    Abstract: An apparatus for producing hydrogen having compressor motor speed control. The apparatus includes a hydrogen generator for producing a product comprising hydrogen and a compression unit for compressing the product. The hydrogen generator can include a fuel processor having an oxidizer and a reformer. The compression unit has an induction motor and means for regulating the speed of the motor. The means for regulating the speed of the motor can include a variable frequency drive or soft start device having a plurality of switches and an adjustable ramp timer. A downstream unit including one or more of a purification unit, a second compression unit, and a storage unit is disposed downstream of the compression unit. A method for producing hydrogen is provided that includes generating a product comprising hydrogen in a hydrogen generator, compressing the product in a compression unit having an induction motor and regulating the speed of the motor in response to transient operations of the hydrogen generator.

    Abstract: A catalytic reformer assembly and methods of operation, including fast start-up, are provided. The reformer assembly includes an electrically-conductive metallic vaporizer having a very high surface area. At start-up of the reformer, electric current is passed through the vaporizer to heat the material by resistance heating, providing a high-temperature, high-surface area environment for fuel vaporization. Preferably, the electric current is started a few seconds before starting fuel flow. The fuel is sprayed either onto or through the heated vaporizer, preferably before the fuel is mixed with incoming air to minimize convective cooling by the air and to reduce the pressure drop in the fuel flow. As the reformer warms up, energy from the reforming process heats the vaporizer via radiation and/or conduction such that electric power is needed only during the start-up phase. A control circuit regulates the amount and duration of electric power supplied to the vaporizer.
