US Patent 7288334 Fuel cell stack and method of producing the same

A terminal plate of a fuel cell stack includes an electron conductive area and a passage area. The electron conductive area is connected to an anode. The passage area includes passages for supplying an oxygen-containing gas, a fuel gas, and coolant to a membrane electrode assembly. The electron conductive area is made of composite of foamed metal and insulating resin. The passage area is made of the insulating resin. The electron conductive area and the passage area are combined together by injection molding, for example.
