<P>PROBLEM TO BE SOLVED: To provide an end plate for a fuel cell stack capable of manufacturing inexpensively by comparatively simple manufacturing processes, and with high flexibility of a shape design of a circulation hole for gas or refrigerant, and to provide a manufacturing method thereof. <P>SOLUTION: The end plate E1 for a fuel cell stack is provided with a circulation hole partitioning part 10 with a circulation hole 11, and a metal-made body 20 containing at least a part of the circulation hole partitioning part 10. The circulation hole partitioning part 10 is a cast formed with a corrosion-resistant metal having more excellent corrosive resistant than a metal constituting the body part 20. The body 20 is molded by casting afterwards with the circulation hole partitioning part 10 cast beforehand, and thus, the circulation hole partitioning part 10 and the body part 20 are integrated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
