The present disclosure generally relates to systems and methods for determining, managing, and/or controlling excess hydrogen flow in a system comprising a fuel cell or fuel cell stack and ejector based on the internal state of the ejector.

Systems and methods to measure or control fuel cell stack excess hydrogen flow using ejector mixing state

The present disclosure generally relates to systems and methods for operating a shutdown process in a fuel cell system including connecting a passive electrical load to a fuel cell stack in the fuel cell system before initiating the shutdown process, disconnecting a DC-DC converter by a system controller, initiating nitrogen blanketing after a current passing through the DC-DC converter is reduced to about zero, ensuring water content in the fuel cell stack is about zero, and sending a signal to the system controller to initiate the shutdown process.

Electrode pressure balance for a nitrogen blanketing process

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.

Fuel cell powertrain systems and methods for power split and allocation in fuel cell powertrain systems

A method includes detecting a change in a loading condition on an engine based on use of an implement system including a pump driven by the engine, an actuator fluidly coupled to the pump, and an implement repositionable with the actuator. The change in the loading condition is detected based on a variation in a command signal from a joystick that controls movement of the implement, an outlet pressure of the pump, a displacement of the pump, and/or an engagement signal of a clutch positioned to selectively couple the pump to the engine. The method further includes commanding a fueling system to increase an amount of fuel provided to the engine and/or an air handling system of the machine to increase an amount of air and/or a boost pressure of the air provided to the engine in response to detection of an increasing loading condition based on the variation.
