    摘要： A fuel cell system includes a fuel cell stack, a reservoir, a water management circuit, a cooling circuit and a fan. The fuel cell stack communicates a reactant flow and communicates a water flow. The water management circuit is adapted to remove water from the reactant flow and store the water in the reservoir. The cooling circuit is adapted to generate the water flow that is communicated through the fuel cell stack from the water in the reservoir. The fan controls the amount of water that is removed from the reactant flow to regulate a water level of the reservoir and controls removal of thermal energy from the water flow regulate a temperature of the fuel cell stack.

    摘要： A fuel cell-based system including equipment not classified to operate in a flammable environment, a detector to detect a flammable gas, and a component capable of leaking a flammable gas are arranged in an enclosure. The component is positioned above the unclassified equipment and below the sensor, and a buoyancy path is provided such that the unclassified equipment is isolated from flammable gas emitted by the component in the enclosure while a ventilation system is not energized. In addition, the detector is placed in the buoyancy path so that when the system is started from a de-energized state, the detector can determine whether an unacceptable concentration of flammable gas is present in the enclosure. When the system is energized, the ventilation system creates an air stream through the enclosure. The ventilation system is arranged such that unclassified equipment is upstream of flammable gas that is emitted by the component in the enclosure.

    摘要： This application relates to a heat transfer apparatus and method employing an active regenerative cycle. The invention employs a working or “active” fluid and a heat transfer fluid which are physically separated. The working fluid is contained in an array of refrigeration elements that are distributed over the temperature gradient of a regenerative bed. The work for the refrigeration cycle is provided by alternative compression and expansion of the working fluid in each of the refrigeration elements at a temperature corresponding to the element's location in the temperature gradient. The compression and expansion strokes may be coupled together for optimum work recovery. The heat transfer fluid is circulated relative to the working fluid between a thermal load and a heat sink to enact a refrigeration cycle having improved energy efficiency.
