NOVELTY - A hydrogen generator comprises a fuel processor for producing reformate from fuel (preferably hydrocarbon), a hydrogen purifier for generating purified hydrogen gas stream from reformate, a compressor for providing the reformate from the fuel processor to the hydrogen purifier at desired pressure, and a control system for integrating and controlling the operation of fuel processor, hydrogen purifier, and compressor.    USE - For generating hydrogen useful in fuel cells.    ADVANTAGE - The inventive hydrogen generator incorporates a control system that allows rapid and easy expansion of process control system and facilitates seamless plug-ins of new subsystems. Different types of instruments can be added, removed, or replaced without affecting the control system and without requiring a lot of programming.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (A) a control system for use with a purified hydrogen generator, comprising a computing device, a bus system, a storage communicating with the computing device over the bus system, and a software application residing on the storage;    (B) a method of controlling the operation of a purified hydrogen generator by controlling the operation of a hydrogen generator, controlling the operation of a hydrogen purifier, and synchronizing the controlled operation of hydrogen generator with the controlled operation of hydrogen purifier by jointly controlling the operation of both the hydrogen generator and the hydrogen purifier;    (C) a program storage medium encoded with instructions that, when executed by a computing device, perform a method for controlling the operation of a purified hydrogen generator; and    (D) a computing system comprising a computing device, a bus system, a storage communicating with the computing device over the bus system, and an application residing on the storage and capable of performing a method for controlling the operation of a purified hydrogen generator.
