摘要： Systems and methods for initiating use of, or starting up, fuel cell stacks in subfreezing temperatures. The fuel cell stacks include a thermal management system that is adapted to deliver a liquid heat exchange fluid into thermal communication with a fuel cell stack, such as to heat the stack during startup of the stack when the stack is at a subfreezing temperature or operated in a subfreezing environment. In some embodiments, the thermal management system includes a heat exchange circuit that is configured to provide delivery of the liquid heat exchange fluid to the fuel cell stack even when the conduits are at a subfreezing temperature. In some embodiments, the fuel cell system is configured to deliver liquid heat exchange fluid from the fuel cell stack and heat exchange circuit when the thermal management system is not being utilized.

摘要： Fuel cell systems that perform maintenance hydration by supplying power to satisfy at least part of an applied load from an energy-consuming assembly while a primary power source is in electrical communication with and available to supply power to the energy-consuming assembly to satisfy the portion of the applied load being satisfied by the fuel cell system. In some embodiments, a fuel cell system may determine a start time, or start condition, for maintenance of the fuel cell system. The fuel cell system then may be activated from an inactive condition according to the start time, or start condition, by initiating delivery of at least fuel, and optionally oxidant, to a fuel cell stack of the system. Power then may be supplied from the activated fuel cell system at an output voltage that is higher than a voltage at which power from the primary power source is being supplied, such that the applied load is satisfied, at least in part, by the power from the fuel cell system instead of the power from the primary power source. Upon operation of the fuel cell system for a period sufficient to rehydrate the fuel cell stack, operation of the fuel cell system may be discontinued, with the primary power source resuming supplying power to satisfy the applied load from the energy-consuming assembly.

摘要： Pressure swing adsorption (PSA) assemblies with optimized startup times, as well as to hydrogen-generation assemblies and/or fuel cell systems containing the same, and methods of operating the same. Startup and shutdown methods for a PSA assembly, and optionally an associated fuel processing system, are disclosed to provide for shortened startup times. The PSA assemblies may be in fluid communication with a hydrogen source that may be used or otherwise configured or controlled to purge the PSA adsorbent columns of adsorbents during startup and/or shutdown procedures, the hydrogen source additionally or alternatively may be used or otherwise configured or controlled to charge the columns with hydrogen for idling in a pressurized state. The use of this hydrogen source, together with specific startup and shutdown methodologies, provides for reducing the startup time of the PSA assembly.
