20 Claims

1. An assembly for fuel cell comprising:

an adhesive resin layer containing a polyolefin having at least one group selected from the group consisting of an acidic group and an acid anhydride group and having an acid value of 0.01 mgKOH/g to 6.5 mgKOH/g; and

two or more members bonded with the adhesive resin layer interposed therebetween,

wherein at least one of the members is a metal member having a ratio of a dipole term in surface free energy of 0.01% to 5.0%, and

wherein a relationship between the surface free energy γ_Mof the metal member and surface free energy γ_Aof the adhesive resin layer satisfies γ_M−γ_A≥5.0 mN/m.
