Solid oxide electrolyte fuel cell

A solid oxide electrolyte fuel cell comprising:

• a power generation film having opposing sides and a periphery, said power generation film comprising a solid oxide electrolyte film, an oxygen electrode formed on one side of said solid oxide electrolyte film, and a fuel electrode formed on the other side of said solid oxide electrolyte film, and said power generation film having a plurality of dimples projecting from each of said opposing sides;
• two interconnectors, one provided on each of said opposing sides of said power generation film;
• and
• a sealing section located at and integrally formed with said periphery of said power generation film, said sealing section defining openings therein and having opposing faces effective to join said power generation film to said two interconnectors at said opposing faces of said sealing section and said dimples projecting from said opposing sides;
• wherein the material composing said sealing section has the same coefficient of thermal expansion as said solid oxide electrolyte film.
