    摘要： A fuel cell system is disclosed that employs an expander for recovering mechanical energy from a cathode exhaust fluid produced by the fuel cell system to generate torque. The expander is coupled to a shaft of a compressor with a freewheel mechanism, wherein the freewheel mechanism transfers the torque from the expander to the compressor when a rate of rotation of a driveshaft of the expander is greater than the rate of rotation of the shaft of the compressor, and selectively militates against the expander acting as a restrictor to the shaft of the compressor when a rate of rotation of the driveshaft of the expander is substantially equal to or less than a rate of rotation of the shaft of the compressor.

    摘要： A fuel cell system that determines the concentration of hydrogen gas in an anode loop. The fuel cell system includes at least one fuel cell, an anode inlet, an anode outlet, an anode loop, a source of hydrogen gas and an injector for injecting the hydrogen gas. First and second pressure sensors are provided in the anode loop and are spaced a known distance from each other. A controller responsive to the output signals from the first and second pressure sensors filters the sensor signals from the first and second pressure sensors and determines the concentration of hydrogen gas in the anode loop based on the time difference between the filtered sensor signal from the first pressure sensor and the filtered sensor signal from the second pressure sensor.

    摘要： A method for depositing a hydrophilic coating on flow field plates or bipolar plates and manifolds in a fuel cell stack after the stack is assembled. The method includes preparing a solution that contains hydrophilic nano-particles suspended in a suitable solvent. The cathode and anode inlet and outlet manifolds and the cathode and anode flow channels are filled with the solution. The solution is then pumped out of the stack using, for example, a stream of nitrogen. The stack is allowed to dry, using heat if desirable, to provide a film of the nano-particles formed on the anode and cathode flow channels and manifolds within the stack.

    摘要： A device and method to extract water from a moisture-rich fuel cell flowpath. A water transport unit is integrated into the fuel cell so that liquid water stagnation within flow channels and manifolds is reduced. In one embodiment, the device includes numerous flowpaths that include an active region and an inactive region. The water transport unit includes a hydrophilic member such that upon passage of a fluid with the excess water through the inactive region of the device flowpath and into the presence of the hydrophilic member, it absorbs excess water from the fluid.
