a fuel cell stack (FCS) configured to provide a stack power, the stack power being a product of a stack current and a stack voltage of the FCS, and the stack voltage inversely depending on the stack current; and

a controller configured to, in response to a stack power request, while the stack voltage is less than a predetermined threshold, adjust the stack current to a desired amount corresponding to the stack power request to cause the FCS to provide a stack power commensurate with the stack power request;

wherein the controller is further configured to, upon the stack voltage meeting or exceeding the predetermined threshold, increase the stack power request to an increased stack power request and adjust the stack current to an increased desired amount corresponding to the increased stack power request to cause the FCS to provide an increased stack power commensurate with the increased stack power request with the stack voltage, which inversely depends on the stack current, being decreased to be less than the predetermined threshold due to the stack current being increased to the increased desired amount, and the stack voltage being maintained to be less than the predetermined threshold due to the stack current being at the increased desired amount as the stack voltage inversely depends on the stack current.
