PROBLEM TO BE SOLVED: To provide an alkali-free glass joining material for a solid oxide fuel cell (SOFC), and an SOFC system comprising an alkali-free junction made of the joining material.SOLUTION: The solid oxide fuel cell system 100 comprises an SOFC 10 comprising a fuel electrode 12, an air electrode 16, and a solid electrolyte 14, and a gas pipe 20 joined to the SOFC 10 to supply gas. A junction 1 between the SOFC 10 and the gas pipe 20 is made of a glass comprising a glass matrix and a leucite crystal mixed in the matrix, and the glass matrix contains no alkaline components. |
