    摘要： System for thermally conditioning, humidifying and filtering reactant feed gases supplied to a stack of fuel cells using an evaporative element, a water spray mechanism and a heat exchanger. The evaporation element also functions as a filter. The evaporative element may take the form of a removable packing (filter media). Use of a controller to manage the rate of nebulized water addition to the feed gas stream is also described. Benefits in filter efficiency and extended filter service life along with volume, weight, and cost reduction in a fuel cell system are realized.

    摘要： A hydrogen blower is provided and includes a housing having a drive unit and a compressor unit disposed therein. The drive unit is separated from the compressor unit by a neutral chamber, whereby the neutral chamber effectively seals the drive unit from the compressor unit. The drive unit includes a drive shaft, whereby the drive shaft extends generally between the drive unit and the compressor unit to selectively drive the compressor. In addition, the drive shaft fixedly supports a series of fan blades such that rotation of the drive shaft imparts a pressure on the neutral chamber to effectively seal the drive unit from the compressor unit. In this manner, the drive motor, compressor, and drive shaft may be packaged in a single housing while effectively sealing the drive unit from the compressor unit through cooperation between the fan blades and the neutral chamber.

    摘要翻译： 设置氢气鼓风机并且包括具有设置在其中的驱动单元和压缩机单元的壳体。 驱动单元通过中性室与压缩机单元分离，由此中性室有效地将驱动单元与压缩机单元密封。 驱动单元包括驱动轴，由此驱动轴大致在驱动单元和压缩机单元之间延伸，以选择性地驱动压缩机。 此外，驱动轴固定地支撑一系列风扇叶片，使得驱动轴的旋转在中性室上施加压力以有效地将驱动单元与压缩机单元密封。 以这种方式，驱动马达，压缩机和驱动轴可以被封装在单个壳体中，同时通过风扇叶片和中性室之间的协作有效地将驱动单元与压缩机单元密封。

    摘要： A fuel cell stack receiving oxidant into a compressor progressively pressurizing the oxidant from an inlet pressure to a discharge pressure where a fluid connection exists between oxidant effluent from the fuel cell stack and the progressively pressurized oxidant within the compressor at an intermediate pressure between the compressor inlet pressure and the compressor discharge pressure. A pressure regulator is provided for managing pressure of the cell oxidant effluent recycle flow to the compressor, and measurements are taken of compressor power consumption and/or compressor discharge temperature, humidity, and/or pressure to further control the regulator.
