摘要： A coolant reservoir and associated multi-functional unit for a thermal sub-system of a fuel cell system. The coolant reservoir includes a flame arrester positioned in a gas region of the reservoir. The multi-functional unit includes a first pressure relief valve that automatically opens if the pressure within the gas region goes above a first predetermined pressure. The multi-functional unit may also include a second pressure release valve that quickly releases pressure in the coolant reservoir if the pressure within the gas region goes above a second higher predetermined pressure. The multi-functional unit also includes an air-line and a check valve for allowing ambient air to enter the gas region if the pressure within the gas region falls below ambient pressure. The multi-functional unit also includes a cooling fluid fill line having plumbing that causes the coolant reservoir to vent prior to a cooling fluid cap being removed.

摘要： 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.

摘要： A liquid hydrogen storage system having minimized tanking losses. Hydrogen is discharged from a liquid hydrogen tank through connector piping of a filling connector to a discharge pipe and then to an external device, such as a fuel cell. As such, the connector piping is maintained at a cryogenic temperature substantially that of liquid hydrogen. During refilling of the tank through the already cryogenically cold connector piping there is substantially reduced evaporation of the liquid hydrogen provided by a liquid hydrogen tank station.

摘要： A fuel cell system that employs one or more injectors in an anode inlet unit for providing hydrogen flow control to a fuel cell stack in the system. At a low flow rate, the duty cycle of one of the injectors is controlled and the other injectors are closed. As the flow rate requirements increase, the duty cycle of the first injector is increased until it is completely open. The duty cycles of the other injectors are then controlled in the same manner in succession. The anode inlet unit may include a valve for directing the hydrogen supply gas to other devices in the fuel cell system. Additionally, a valve can be provided in the unit that receives a flow of air to purge the anode side of the fuel cell stack.

摘要： 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.
