Herbert C Healy, Matthew Kolodney, Alexander H Levy, John C Trocciola: Recovery of carbon dioxide from fuel cell exhaust. International Fuel Cells Corporation, William W Jones, June 14, 1988: US04751151 (47 worldwide citation)

A gaseous mixture of hydrogen and carbon dioxide is used as the fuel cell fuel or anode gas, and air is used as the oxidant or cathode gas in a nonalkaline fuel cell power plant. In feeding the fuel gas through the anode side of the fuel cell, hydrogen is removed during the electrochemical reaction ...

Ronald J Spiegel, Richard A Sederquist, John C Trocciola, Herbert C Healy, Roger R Lesieur, Gregory J Sandelli: Landfill gas treatment system. International Fuel Cells, William W Jones, September 19, 1995: US05451249 (38 worldwide citation)

The gas stream which emanates from landfills is treated to produce a purified gas which is essentially a hydrocarbon such as methane which can be used as the fuel source in a fuel cell power plant, or can be used in other power plants which use natural gas as a fuel. The landfill gas passes through ...

Herbert C Healy: Method for producing steam from the liquid in a moist gas stream. United Technologies Corporation, Stephen E Revis, June 8, 1982: US04333992 (24 worldwide citation)

To avoid using high quality heat to boil water condensed from a moist gas stream and to increase the overall thermal efficiency in a system requiring a supply of steam obtained by boiling water condensed from a moist gas stream, the condensing of the desired amount of water is done in a combined con ...

Douglas Gibbons Young, Herbert C Healy: System for providing assured power to a critical load. UTC Fuel Cells, Stephen A Schneeberger, June 13, 2006: US07061139 (21 worldwide citation)

A first AC power source comprising a power plant (18), and a second power source, typically grid (10), are normally connected via a high speed isolation switching means (19) to provide sufficient AC power to a critical load (14). The power plant (18) comprises a power generating means, e.g. a fuel c ...

John C Trocciola, Herbert C Healy, Roger R LeSieur, Ronald J Spiegel: Removal of hydrogen sulfide from anaerobic digester gas. International Fuel Cells, William W Jones, November 2, 1999: US05976373 (13 worldwide citation)

The effluent gas stream from anaerobic waste water treatment digesters is treated to remove trace amounts of hydrogen sulfide and other contaminants. The chemical equation involved relies on the reaction of hydrogen sulfide with oxygen to form water plus elemental sulfur. The removal system includes ...

Douglas Gibbons Young, Herbert C Healy, Francis A Fragola, Ricky M Ross: System for providing assured power to a critical load. Stephen A Schneeberger, August 15, 2002: US20020109410-A1 (1 worldwide citation)

A power system (8) is provided for economically supplying uninterrupted electrical power to one or more critical loads (14). One or more fuel cell power plants (18) provide one substantially continuous source of power, and a utility grid (10) provides another source of power. The fuel cell power pla ...
