Nondestructive thickness measurement method of hydrogen ion exchange strengthened film for fuel cell of three-layer structure

摘要

The present invention relates to a method for measuring non-destructive thickness of an enhanced film, and more specifically, a three-way structure wherein a hydrogen ion exchange enhanced membrane for a fuel cell includes a pure layer on one side and another side of a reinforcing substrate layer, and a position analysis process can be omitted through a thickness peak of the power spectrum of each layer; This paper describes a non-destructive thickness measuring method of a reinforcing film capable of non destructive total inspection.
