Solid oxide electrolyte fuel cell

摘要

A solid oxide electrolyte fuel cell comprises a power generation film consisting of a solid oxide electrolyte film dimpled over substantially the whole area on both sides thereof, an oxygen electrode formed on one side thereof, and a fuel electrode formed on the other side of thereof, and comprises a pair of interconnectors located on both sides of the power generation film. Furthermore, this invention adopts a seal structure for sealing each side of the power generation film to each of the corresponding interconnectors. The peripheral area of the power generation film is provided with a seal face with the interconnector and is formed to lie in essentially the same plane as the apices of the dimpled pattern formed on the power generation film, and the provided seal section has approximately the same thermal expansion coefficient as the solid oxide electrolyte film which forms the power generation film.
