Systems and methods for transitioning a fuel cell system between operating modes. The fuel cell system may be a SOFC system comprising Ni-containing anodes. The transitions may be from a shutdown mode to a hot standby mode, from a hot standby mode to a power ready hot standby mode, from a power ready hot standby mode to an operating mode, from an operating mode to a power ready hot standby mode, from a power ready hot standby mode to a hot standby mode, from a hot standby mode to a shutdown mode, and from an operating mode to a shutdown mode.

Reducing gas generators and methods for generating a reducing gas

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 (O) 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 reducing gas.

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

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

A multistage combustor is configured for starting a fuel cell system, and includes a partial oxidation (POX) burner having an inlet for receiving a flow of a fuel/oxidant mixture, the POX burner being configured to partially oxidize fuel in the fuel/oxidant mixture to yield a partially oxidized gas; a first output coupled to the fuel cell system and configured to provide a first amount of the partially oxidized gas as first output gas to a first fuel cell system component; a second burner coupled to the POX burner, the second burner being configured to receive a second amount of the partially oxidized gas from the POX burner and to oxidize at least some remaining fuel to yield a second output gas different from the first output gas; and a second output coupled to a second fuel cell system component and configured to provide the second output gas to the second fuel cell system component.
