    摘要： A method and apparatus for determining which condition in a fuel processor has initiated a shutdown of the fuel processor are disclosed. In general, the apparatus generates a plurality of shutdown initiator signals, each corresponding to one of a plurality of shutdown conditions and indicating whether such condition is present. The shutdown initiator signals are read within a predetermined window. At least one of the read shutdown initiator signals indicates that a corresponding first shutdown condition has occurred and identifies the corresponding first shutdown condition as the firstout.

    摘要： The present invention provides a method and apparatus for controlling a level in a receptacle capable of storing a fluid. The apparatus includes a first valve governing ingress of the fluid to the receptacle, a second valve governing egress of fluid from the receptacle, wherein the second valve is positioned below the first valve. The apparatus also includes a first switch deployed between the first valve and the second valve, wherein the first switch is capable of providing a first signal indicative of fluid at the first switch and a second switch deployed between the first switch and the second valve, wherein the second switch is capable of providing a second signal indicative of an absence of fluid at the second switch. The apparatus also includes a controller capable of controlling a fluid level in the receptacle by opening and closing the first and second valves responsive to the first and second signals.

    摘要： An apparatus and method for the preferential oxidation of carbon monoxide in a hydrogen-rich fluid. The apparatus utilizes one or more reactors that are dimensioned to optimize the exothermic oxidation reaction and the transfer of heat to and from the catalyst bed. A reactor of the apparatus has an elongated cylindrical catalyst bed and heat transfer means adjacent the catalyst bed. The heat transfer means is suitable for pre-heating the catalyst bed during start-up operations and for removing the heat from the catalyst bed during the oxidation reaction. One or more reactors of different dimensions may be utilized depending upon the pressure of the hydrogen-rich fluid to be directed into the apparatus and the pressure requirements for the carbon monoxide-depleted fluid exiting the apparatus. For instance, in low pressure operations where it may be desirable to minimize the pressure drop across the apparatus, two or more reactors having relatively smaller dimensions can be utilized. In higher pressure operations where pressure drop across the preferential oxidation apparatus is of less concern, a single reactor having larger dimensions may be utilized. The relatively narrow dimension of the catalyst bed coupled with the relatively large surface are used for heat transfer provides for more uniform temperatures within the catalyst bed and improved temperature control of the bed.
