A method for inspecting a metal separator includes a step of detecting deflection of the metal separator with a height detector, a step of displacing the metal separator or an imaging device in a height direction according to the deflection of the metal separator to keep a distance between the imaging device and an imaging portion of the metal separator constant, and a step of imaging a weld portion with the imaging device.

Method for inspecting metal separator

A method for inspecting a membrane electrode structure () which includes a first step in which detection medium capable of detecting elements of a first electrode catalyst layer () and a second electrode catalyst layer () and an element of a metal foreign matter () is sent along a thickness direction from the side of a first electrode layer () to a second electrode layer () side to obtain a thickness direction profile of a detection signal, and a second step in which an analysis unit identifies a thickness direction position of the metal foreign matter (), from intensity of the detection signal in the thickness direction profile, and in which the analysis unit identifies thickness direction positions of the first and second electrode catalyst layer ()(), or a thickness direction position of an electrolyte membrane (), from the intensity of the detection signal in the thickness direction profile.
