Appl. No.:

10/458706

Inventors:

Albert P. Grasso - Vernon CT, US
Bryan F. Dufner - West Hartford CT, US
Jay C. Files - Windsor CT, US

Assignee:

UTC Fuel Cells, LLC - South Windsor CT

International Classification:

H01M008/04
H01M008/06

US Classification:

429 17, 422171, 422172, 422177, 422189, 422190, 42324301, 429 19, 429 20, 429 34

Abstract:

Method and apparatus are provided for removing contaminants from a hydrogen processor feed stream, as in a fuel cell power plant (). Inlet oxidant (), typically air, required by a catalytic hydrogen processor () in a fuel processor () for a fuel cell stack assembly () in the power plant (), may contain contaminants such as SOand the like. A cleansing arrangement, which includes an accumulator/degasifier () acting as a scrubber, and possibly also a water transfer device (), receives the inlet oxidant and provides the desired cleansing of contaminants. Water in the water transfer device and in the accumulator/degasifier serves to dissolve the water-soluble contaminants and cleanse them from the oxidant stream. The cleansed oxidant stream (′) is then delivered to the hydrogen processor and to the fuel cell assembly, with minimal inclusion of detrimental contaminants such as sulfur.

Inventors:

Michael Morsches - Trumbull CT, US
David Kulczyk - Torrington CT, US
Jay Files - Windsor CT, US

International Classification:

F16D003/52
F16D003/64
F16D003/76

US Classification:

464/075000

Abstract:

A housing has a longitudinally extending aperture and at least one internal, longitudinally extending groove. At least one longitudinally extending blade is mountable on the shaft and positioned within the housing such that the blade extends radially outwardly into the longitudinal groove of the housing. A cross pin extends radially through the longitudinally extending aperture of the housing for engagement with the shaft, and a resilient material is positioned between the housing and the blade, and between the cross pin and the housing, such that the blade will transmit torque to the housing with a desired radial, axial and torsional compliance.

International Classification:

B08B 9/032
B08B 9/04
F02B 77/04

Abstract:

A method is provided involving a gas turbine engine system. The method includes configuring a plug within a fluid passage in the gas turbine engine system, where the plug is between first and second portions of the fluid passage. Material is removed from an interior surface of the fluid passage in the first portion of the fluid passage to provide removed material, where the plug substantially prevents the removed material from entering the second portion of the fluid passage. The removed material is directed out of the fluid passage. The plug is removed from the fluid passage.
