Abstract: PURPOSE: A measuring method of the acid resistance of a separator for a polymer electrolyte fuel cell is provided to quantitatively and qualitatively measure acid resistance without direct application to a unit cell. CONSTITUTION: A measuring method of acid resistance of a separator for a polymer electrolyte fuel comprises: a step of dipping a material for the fuel cell separator in an acid solution, and filtering the same; a step of using the acid solution as a base solution to measure the absorbance of a filtering solution; and a step of quantitively analyzing the acid resistance thereof by calculating the erupted amount of a resin from the material for the fuel cell separator. The measurement step of the absorbance measures UV-Vis spectrums. The acids solution is a phosphate solution.
