Patent ID: 8652700

Claim:
A fuel cell comprising: an electrolyte electrode assembly which includes an anode electrode, a cathode electrode, and an electrolyte which is sandwiched between the anode electrode and the cathode electrode; a separator which includes a sandwiching portion that sandwiches the electrolyte electrode assembly; a fuel gas channel which is formed at a first surface of the sandwiching portion, and is covered by the anode electrode; fuel gas outlets which are formed outside the fuel gas channel in a radial direction of the fuel gas channel so that the fuel gas channel communicates with the outside of the fuel cell, and discharge a fuel gas inside the fuel gas channel to outside of the fuel gas channel; an oxygen-containing gas channel which is formed at a second surface of the sandwiching portion, and is covered by the cathode electrode; and oxygen-containing gas outlets which are formed outside the oxygen-containing gas channel in a radial direction of the oxygen-containing gas channel so that the oxygen-containing gas channel communicates with the outside of the fuel cell, and discharge an oxygen-containing gas inside the oxygen-containing gas channel to outside of the oxygen-containing gas channel, in which the oxygen-containing gas outlets are formed at phases different from phases of the fuel gas outlets in a circumferential direction of the sandwiching portion.
