A dense interconnector film is formed over a fuel electrode, while preventing calcium included in material for the interconnector from solid phase reaction with zirconia included in material for the fuel electrode. When forming the interconnector filmmade of lanthanum chromite-based perovskite type oxide which includes calcium in its composition includes calcium to the fuel electrodeof which composition includes zirconia, a intermediate layeris formed on the fuel electrode, by using (SrLa)(TiNb)O, and then onto the intermediate layer, the interconnector filmis formed.

Film-formed article and method for producing same

A cell of a flat plate solid oxide fuel cell has a first electrode member of porous material having pores through which all of a fuel gas or air passes. An electrolyte film is on either a front or a back surface of the first electrode member. A second electrode member is on the electrolyte film and a separator film is on the other surface of the first electrode member. The first electrode member is either a fuel electrode or an air electrode and the second electrode member is the other. Part of the electrolyte film and/or part of the separator film form seal portions which cover side surfaces between the electrolyte film and the separator film and function as gas seal films.

Unit cell of flat solid oxide fuel cell and fuel cell stack comprising the same

The strength of a cell stack is improved, and processing of components is facilitated to decrease the processing cost. Further, an output characteristic is enhanced, and the material cost is reduced. A single cell includes a fuel electrode (porous fuel electrode substrate) consisting of a porous substrate, an electrolyte film formed on one of a front surface and a back surface of the porous fuel electrode substrate an air electrode film formed on the electrolyte film a separator film formed on the other surface of the porous fuel electrode substrate and a porous air electrode substrate jointed to the air electrode film A stack is formed by laminating these single cells and attaching manifold plates on side surfaces.
