Hydrogen generation assemblies and methods are disclosed. In one embodiment, the method includes receiving a feed stream in a fuel processing assembly, and heating, via one or more burners, a hydrogen generating region of the fuel processing assembly to at least a minimum hydrogen-producing temperature. The method additionally includes generating an output stream in the heated hydrogen generating region of the fuel processing assembly from the received feed stream, and generating a product hydrogen stream and a byproduct stream in a purification region of the fuel processing assembly from the output stream. The method further includes separating at least a portion of the carbon dioxide gas from the byproduct stream to generate a fuel stream having a carbon dioxide concentration less than the byproduct stream, and feeding the fuel stream to the one or more burners.

An ejector receives steam at a primary inlet and natural gas at a secondary inlet. A computer responds to a signal indicating current in the load of a fuel cell as well as a signal indicating temperature of a steam reformer to move a linear actuator to control a needle that adjusts the size of the steam orifice. Reformate is fed to a separator scrubber which cools the reformate to its dew point indicated by a sensor. From that, a controller generates the fuel/carbon ratio for display and to bias a signal on a line regulating the amount of steam passing through an ejector to the inlet of the reformer. Alternatively, the reformate may be cooled to its dew point by a controllable heat exchanger in response to pressure and temperature signals.
