Abstract: An air handling system for a fuel cell stack includes a pneumatic storage device disposed downstream from a compressor, a flow control valve system configured to operatively couple an inlet of the pneumatic storage device to an outlet of the compressor and configured to operatively couple an outlet of the pneumatic storage device to an inlet of the fuel cell stack, and a controller configured to, in response to a power demand being greater than a threshold, cause the flow control valve to open to increase a flow rate of air from the pneumatic storage device to the fuel cell stack.

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.
