Metal support and solid oxide fuel cell including the same

Abstract

Disclosed are a metal support for a solid oxide fuel cell and the solid oxide fuel cell including the metal support. The metal support is coupled to a separator of the solid oxide fuel cell by welding and supports one surface of a unit cell comprising a fuel electrode, an air electrode, and an electrolyte layer interposed between the fuel and air electrodes, wherein the metal support is in the form of a plate and has a welding portion welded to the separator on the outer circumference thereof and a hollow portion surrounded by the welding portion to allow a fuel gas or air to flow therethrough. The use of the metal support increases the mechanical strength of the solid oxide fuel cell, resulting in improved durability and extended service life of the solid oxide fuel cell. In addition, the metal support ensures a smooth flow of the fuel gas or air, resulting in an increase in the sealing efficiency and energy production efficiency of the solid oxide fuel cell.
