<P>PROBLEM TO BE SOLVED: To provide an anticorrosive property estimation method with high reliability capable of quickly estimating the anticorrosive property of a metal separator of a fuel cell at a low cost. <P>SOLUTION: A test piece manufactured by making a perfluorosulfonic acid film itself directly contact with the metal separator is formed, and the test piece is kept in testing temperature of 60°C or higher and relative testing humidity of 70% or higher. After testing, the anticorrosive property of the metal separator is quickly and simply estimated by analyzing the concentration of the metal element captured in the perfluorosulfonic acid film. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
