<P>PROBLEM TO BE SOLVED: To provide a method of fabricating a flat oxide fuel battery cell, the method reducing warping of a single cell. <P>SOLUTION: The method includes: a step of forming a green laminate 10 by laminating an electrolyte sheet 3' on an electrode support body 2' formed in a sheet shape; and a step of forming a half cell composed of a sintered body by calcining the green laminate 10. The calcining step of the half cell includes a temperature elevating step and a temperature lowering step, and in the whole calcining step from the temperature elevating step to the temperature lowering step, a first load is added to the half cell. In the temperature lowering step, a second load is added to the half cell in addition to the first load. In the temperature lowering step, a temperature range in which the load is added to the half cell is decided as a range between the highest calcining temperature and at least a temperature in the vicinity of an operating temperature of the fuel battery cell by cooling down. <P>COPYRIGHT: (C)2011,JPO&INPIT |
