Fuel cell including sealing member with acid-modified olefin adhesive layer containing metal deactivator

Abstract

The present disclosure provides a fuel cell having a sealing member having a high sealing performance even in a high temperature and highly acidic environment. One aspect of the present disclosure relates to a fuel cell including a sealing member. The fuel cell including a sealing member includes a substrate layer, a tie layer arranged on a surface of the substrate layer, and an acid-modified olefin adhesive layer that is arranged on a surface of the tie layer and contains a metal deactivator. The acid-modified olefin adhesive layer contains the metal deactivator in an amount in a range of from 300 ppm to 8,000 ppm. The metal deactivator is a compound represented by Formula (I): In the formula, R1 and R2 are each independently a monovalent group containing a substituted or unsubstituted aryl.

Dependencies are inferred from the claim text.
