DIMENSION MEASURING DEVICE FOR ELECTROLYTE MEMBRANE, AND METHOD FOR EVALUATING ELECTROLYTE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a dimension measuring device for an electrolyte membrane capable of automatically measuring the dimensions of the electrolyte membrane, and a method for evaluating the electrolyte membrane for evaluating characteristics of the electrolyte membrane using the dimension measuring device for the electrolyte membrane.

SOLUTION: The dimension measuring device for the electrolyte membrane comprises a first fixing means for fixing one end of the electrolyte membrane; a second fixing means for fixing the other end of the electrolyte membrane; a tension applying means capable of applying tension to the electrolyte membrane with both ends fixed by the first and second fixing means; a measuring means capable of measuring a distance between the first fixing means and the second fixing means; and a control means capable of controlling the operation of the tension applying means. Tension is applied to the electrolyte membrane through the tension applying means only when measuring the dimensions of the electrolyte membrane, and tension is not applied to the electrolyte membrane when not measuring the dimensions of the electrolyte membrane.
