A layered sintered body for an electrochemical cell which is a planar-type layered sintered body composed of an electrode and a separator stacked thereon, wherein a plurality of gas flow passages are formed by coupling grooves formed on the electrode and the separator. Even when this electrochemical cell is subjected to repetition of a cooling-heating cycle, an increase of internal resistance on and around the boundary between the separator and electrode can be restrained and layer separation and development of cracks at the joint boundary can be prevented.

A first method for manufacturing a solid oxide film having a highly densified solid oxide film having a small thickness and an improved electric conductivity; and a second method for manufacturing a solid oxide fuel cell in which a solid oxide film formed on an air electrode or a fuel electrode is manufactured by the first method. The solid oxide fuel cell according to the present invention is capable of generating a high power. The solid oxide film is formed on a substrate in such manner that a solid oxide material is sprayed on the substrate to form a sprayed solid oxide film thereon; Then a solution of metal compound including at least one metal selected from a group of manganese, iron, cobalt, nickel, copper and zinc is impregnated into the sprayed solid oxide film; and the sprayed solid oxide film is subjected to a heat treatment in order to increase an airtightness of the film. It may be possible to use a material for spraying, in which 1.about.10 parts by weight of an oxide of said metal is contained, instead of the impregnation, or to obtain a material for spraying by mixing the compound powder containing the metal and the solid oxide material in a spray gun via separately arranged powder supply devices.

摘要:
A method of producing a laminated body having a ceramic porous body having a thickness of 300 μm or larger and a ceramic dense body having a thickness of 25 μm or smaller. A green body for the porous body and a green body for the dense body are laminated to obtain a laminate, which is then subjected to pressure molding by cold isostatic pressing to obtain a pressure molded body. The pressure molded body is sintered to obtain a laminated sintered body. By reducing the leakage rate of helium gas of the laminated sintered body to 10−6 Pa˜m3/s or lower, the operational efficiency of the cell can be improved, and the deterioration of the cell can be prevented to improve an output after the cell is subjected to initiation and termination cycle tests of operation.
