摘要： 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.
