1. A system comprising:
a fuel cell stack (FCS); and
a controller having a power model of the FCS that is configured to provide an estimated power that the FCS will output in response to being controlled according to a given stack current request, the estimated power being different than an actual power that the FCS outputs in response to being controlled according to the given stack current request; and
the controller configured to adjust a stack current of the FCS to a desired amount to cause the FCS to provide a power commensurate with a power request, wherein the controller employs the power model of the FCS in adjusting the stack current by adjusting the power request according to a difference between the estimated power that the FCS will output in response to being controlled according to a request for the stack current and the actual power that the FCS outputs in response to being controlled according to the request for the stack current.
