Title: Method for generating a gas which may be used for startup and shutdown of a fuel cell

Abstract

The present invention provides a method for generating a gas that may be used for startup and shutdown of a fuel cell. In a non-limiting embodiment, the method may include generating a nitrogen-rich stream; merging the nitrogen-rich stream with a hydrocarbon fuel stream into a feed mixture stream; and catalytically converting the feed mixture into a reducing gas.

Method for generating a gas which may be used for startup and shutdown of a fuel cell

Patent Scotto, Mark Vincent; Birmingham, Daniel P.; DeBellis, Crispin L.; ...

The present invention provides a method for generating a gas that may be used for startup and shutdown of a fuel cell. In a non-limiting embodiment, the method may include generating a nitrogen-rich stream; merging the nitrogen-rich stream with a hydrocarbon fuel stream into a feed mixture stream; and catalytically converting the feed mixture into a reducing gas.

Apparatus for generating a gas which may be used for startup and shutdown of a fuel cell

Patent Scotto, Mark Vincent; Birmingham, Daniel P.; DeBellis, Crispin L.; ...

The present invention provides a gas generator that may be used for startup and shutdown of a fuel cell. In one non-limiting embodiment, the gas generator may include a nitrogen generator structured to receive air, extract oxygen (O2) from the air and discharge the balance in the form of a nitrogen-rich gas; a merging chamber structured to receive a hydrocarbon fuel and the nitrogen-rich gas and to discharge a feed mixture containing both the hydrocarbon fuel and the nitrogen-rich gas; and a catalytic reactor structured to receive the feed mixture and to catalytically convert the feed mixture into a reducingmore » gas. « less

Cover and startup gas supply system for solid oxide fuel cell generator

Patent Singh, Prabhakar [Export, PA]; George, Raymond A [Pittsburgh, PA]

A cover and startup gas supply system for a solid oxide fuel cell power generator is disclosed. Hydrocarbon fuel, such as natural gas or diesel fuel, and oxygen-containing gas are supplied to a burner. Combustion gas exiting the burner is cooled prior to delivery to the solid oxide fuel cell. The system mixes the combusted hydrocarbon fuel constituents with hydrogen which is preferably stored in solid form to obtain a non-explosive gas mixture. The system may be used to provide both non-explosive cover gas and hydrogen-rich startup gas to the fuel cell.

Cooling/heating augmentation during turbine startup/shutdown using a seal positioned by thermal response of turbine parts and consequent relative movement thereof

Patent Schmidt, Mark Christopher [Niskayuna, NY]

In a turbine rotor, a thermal mismatch between various component parts of the rotor occurs particularly during transient operations such as shutdown and startup. A thermal medium flows past and heats or cools one part of the turbine which may have a deleterious thermal mismatch with another part. By passively controlling the flow of cooling medium past the one part in response to relative movement of thermally responsive parts of the turbine, the flow of thermal medium along the flow path can be regulated to increase or reduce the flow, thereby to regulate the temperature of the one part tomore » « less

Systems and methods for monitoring a power-generation module assembly after a power-generation module shutdown event

Patent Buenaventura, Don; Bowman, Doug

Embodiments are directed to providing a user interface (UI) that streamlines and simplifies the process of monitoring critical power-generation module (PGM) parameters after a PGM assembly is shutdown. The UI displays, in real-time, indicators corresponding to one or more post-shutdown PGM parameters. The UI provides indications of whether the post-shutdown PGM parameters meet post-shutdown criteria of the PGM assembly. When a post-shutdown PGM parameter does not meet the post-shutdown criteria, a user alert is provided to the user. A protocol may additionally be provided to the user. In some embodiments, the protocol may enable the user to return the PGMmore » « less
