Abstract:
A fuel cell stack includes an endplate assembly of a fuel cell system which includes a structural endplate having a first exterior surface and a first interior surface located on an opposite side of the endplate relative to the first exterior surface. An insulator plate has a second exterior surface contacting the first interior surface of the structural endplate and second interior surface on an opposite side of the insulator plate relative to the second exterior surface. A third plate has a third exterior surface contacting the second interior surface and a third interior surface on an opposite side of the third plate relative to the insulator plate. The third interior surface and third exterior surface are substantially flat such that third interior surface and the third exterior surface are about parallel to each other. The second interior surface and the third exterior surface contact each other substantially continuously in a longitudinal direction and a lateral direction such that the second interior surface and the third exterior surface are flat and substantially parallel to each other. The second exterior surface is contoured such that the second exterior surface is not flat and is substantially non-parallel relative to the third interior surface.

Claim (Index 7):
A method for forming a fuel cell endplate system comprising;\n assembling an endplate assembly by connecting a structural endplate, a second insulator plate, and a third plate to each other by a plurality of fasteners applied to the structural endplate; the structural endplate having a first exterior surface and a first interior surface located on an opposite surface of said endplate relative to said first exterior surface; the insulator plate having a second exterior surface contacting said first interior surface of said structural endplate and a second interior surface on an opposite surface of said insulator plate relative to said second exterior surface; the third plate having a third exterior surface contacting said second interior surface and a third interior surface on an opposite side of said third plate relative to said insulator plate; the third interior surface and said third exterior surface being substantially flat such that said third interior surface and said third exterior surface are about parallel to each other; said second interior surface and said third exterior surface contacting each other substantially continuously in a longitudinal direction and a lateral direction such that said second interior surface and said third exterior surface are flat and substantially parallel to each other; said second exterior surface being contoured such that said second exterior surface is not flat and is substantially non-parallel relative to said third interior surface.
