Abstract:
1. A fuel cell comprising: an electrolyte electrode assembly including a pair of electrodes and an electrolyte interposed between said electrodes; separators for sandwiching said electrolyte electrode assembly, a reactant gas supply passage and a reactant gas discharge passage extending through said separators in a stacking direction, at least one of said separators having a reactant gas flow field connected between said reactant gas supply passage and said reactant gas discharge passage for supplying a reactant gas to one of said pair of electrodes; a seal member provided around said one of said pair of electrodes for sealing said reactant gas flow field, said reactant gas supply passage, and said reactant gas discharge passage; and a filling seal partially provided at an outer region of said one of said pair of electrodes, said filling seal being provided tightly in contact with at least an outer end surface of said one of said pair of electrodes for preventing leakage of said reactant gas, wherein the seal member and the filling seal contact the electrolyte.
