Abstract

This paper introduces a fuel cell (FC) emulator based on experimentally validated dynamic solid oxide FC (SOFC) and proton exchange membrane FC (PEMFC) models for power electronics converter design and test, and fault diagnosis and mitigation. The FC emulation developed includes both the steady-state and transient responses of an FC. A Matlab/Simulink environment is used to implement the FC model, convert and compile it into a C-program and build into real-time control, which is finally programmed into a dSPACE and/or DSP controller for prototype testing and design and field testing. The output of the controller is sent to a linear power amplifier (power converter) that drives a power converter or a load. Experimental test was carried out to observe the steady-state and transient responses of the FC emulator. Both implementation methods show very good results when compared with the experimental data.
