CRACK DETECTION METHOD OF SEPARATOR FOR FUEL CELL AND CRACK DETECTION DEVICE OF SEPARATOR FOR FUEL CELL

PROBLEM TO BE SOLVED: To provide a crack inspection method of a separator for a fuel cell having a simple inspection process and to provide a crack inspection device of the separator. SOLUTION: A pressing member 2a arranged in an outer peripheral part 1a of a separator 1 for a fuel cell and a pressing member 2b arranged in a through hole 1b for a manifold are deformed by a force applied from the thickness direction. A crack 1d of the separator 1 for the fuel cell is detected by utilizing difference between force F1 by which the pressing member 2a of the outer peripheral part 1a is pressed toward the through hole 1b for the manifold and force F2 by which the pressing member 2b inside the through hole 1b for the manifold is pressed toward the outer peripheral part 1a.
