    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.

    摘要： A system includes a fuel cell stack, a power communication path, a first controller and a second controller. The fuel cell stack generates electrical power, and the power communication path is coupled between the fuel cell stack and a load of the system to communicate the electrical power to the load. The power communication path includes a switch, which is operable to selectively couple the fuel cell stack to the load and isolate the fuel cell stack from the load. The first controller has a first response time to control the fuel cell stack and control the power communication path. The second controller has a second response time, which is significantly less than the first response time to monitor the power communication path for a fault condition and take corrective action in response to detecting the fault condition.

    摘要： A technique that is usable with a fuel cell includes generating a humidified reactant flow. The technique includes measuring a rate of condensate production from the reactant flow and controlling the generation of the humidified reactant flow in response to the measured rate of condensate production.
