The design of fuel gas processors supplying fuel cell drive systems with hydrogen strongly influences the efficiency and dynamics of the system. The main object of the work described below is to develop a fuel gas processor design promising acceptable response times in addition to high values of system efficiency and to determine an adequate start-up procedure. For that purpose a dynamic model of each relevant component of a fuel gas processor was developed and imported into a commercial software package for control design (Matlab/Simulink) in the form of software modules. The fuel gas processor model is set up by graphically linking the several modules together according to the particular system flow sheet. A particular design for a diesel fuel-reforming system worked out by means of steady-state analysis and a start-up concept were studied concerning the system response to changes of load and during start-up.
