A fuel cell stack includes an endplate assembly having a structural endplate. An insulator plate has a second exterior surface contacting a first interior surface of the structural endplate and a second interior surface on an opposite side of the insulator plate. 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. The second interior surface and the third exterior surface contact each other substantially continuously in a longitudinal direction and a lateral direction, and 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.

Fuel cell stack

A fuel cell system includes a fuel cell stack and a reactant temperature conditioner. The conditioner includes a fuel inlet for receiving fuel from a fuel source and an oxidant inlet for receiving oxidant from an oxidant source. The conditioner is configured to transfer heat energy from the oxidant to the fuel to arrive at a conditioned oxidant and a conditioned fuel. The conditioner has a fuel outlet coupled to the fuel cell stack to allow flow of the conditioned fuel to the fuel cell stack and an oxidant outlet to allow flow of the conditioned oxidant to the fuel cell stack.
