Simulation Code for Gasoline Driven Fuel Cell Cars

Abstract

A simulation model of a car driven by a gasoline based fuel cell system was generated with Matlab/SIMULINK. The model of the vehicle represents a common compact class passenger car equipped with an electric power train, fuel cell system and with and without an additional battery. For the fuel cell system two variants have been implemented, a PEMFC and a high temperature SOFC system. Both models consist of an on‐board gasoline reformer, stack and auxiliary components such as evaporator, catalytic burner, fuel pump, fans and control unit with additional FC‐type specific components such as air preheater or CO‐shifter. The simulation model allows the comparison of the two FC systems in different automotive traction concepts (fuel cell vehicle, hybrid car) varying all important parameters such as driving cycle or fuel cell nominal power. In this paper the simulation model is described and first simulation results are given.
