A fuel cell system includes an air compressor having an inlet fluidly coupled to ambient, a humidifier fluidly coupled to an outlet of the air compressor, a mass airflow sensor disposed downstream of the air compressor and upstream of the humidifier, a fuel cell stack having a cathode inlet fluidly coupled to an outlet of the humidifier, a differential pressure flow sensor disposed downstream of the humidifier and upstream of the cathode inlet of the fuel cell stack, and a controller programmed to control at least one of the air compressor and the fuel cell stack in response to humidity of airflow to the cathode inlet of the fuel cell stack as indicated by signals from at least the mass airflow sensor and the differential pressure flow sensor.
