Abstract
A member for a fuel cell in which a lipis directly fixed to the surface of a separator. In the member for a fuel cell, the lipis a cross-linked body of a radically 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. (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 polycyclic structure. (C) Monofunctional (meth)acrylic monomer except for component (B). (D) Polyfunctional (meth)acrylic monomer. (E) Radical polymerization initiator.
