摘要： A system and method for regulating the pressure within a volume between a pressure regulator and an injector that injects hydrogen gas into the anode side of a fuel cell stack. The method includes delaying a copy of the a pulsed signal that controls the opening and closing of the injector a predetermined period of time and provides a bias signal from a look-up table that is determined by a desired average mass flow of the hydrogen gas flow to the fuel cell stack and the pressure at an upstream location of the hydrogen gas flow from the pressure regulator. The method selects the bias signal as a pressure regulator control signal that controls the pressure regulator when the delayed pulse injector signal is high and selects an arbitrary value at or near zero as the pressure regulator control signal when a delayed pulse injector is low.

摘要： A method for producing a spiral link fabric with a plurality of spirals joined to one another in an overlapping manner, with a plurality of seam wires stitched into overlapping regions of adjacent spirals and connecting the spirals to one another to form a flat structure, and with a plurality of packing elements introduced into free cross sections of the spirals, wherein the flat structure runs through a thermofixing operation before or after the introduction of the packing elements. The spirals are joined together to form the flat structure such that, before the thermofixing operation, the result is a clear width, as viewed in the plane of the flat structure, for the free cross sections of the spirals connected to one another to form the flat structure, which clear width is larger than a clear height of the free cross section of each spiral.

摘要： High pressure gas vessels can have a sensitivity to temperature of the compressed gas. Over-temperature conditions in particular may cause decreased durability and/or vessel damage, including gas leakage to the environment. Articles of manufacture, methods, and systems are provided for over-temperature protection using a passive device. The passive closing device does not require electrical power and no controller, sensors, or wiring is needed. This affords cost savings in comparison to other systems. Pressure vessels using the passive closing device can protect themselves, independent of the compressed gas fueling station configuration.

摘要： A technique for determining the relative humidity of the cathode input airflow to a fuel cell stack that eliminates the need for a dew-point sensor. The cathode input airflow is humidified by a water vapor transfer unit that uses water in the cathode exhaust gas. The technique employs an algorithm that determines the flow of water into the cathode inlet of the stack. In one embodiment, the algorithm determines the volume flow of water through the water vapor transfer unit using the Arrhenius equation, and then converts the water volume flow to a water mole flow. The algorithm then uses the water mole flow through the water vapor transfer unit and the water mole flow of ambient air to determine the water mole flow into the cathode inlet. The algorithm then uses the water mole flow into the cathode inlet to determine the relative humidity of the cathode airflow.

摘要： A system and method for waking up a vehicle controller during a hydrogen gas refueling process for a high pressure hydrogen storage tank on a fuel cell vehicle. The system includes a first temperature switch mounted to the high pressure tank and enclosed within an insulation housing for monitoring the temperature within the tank and a second temperature switch for monitoring the temperature of the hydrogen gas at the refuel receptacle, where the second temperature switch is also enclosed within an insulation housing. If the temperature within the tank increases above a predetermined temperature, the first switch will close, and if the temperature at the refueling receptacle falls below a predetermined temperature, then the second switch will close, which causes a wake up signal to be provided to the controller to allow the controller to monitor the temperature of the tank.

摘要： Systems and methods to diagnose valve leakage in a vehicle storing gaseous fuel in two or more vessels. A valve regulating the flow of the gaseous fuel from one of the vessels is closed and reopened, while the other vessels are providing gaseous fuel during a full run. The pressure spike from reopening the valve is analyzed to determine the rate of pressure change. Pressure spikes having a rate of change lower than a threshold parameter are indicative of a leaking valve.

摘要： A valve for a pressure vessel system includes a housing having a cavity defined by an inner surface of the housing. The housing further includes a rod aperture and a pair of fluid flow ports. An actuator is disposed adjacent the housing. The valve also includes a piston having a rod coupled to a piston head. The piston head is disposed in the cavity of the housing, and the rod disposed through the rod aperture. The rod is also coupled to the actuator. A ring seal is disposed between the piston head and an inner surface of the housing. The ring seal biases the piston head toward one of the fluid flow ports and seals the one of the fluid flow ports to close the valve when the actuator is deactivated. The ring seal is elastically deformed and the fluid flow ports are opened when the actuator is activated.

摘要： A system for controlling the power output of a fuel cell stack and a battery in a hybrid fuel cell system. The system includes a power damping filter that receives a power request signal, and damps the request to reduce large changes in the power request. A battery state of charge controller receives the difference between a battery state of charge set-point and the actual battery state of charge, and provides a battery power signal that attempts to maintain the battery state of charge at the set-point. The damped power signal and the battery power signal are added to generate a system power demand signal that satisfies the driver power request using the battery power and fuel cell stack power, and uses the fuel cell stack power to charge the battery during low power transients or if the battery state of charge is below the set-point.
