Abstract: A system including a flow straightener for a fuel cell cathode subsystem is provided. The system includes an intake manifold including a tube configured for providing an airflow to a compressor of the fuel cell cathode subsystem. The intake manifold includes an inlet configured for receiving the airflow into the intake manifold. The system further includes a mass air flow sensor disposed upon the intake manifold and a flow straightener disposed within the intake manifold between the inlet and the mass air flow sensor. The intake manifold includes an upstream portion between the flow straightener and the intake manifold inlet. The intake manifold further includes a downstream portion between the flow straightener and the mass air flow sensor. The flow straightener is configured for causing the airflow within the downstream portion to be less turbulent than the airflow within the upstream portion.
