a bypass valve positioned downstream of the compressor and upstream of the fuel cell, the bypass valve controllable to open in response to a control signal to allow at least a portion of airflow from the compressor to bypass the fuel cell and flow directly to the exhaust throttle valve or the exhaust pipe;
an intercooler downstream of the compressor and upstream of the bypass valve; and
a humidifier downstream of the bypass valve, wherein the bypass valve is configured to selectively direct at least a portion of the airflow from the intercooler to the exhaust pipe downstream of the throttle valve.
