell module, comprising steps of:
an adhesive application step for applying ceramic adhesive to joint portions of constituent members so that flow path carrying fuel or oxidant gas inside the fuel cell module are formed in an airtight manner; and a drying and hardening step for drying the applied ceramic adhesive; wherein the drying and hardening step includes: a workable hardening step for hardening the applied ceramic adhesive to a state capable of implementing a next manufacturing process; a solvent elimination and hardening step in which, after multiple repetitions of the adhesive application step and the workable hardening step, solvent remaining within the ceramic adhesive are further eliminated and hardened from the ceramic adhesive which was hardened in all the workable hardening steps, and are dried to a state capable of withstanding the temperature rise in a startup procedure.
