Abstract: A locomotive is provided including a main deck extending along a longitudinal axis and supporting one or more prime movers configured to be powered at least partially by gaseous fuel; a first truck and a second truck axially spaced apart in the direction of the longitudinal axis, the first and second trucks supporting the main deck; and at least one fuel compartment integrated into the main deck along the longitudinal axis, the at least one fuel compartment comprising one or more supports configured to support loads from the main deck, and one or more storage wells adapted to store one or more storage tanks for storing the gaseous fuel.

Abstract: A system and method are disclosed for high temperature protection of combustor and other components by controlling the temperature of combustor gases in a hybrid fuel cell system combustor using a nozzle or plurality of nozzles to inject water or water vapor, downstream or directly into the combustor. A variable speed pump, actuated valve or other flow metering device regulates the supply of water to the nozzles and a steam generator. Flow regulation is effected by a control algorithm that reacts to combustor temperature, changes in the power production of the fuel cell system and/or other related system parameters.

Abstract: A system and method are disclosed for high temperature protection of combustor and other components by controlling the temperature of combustion chamber gases in a fuel cell system tail gas burner using a nozzle or plurality of nozzles to inject water or water vapor upstream, downstream or directly into the combustion chamber. A variable speed pump, actuated valve or other flow metering device regulates the supply of water or water vapor to the nozzles. For the case of water vapor, an evaporator is required between the pump and nozzles. Flow regulation is effected by a control algorithm that reacts to combustor temperature, changes in the power production of the fuel cell system and/or other related system parameters.

Abstract: A hybrid fuel cell-gas turbine system and method efficiently generates power using a combination of separate power generating components. The system includes a turbine system having an air compressor and a turbine, and a fuel cell. By-product waste heat from the fuel cell is used within the fuel cell to heat the cathode air.
