NOVELTY - Fuel cell (10) comprises an exhaust gas separation component (90) including an annular portion (92) formed around an outer circumferential portion of an electrolyte electrode assembly (26), where annular portion has an opening (100) for discharging a first exhaust gas, which has been consumed at one electrode of an anode (24) and a cathode (22) to an outside of the electrolyte electrode assembly; and a seal portion (94) provided at an end of the annular portion for preventing first exhaust gas from entering another electrode of the anode and the cathode.    USE - Used as a solid oxide fuel cell for stationary and mobile applications, e.g. for mounting on a vehicle.    ADVANTAGE - It is possible to prevent the partial (linear) contact between the separator and the electrolyte electrode assembly. It is possible to reliably prevent the power generation efficiency and the durability from being degraded due to combustion of the exhaust gas. The fuel gas and oxygen-containing gas flow uniformly. The uniform power generation reaction is achieved, and occurrence of heat distortion is reduced. Improvement of fuel gas utilization ratio is achieved.    DETAILED DESCRIPTION - Fuel cell formed by stacking an electrolyte electrode assembly and separators, the electrolyte electrode assembly including an anode, a cathode, and an electrolyte interposed between the anode and cathode, comprises an exhaust gas separation component provided between the separators, where exhaust gas separation component comprises an annular portion formed around an outer circumferential portion of the electrolyte electrode assembly, and having an opening for discharging a first exhaust gas, which has been consumed at one electrode of the anode and the cathode to the outside of the electrolyte electrode assembly; and a seal portion provided at an end of the annular portion for preventing the first exhaust gas from entering another electrode of the anode and the cathode.
