Abstract: A fuel cell system including a combined injector/ejector system. The pressure of a hydrogen gas being injected into the fuel cell system by the injector acts as a pump that draws an anode exhaust gas being carried by the ejector back into the fuel cell system. The respective gases mix together in proximity to the ejector prior to being introduced back into the fuel cell system. A pressure controller can be provided to control the pressure of the hydrogen gas applied to the injector to more effectively draw the anode exhaust gas. In this manner, the need for a separate pump for the ejector, and the energy required for its operation, is eliminated or at least lessened, thus increasing the overall energy efficiency of the fuel cell system.

Abstract: A process for manufacturing a compressed gas tank that includes a combination of an injection molding process and a rotomolding process. In a first step, a boss to be positioned in the opening of an outer structural layer of the tank is provided and a thin portion of the liner is injection molded to the boss so that a channel within the boss is filled with the liner material to increase the seal integrity between the boss and the liner. Once the liner material is hardened, the surface of the injection molding liner portion is cleaned. Next, a rotomolding process is performed to mold the remaining portion of the liner to the boss. During the rotomolding process, the injection molded portion of the liner melts to be part of the liner made during the rotomolding process.

Abstract: A system and method for controlling hydrogen gas flow to an anode side of a fuel cell stack using a pressure regulator in the event that an injector that normally injects the hydrogen gas into the fuel cell stack has failed in a stuck open position. During normal operation, the control of the injector is determined based on the pressure of an anode sub-system and the position of the pressure regulator is determined based on a supply pressure between the pressure regulator and the injector. If it is determined that the injector is stuck in an open position, then the position of the pressure regulator is controlled to the anode pressure instead of the supply pressure. If the pressure regulator is an electrical pressure regulator, then it is pulsed to mimic normal system operation. Alternately, another valve, such as a shut-off valve, can be employed to provide the flow pulsing.

Abstract: A method and system for automatically calibrating a pressure sensor in a hydrogen storage system for a fuel cell vehicle. A low-range pressure sensor in the fuel cell system, which has much greater accuracy at low pressure readings, is used to calibrate a high-range pressure sensor in the hydrogen storage system. This calibration can only be done when a pressure regulator situated between the two sensors is in a fully open position. In such a condition, the high-range sensor can be calibrated to the value of the low-range sensor, thus improving the accuracy of the high-range sensor's readings. The calibration can be a simple setting of the high-range sensor to the value of the low-range sensor under static conditions, or the calibration can be done while gas is flowing from the hydrogen storage system to the fuel cell by accounting for the pressure drop between the two sensors.

Abstract: A resettable thermal pressure relief device (TPRD) is disclosed. The TPRD includes a piston, a housing adapted to receive the piston and allow movement between an open and a closed position. The housing includes an actuator having a temperature sensitive material disposed therein. The temperature sensitive material volumetrically expands, increasing a length of the actuator and forcing a lever from a first position to a second position. The piston is held in the closed position by the lever in the first position. When the lever moves to the second position, the piston is allowed to move to the open position, allowing a fluid to flow through the TPRD from a high pressure vessel in communication therewith.
