Abstract
A fuel cell includes an electrolyte electrode assembly and separators. A first protection layer is formed on a surface of an anode of the electrolyte electrode assembly facing the separator for preventing the anode from being exposed to an exhaust gas. A second protection layer is formed on a surface of the separator facing the anode for preventing the separator from being exposed to the exhaust gas. The first protection layer and the second protection layer tightly contact each other in part so as to form a space as a fuel gas channel for supplying a fuel gas to the anode. Alternatively, a protection layer is formed on an end surface of the separator facing the anode for preventing the separator from being exposed to the exhaust gas.
