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.

Abstract: A housing for an air-handling system includes a first housing shell and a second housing shell. The first housing shell includes a first casing portion and a tub portion monolithically formed. The tub portion is formed at a bottom of the main housing and includes a floor and a third sidewall. The second housing shell includes a casing portion configured to cooperate with the first casing portion to enclose a source air flow conduit of the main housing. The first housing shell further includes a first engaging feature circumscribing the first casing portion and the tub portion, and the second housing shell further includes a second engaging feature circumscribing the second casing portion. The first engaging feature is configured to cooperate with the second engaging feature to align the first housing shell and the second housing shell.
