PROBLEM TO BE SOLVED: To provide a manufacturing method for a fuel battery substrate and a manufacturing method for a fuel battery cell stack that are capable of keeping operation even when a dense film (solid electrolyte and interconnector) is damaged.SOLUTION: A manufacturing method for a fuel battery substrate of the present invention includes: a process of previously acquiring, with respect to substrate material including any amount of NaO, data obtained by associating a baking temperature with a shrinkage factor in the case of baking a body prepared by using the material; a process of measuring a Na content of the substrate material, collating the Na content of the material with the data, and deriving a baking temperature for making the shrinkage factor be in a desired range; and a process of preparing a body by using the material to bake the body at the derived baking temperature.SELECTED DRAWING: Figure 1 |
