Abstract

An electrolyte membrane thickness measurement apparatus includes a detecting medium supplying portion configured to emit a detecting medium, a detecting portion configured to detect a metal catalyst, and an analyzing unit. A thickness direction profile of a detection signal is generated by the detecting portion, and first and second inflection points are determined in the thickness direction profile based on the intensity of the detection signal by the analyzing unit. The distance between the first and second inflection points is evaluated as the thickness of the electrolyte membrane by the analyzing unit.
