Abstract
Presents the steady state and transient model of a natural gas fuel processing system of a solid oxide fuel cell (SOFC) hybrid system.  The model is validated with data obtained through the use of an actual plant.
The Thermochemical Power Group of the University of Genoa, Italy, developed the model using the in-house tool TRANSEO working in the Matlab/Simulink environment.  The plant used for validation was designed and built by Rolls-Royce Fuel Cell Systems Limited (RRFCS) to feed a 250 kWe SOFC hybrid system with a methane stream undergoing requirements about composition, pressure, and temperature. Authors detail the fuel processing system.  Particular emphasis is placed on the selective catalytic sulphur oxidation (SCSO) and the catalytic partial oxidation (CPOx) subsystems.
