  • Patent number: 10193176
    Abstract: The disclosure provides a system and method for synthesizing ultra-pure hydrogen from biomass waste. The present invention comprises a gasifier, an oils and tars filter, a steam generator, a water gas shift reactor (“WGS”), a heat-exchange two-phase water separator, a scrubber, a hydrogen separator, and fluid conduits in fluid communication with the various system components, which together convert hydrocarbon-based biomass, e.g., woodchips, into ultra-pure hydrogen gas. Fluid conduits connect the gasifier and the steam generator, separately, to the WGS, the WGS to the two-phase separator, the two-phase separator to the scrubber, and the scrubber to the hydrogen separator, which further comprises an outlet port through which hydrogen gas may flow free of carbon monoxide. The hydrogen may flow to a device that utilizes hydrogen to generate energy, such as a hydrogen fuel cell or to an internal combustion engine.

  • Patent number: 7205062
    Abstract: A fuel cell pack includes multiple stacked membrane-electrode-assemblies and two base plates sandwiching the membrane-electrode assemblies and each configured to provide a uniform distribution of compressing forces across juxtaposed surfaces of the membrane-electrode-assemblies to eliminated external and internal gaseous leaks.
