Filed:

Dec 12, 2008

Appl. No.:

12/334040

International Classification:

H01M 8/04

US Classification:

429431, 429454

Abstract:

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.

US Classification:

429433, 429400, 429408, 429427, 429429, 429440

Abstract:

A system and method for quickly heating a fuel cell stack at fuel cell system start-up. The fuel cell system includes a three-way valve positioned in the anode exhaust that selectively directs the anode exhaust gases to the cathode input of the fuel cell stack so that hydrogen in the anode exhaust gas can be used to heat the fuel cell stack. During normal operation when the fuel cell stack is at the desired temperature, the three-way valve in the anode exhaust can be used to bleed nitrogen to the cathode exhaust.

International Classification:

F16K 31/02

US Classification:

25112915

Abstract:

A valve for a fuel cell system includes a valve housing having a valve seat formed therein. The valve seat includes an orifice formed therein to permit a fluid to flow through the valve housing. A movable member is disposed in the valve housing and is movable between an open position and a closed position. The movable member includes a first end having an elongate portion and a generally conical shaped base. At least a portion of the base is disposed in the orifice of the valve seat when the movable member is in the closed position to militate against a formation of ice across the orifice of the valve seat.

International Classification:

B07C 504
B07C 5342
G01N 1500

US Classification:

436 63

Abstract:

This invention relates to a method and apparatus for flexibly controlling sorting decisions for a flow cytometer or similar instrument at a purity vs. yield ratio of sorted particles, particularly at high event rates. The system monitors distances between sequential objects to determine if they are in close enough proximity to be within a single resolution unit of the sorting device. The "friend" or "foe" status of neighboring events is considered by this system in dealing with detected "coincident" events. The system operates on information of the desirability to sort the object, i. e. droplet, based upon the properties of the individual object. A storage and retrieval method is provided for making the information available at the time a sort operation based on a sorting logic condition is performed. Accordingly, an easily reconfigurable mode of operation control is provided to allow customized sorting strategies, based on the needs of individual applications or experiments. This system may be included as an integral part of a flow cytometer/cell sorter or similar instrument and may also be provided as an outboard module to such systems.

International Classification:

G01N 3300
B07C 502

US Classification:

422 73

Abstract:

A system for sorting particles is arranged such that the presence or absence of multiple parameters is determined for each particle in a flow of particles, and a logic condition is determined based on the multiple parameters. Thereafter, particles are outputted from the system when the logic condition is present. Accordingly, multiparameter high-speed measurements of a rare subpopulation of particles (e. g. biological cells) can be made amidst a larger population of particles with differing characteristics. When attached to a multiparameter flow cytometer/cell sorter and microcomputer, the system allows multiparameter analysis of cells at rates in excess of 100,000 cells/sec. This system can be an outboard module attached to a commercially available or home-built flow cytometer.

International Classification:

US Classification:

250358R

Abstract:

Method and apparatus for analyzing pulses from optical devices such as flow cytometers to generate indicators of particle dimensional attributes, such as size and shape, as well as orientations in a flow stream of non-spherical particles. Particles are conveyed through a beam of electromagnetic radiation and a photodetector responds to radiation resulting from interaction of the particle with the beam to output a resultant signal in the form of a pulse as a particle enters and passes through the beam. Pulse edge width between two threshold values, preferably established as constant fractions of peak pulse amplitude, is measured as an indication of a particle dimensional attribute.
