Abstract: A system and method for fluidly sealing a cylinder head interface between an engine block and a cylinder head of an internal combustion engine. An example apparatus includes a perimeter seal disposed on an outer periphery of the cylinder head. The perimeter seal has a first surface to abut a cylinder head sealing surface and a second surface to abut an engine block sealing surface. The perimeter seal is configured to prevent fluid from an external environment from entering the cylinder head interface and to allow fluid within the cylinder head interface to vent to the external environment when the fluid is above a predetermined pressure. A first fluid transfer tube seal fluidly seals a first fluid transfer orifice extending between the engine block and the cylinder head. The perimeter seal and the first fluid transfer tube seal are formed as a unitary structure.

Abstract: The present disclosure generally relates to systems and methods for implementing power a power split between a first and a second power source in a fuel cell powertrain system. The method includes receiving an input into a processor of the fuel cell powertrain system, determining an output by the processor, communicating the output by the processor to a system controller and determining a power split by the system controller. The first power source includes a fuel cell system and the second power source is selected from a battery system or an engine, and the input includes a life or health of at least one of the first power source or the second power source.

Abstract: A filtration system for a fuel cell hybrid propulsion system includes a first stage filter, a second stage filter positioned downstream of the first stage filter, and a third stage filter positioned downstream of the second stage filter and configured to be positioned upstream of a fuel cell system. The first stage filter has first pores with a first mean pore size. The second stage filter has second pores with a second mean pore size. The third stage filter has third pores with a third mean pore size. The second mean pore size is less than the first mean pore size. The third mean pore size is less than or equal to the second mean pore size. The first, second, and third stage filter are structured to filter an airflow prior to being received by the fuel cell system.
