摘要： A system and method for operating a cooling fluid pump and cooling fluid heater in a vehicle when the vehicle is not being used so that the temperature of the cooling fluid does not drop to low in a cold environment. The system includes an AC connector for plugging the system into an AC power outlet. The system also includes AC/DC converter that converts the AC power to a DC signal suitable to operate the pump. The system also includes a temperature switch that closes if the ambient temperature falls below a predetermined temperature, which electrically connects the AC connector to the AC/DC converter. When the AC/DC converter is powered, a switch is closed to connect the pump to a pulse width modulation (PWM) generator to operate the pump. Further, when the temperature switch is closed, power is provided to the heater.

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 diagnostic method of detecting component failures in a fuel cell anode subsystem involves estimating fuel flow through injectors and comparing the estimated flow with a model based upon the system parameters. An observer based model is used to determine a residual value, the difference between the hydrogen input and the hydrogen consumed, and the residual is compared with a threshold range. In alternative embodiments, the stack current and the state of the valves are used to calculate the required hydrogen flow through the injectors and the duty cycle of an injector is compared to a tolerance range.

摘要： A system and method for drying a fuel cell stack after stack shutdown. In one embodiment, a cooling fluid is pumped through the fuel cell stack after the system is shutdown to use the heat still available in the cooling fluid immediately after shutdown to provide thermal equilibrium in the stack. In another embodiment, the heated cooling fluid still available immediately after system shutdown is sent through a cathode input gas heat exchanger so that drying air from the system compressor is heated by the cooling fluid before it enters the stack. In another embodiment, a separate heat exchanger is provided that receives the drying gas prior to it being sent into the fuel cell stack.
