    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 method for filling a fuel cell anode supply manifold with hydrogen prior to a start-up operation to facilitate a substantially even hydrogen distribution across the fuel cell is disclosed. The anode supply manifold is in fluid communication with a source of hydrogen. A first valve in fluid communication with the anode supply manifold and a second valve in fluid communication with an anode exhaust manifold are initially in a closed position while hydrogen is supplied to the anode inlet conduit to pressurize the fuel cell stack. The first valve is then opened to purge at least a portion of a fluid from the anode supply manifold to facilitate a filling of the manifold with hydrogen.
