    摘要: A parallel dual stack fuel cell system having anode recirculation includes a first fuel cell stack and a second fuel cell stack. Each of the first and second fuel cell stacks includes a gas outlet line connected to an anode outlet unit. The anode outlet unit functions to release wet H2/N2 gaseous mixture from the system. A second water separator is provided between the anode outlet unit and gas inlet lines to the first and second fuel cell stacks to increase removal of water droplets prior to a recirculation pump.

    摘要: A system and method for detecting a low performing cell in a fuel cell stack using measured cell voltages. The method includes determining that the fuel cell stack is running, the stack coolant temperature is above a certain temperature and the stack current density is within a relatively low power range. The method further includes calculating the average cell voltage, and determining whether the difference between the average cell voltage and the minimum cell voltage is greater than a predetermined threshold. If the difference between the average cell voltage and the minimum cell voltage is greater than the predetermined threshold and the minimum cell voltage is less than another predetermined threshold, then the method increments a low performing cell timer. A ratio of the low performing cell timer and a system run timer is calculated to identify a low performing cell.

    摘要: A method of treating fly ash which has a moisture content and which also has a high carbon particle content includes the steps of heating the fly ash to a temperature sufficient to break the bond between the fly ash and the carbon particles caused by the moisture content, applying the heated fly ash in a relatively thin layer to the surface of a belt-type conveyor and subjecting the layer of heated fly ash to the effects of an electrostatic charging zone while repeatedly mechanically rearranging the orientation of the fly ash particles in the zone for causing the carbon particles to take a charge and become attracted to an electrode so that the same may be separated from the layer. Apparatus for separating carbon particles from fly ash includes a generally horizontal conveyor, and a hopper which applies fly ash to be treated in a layer on the surface of a conductive belt. The belt carries the fly ash layer through an elongated electrostatic charging zone, and beaters beneath the belt impart a vibration to the belt for causing the fly ash layer to be in a state of agitation. The belt forms a lower electrode, while an upper electrode is spaced above the belt and the entire separation zone is environmentally enclosed to exclude ambient air and moisture from the separating zone. Collection bins are positioned along the lateral sides of the belt for capturing carbon particles discharged from the zone, while the accepts are delivered off of the end of the belt into a suitable bin.

    摘要: A system and method for correcting a large fuel cell voltage spread for a split sub-stack fuel cell system. The system includes a hydrogen source that provides hydrogen to each split sub-stack and bleed valves for bleeding the anode side of the sub-stacks. The system also includes a voltage measuring device for measuring the voltage of each cell in the split sub-stacks. The system provides two levels for correcting a large stack voltage spread problem. The first level includes sending fresh hydrogen to the weak sub-stack well before a normal reactive bleed would occur, and the second level includes sending fresh hydrogen to the weak sub-stack and opening the bleed valve of the other sub-stack when the cell voltage spread is close to stack failure.

    摘要: A system and method for putting a fuel cell vehicle system into a stand-by mode where there is little or no power being consumed, the quantity of fuel being used is minimal and the fuel cell system is able to quickly recover from the mode. The method includes determining whether predetermined stand-by mode vehicle level entrance criteria have been satisfied at a vehicle control level and predetermined stand-by mode fuel cell level entrance criteria have been satisfied for a fuel cell system control level, and putting the vehicle in the stand-by mode if both the vehicle level entrance criteria and the fuel cell level entrance criteria have been satisfied. The method exits the stand-by mode if predetermined vehicle level exit criteria have been satisfied or predetermined fuel cell level exit criteria have been satisfied.

    摘要: A fuel cell system including a compact, low-pressure-drop, high efficiency water-separator for separating liquid water from water-laden streams of the system. A cyclonic separator includes a sump for collecting the water, a drain for removing the water from the sump and directing it to a reservoir, a shutoff valve associated with the drain for controlling flow through from the drain, and a water level switch that controls the opening/closing of the valve. The switch triggers closing of the valve before the sump is emptied to provide a water seal that prevents escape of gas through the drain.
