1. An automated fuel processing system, comprising:
- a fuel processor adapted to receive a feed stream and produce hydrogen gas therefrom;
a feed assembly adapted to deliver the feed stream to the fuel processor; and
a control system including a sensor assembly adapted to monitor the value of at least one operating parameter of the fuel processing system and a controller in communication with the sensor assembly and adapted to receive inputs therefrom, wherein the controller includes a memory device that includes a plurality of stored subroutines, and further wherein the controller is further adapted to automatically execute one or more of the stored subroutines responsive at least in part to inputs from the sensor assembly to control the operation of the fuel processing system at least in part based on the inputs from the sensor assembly.
