PROBLEM TO BE SOLVED: To solve a problem in that, in a conventional fuel battery cell, strength is not imparted to an electrode layer after manufacturing, therefore, improvement has been demanded to increase the strength of the electrode layer.SOLUTION: To manufacture a fuel battery cell 1 having a structure sandwiching an electrolyte layer 2 between a pair of electrode layers 3, 4, and in which a metal support 5 is joined to the one electrode layer 3, the one electrode layer 3, electrolyte layer 2, and the other electrode layer 4 are formed on the surface of the metal support 5 while a formation area A for at least the electrode layer 2 of the metal support 5 is bent and deformed in a spherical shape. After the formation of the electrolyte layer 2 and electrode layers 3, 4, these are flattened. Thereby, residual compression stress can be applied to at least one electrode layer 3. Thus, tensile-resisting load performance for the electrode layer 3 can be improved. Accordingly, the fuel battery cell 1 having an electrode layer 3 excellent in strength can be obtained.SELECTED DRAWING: Figure 1 |
