Abstract

To provide a solid oxide fuel cell system in which fuel cells within a fuel cell module are connected in an airtight manner using ceramic adhesive. The invention is a solid oxide fuel cell system for generating electricity by reacting fuel and oxidant gas, including: a fuel cell module containing multiple fuel cells, and a fuel gas dispersion chamber for distributing and supplying fuel to each of the fuel cells, whereby each of the fuel cells is affixed in an airtight manner using ceramic adhesive to an affixing member forming the fuel gas dispersion chamber, and a gas leak suppression portion for suppressing the occurrence of cracks caused by shrinkage when a ceramic adhesive hardens is formed by the ceramic adhesive layer around the fuel cells.

Description

technical field [0001] The present invention relates to a solid oxide fuel cell device, and more particularly to a solid oxide fuel cell device that supplies fuel and oxidant gas to a plurality of fuel cell cells accommodated in a fuel cell module to generate power. Background technique [0002] Solid Oxide Fuel Cell (Solid Oxide Fuel Cell: hereinafter also referred to as "SOFC") uses an oxide ion conductive solid electrolyte as an electrolyte, installs electrodes on both sides, supplies fuel gas on one side, and supplies fuel gas on the other side. A fuel cell that supplies oxidant gas (air, oxygen, etc.) to the side and operates at a relatively high temperature. [0003] A fuel cell module constituting a solid oxide fuel cell device generally accommodates many fuel cells, and distributes fuel gas to each of these many fuel cells. The fuel gas distributed to each fuel cell is first supplied to a chamber called a fuel gas distribution chamber, and flows into each fuel cell ...
