Fuel cell

A fuel cell comprising an electrolyte electrode assembly and first and second separators sandwiching the electrolyte electrode assembly, the electrolyte electrode assembly including a first electrode, a second electrode, and an electrolyte interposed between the first electrode and the second electrode, the second electrode having a surface area smaller than that of the first electrode, the first separator facing the first electrode, the second separator having outer dimensions different from those of the first separator, and facing the second electrode,

• wherein a first seal member, a second seal member, and a third seal member each comprise a tip and are formed integrally on one surface of the first separator;
• the tip of the first seal member contacts the electrolyte at an outer end of the electrolyte electrode assembly;
• the tip of the second seal member contacts an outer end of the second separator;
• and
• the tip of the third seal member that contacts an outer end of an adjacent separator, wherein the adjacent separator comprises a separator that is adjacent to:
• the second separator.
