Abstract:
A solid oxide electrolyte fuel cell, comprising:a planar power generation film including a solid electrolyte layer, an oxygen electrode formed on a first surface of the solid electrolyte layer, and a fuel electrode formed on a second surface of the solid electrolyte layer, said film having a pair of first opposing sides and a pair of second opposing sides substantially perpendicular to the first opposing sides;a first interconnector facing the fuel electrode and forming a first space between one side the first interconnector and the fuel electrode;a second interconnector facing the oxygen electrode and forming a second space between one side of the second interconnector and the oxygen electrode;a fuel gas inlet aperture for supplying fuel gas into the first space, the fuel gas inlet aperture being provided in a vicinity of the one of the first opposing sides of the power generation film between the first interconnector and the fuel electrode substantially along an entire length of the one of first opposing sides;a fuel gas outlet aperture for exhausting the fuel gas from the first space, the fuel gas outlet aperture being provided in a vicinity of another of the first opposing sides of the power generation film between the first interconnector and the fuel electrode substantially along an entire length of the another of the first opposing sides;an air inlet aperture for providing oxidant gas into the second space, the air inlet aperture being provided in a vicinity of the one of the second opposing sides of the power generation film between the second interconnector and the oxygen electrode and having about half a length of one of the second opposing sides at a position adjacent the fuel gas inlet aperture; andan air outlet aperture for exhausting the oxidant gas from the second space, the air outlet aperture being provided in a vicinity of another of the second opposing sides of the power generation film between the second interconnector and the oxygen electrode and having about half a length of the another of the second opposing sides at a position adjacent the first fuel outlet aperture.
