Patent ID: 7521142

Claim:
A fuel cell separator having first and second surfaces, and comprising a low-elastic modulus layer (A) having a bending elastic modulus of 1.0×10 1 −6.0×10 3 MPa and a bending strain of 1% or more; and a high-elastic modulus layer (B) having a bending elastic modulus exceeding 6.0×10 3 MPa, wherein the low-elastic modulus layer (A) constitutes at least a part of one or both surfaces of the separator, wherein the layer (A) and/or layer (B) comprises an electroconductive resin composite material comprising 40-2 mass % of (a) resin binder, and 60-98 mass % of an electroconductive substance (b), and wherein the layer (A) comprises a component (a) including a thermoplastic or thermosetting resin composition of at least two components which comprises 20-99 mass % of an elastomer; and the layer (B) comprises a component (a) including a thermoplastic or thermosetting resin composition which comprises at least one kind of a crystalline polymer having a melting point of 100° C. or more, and/or an amorphous polymer having a glass transition point of 100° C. or more.
