摘要： The present invention relates to an electrochemical cell having the separator assembly that comprises a fluid distribution means comprising wicking material on the cathode side of a membrane electrode assembly (MEA). The wicking material transports liquids internally within the fuel cell; promotes humidification of the membrane; and provides a self-regulating cooling system for the fuel cell. The wicking material further forms gas flow channels for introducing gases to and from the MEA. Other preferred aspects of the present invention include methods of cooling the fuel cell by evaporation and/or vaporization at the cathode side.

摘要： A method and device for operating a fuel cell system. A recirculation loop coupled to a fuel cell cathode ensures that fluids passing through the cathode are recycled, thereby enabling reaction between residual oxygen in the recycled fluid and fuel that has been introduced into the recirculation loop until substantially all of the oxygen is reacted, leaving a substantially oxygen-free, predominantly nitrogen compound in the cathode and related flowpath. Thereafter, this compound can be redirected to purge the remaining residual hydrogen resident in the fuel cell's anode and related flowpath. While 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 catalysts supports.

摘要： The present invention provides a combustor for a fuel processor which integrates a burner and a catalyst. The burner is utilized to quickly heat the catalyst to a light-off temperature to prepare it for normal operation. The heated catalyst is then used to react anode exhaust with air or cathode exhaust under normal operation.

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.
