Abstract
A fuel cell includes electrolyte electrode assembly and separators. An exhaust gas separation member is provided between the separators. The exhaust gas separation member includes an annular portion formed around an outer circumferential portion of the electrolyte electrode assembly, a seal portion fixed to the annular portion and sandwiched between the outer end of the electrolyte electrode assembly and one of the separators, and a stopper provided integrally with the annular portion and fixedly engaged with the other separator.
Claims23
A fuel cell formed by stacking an electrolyte electrode assembly and separators, said electrolyte electrode assembly including an anode a cathode and an electrolyte interposed between said anode and said cathode, said fuel cell comprising:
- an exhaust gas separation member provided between said separators, wherein
- said exhaust gas separation member comprises:
- an annular portion formed around an outer circumferential portion of said electrolyte electrode assembly, and having an opening for discharging a first exhaust gas which has been consumed at one electrode of said anode and said cathode to the outside of said electrolyte electrode assembly;
- and
- a seal portion provided at an end of said annular portion for preventing the first exhaust gas from entering another electrode of said anode and said cathode.
