SEAL STRUCTURE OF SOLID OXIDE FUEL CELL AND SEALING METHOD

摘要

PROBLEM TO BE SOLVED: To solve a problem of bonding and sealing between a unit cell and cell support foil in a low temperature operating type solid oxide fuel cell.

SOLUTION: Cell support foil is disposed on the top surface of the fringe of a unit cell formed by laminating an electrolyte membrane and an air pole one by one on a fuel electrode comprising a ceramic material containing a metal to form this seal structure of the low temperature operation type solid oxide fuel cell. The electrolyte membrane is formed on the top surface of the fuel electrode so that the top surface of the fringe of the fuel cell is exposed, and the exposed surface is brazed to the lower surface of the cell support foil by a brazing filler metal in this seal structure and the sealing method of the low temperature operating type solid oxide fuel cell.
