Document Type and Number:
WIPO Patent Application WO/2022/070486
Kind Code:
A1
Abstract:
Provided is a member for a fuel cell in which a lip 4b is directly fixed to the surface of a separator 5, wherein the lip 4b is a cross-linked body of a radical curable composition containing components (A) to (E) below at a specific ratio, and the glass transition temperature (Tg) of the cross-linked body is -30 °C or less. Thus, a seal member can firmly adhere to the surface of a base material for a fuel cell without using an adhesive, and furthermore, the seal member can be thinned and also have excellent sealing properties over a wide temperature range. (A) (Meth)acrylic polymer having a (meth)acryloyl group at a molecular chain end. (B) Monofunctional (meth)acrylic monomer having a glass transition temperature (Tg) of 0 °C or more and having a polycylic structure. (C) Monofunctional (meth)acrylic monomer except for component (B). (D) Polyfunctional (meth)acrylic monomer. (E) Radical polymerization initiator.
