摘要： A model uses various operating characteristics of a fuel cell to predict the relative humidity profile that is occurring within the fuel cell as a function of the reaction progress. The model is used to predict the relative humidity profile that will occur in response to changes to one or more of the operating characteristics of the fuel cell. A high frequency resistance of the fuel cell can also be used as a measure that is indicative of the humidity within the fuel cell. The model and/or the high frequency resistance can be used in a closed-loop feedback system to control the operation of the fuel cell to maintain the humidification of the MEA and fuel cells within a desired range to achieve a desired fuel cell performance.

摘要： A fuel cell system that includes an over-arching algorithm for providing a strategy that reduces relative humidity cycling of the cathode outlet gas between wet and dry operation to extend the useful life of the membrane. The algorithm receives sensor signals indicative of operating parameters of the fuel cell system. The algorithm maintains a cathode exhaust gas relative humidity in a wet operating mode if the operating parameters of the fuel cell system are able to sustain the cathode gas relative humidity above a first predetermined value, and maintains the cathode exhaust gas relative humidity in a dry operating mode if the operating parameters of the fuel cell system are able to sustain the cathode gas relative humidity below a second predetermined value.

摘要： A device and method for operating a fuel cell system. The device includes a combustor that is configured to combine reactants used in the fuel cell in such a way as to produce an inert fluid used to inert electrodes within the fuel cell. The device also includes componentry to permit purging of the electrodes subsequent to their inerting. In one form, the combustor is of such thermal mass that heat generated by combustion of the reactants is substantially absorbed by the combustor such that recourse to supplemental cooling apparatus is not required. The combustor may also be configured to promote staged mixing and subsequent reaction of the fuel cell reactants to further limit excess heat generated by the reaction. While the device of the present invention is usable during any period of system operation, it is especially valuable for operational conditions associated with starting up and shutting down a fuel cell system to inhibit the formation of high voltage potentials that could otherwise damage fuel cell catalysts or catalyst supports.

摘要： The present invention provides for a method and apparatus for hydrogen detection and dilution. The present invention uses an enclosure within which a variety of components of a fuel cell system are located and a ventilation stream to vent the enclosure which is induced by operation of a compressor that also is operable to supply the oxygen to the fuel cell system. The ventilation stream is directed through an outlet in the enclosure that contains a hydrogen sensor that is operable to both detect the presence of hydrogen and to consume hydrogen within the ventilation stream prior to being exhausted from the enclosure. The ventilation stream, alternatively, can be induced by operation of a fan driven by a motor which operates independently of the operation of the oxidant delivery system.

摘要： A method to produce a catalytic bed is initiated by forming apertures in a predetermined pattern on a strip or segment of thin foil. A pattern of desired channels is formed into the apertured foil, for example, as a herringbone pattern. The patterned foil is heat treated, and the surfaces of the foil are provided with at least one washcoat and at least one catalyzed coat, and cured. Cured foil in strip form is rolled into a multi-layer coil, or cured foil in segment form is stacked in multiple segment layers, to produce a desired geometric shape of the catalytic bed. The channels between layers of foil are offset in each successive layer to preclude channel nesting. The offset channels and apertures provide turbulent longitudinal and radial flow of a desired material throughout the catalytic bed.
