1. A method of operating a fuel cell system comprising a plurality of fuel cells and a plurality of auxiliary components located in at least one cabinet, comprising:

  • monitoring, by a control unit, a parameter of the fuel cell system;

    determining whether the parameter has violated a threshold;

    in response to determining that the parameter has violated the threshold, varying an auxiliary bus voltage by a first amount, a common auxiliary bus connected to each of the auxiliary components such that each of the auxiliary components experiences the variation in auxiliary bus voltage, the auxiliary components including a fan and at least one of an electronic circuit, a glow plug, a blower, a thawing heater, a pump or a valve;

    determining whether the auxiliary bus voltage has reached a voltage limit, the voltage limit preventing overloading of one of the auxiliary components; and

    varying the auxiliary bus voltage to the plurality of auxiliary components by a second amount in response to determining that the auxiliary bus voltage has not reached the voltage limit.
