Abstract

Air management of the polymer fuel cell system is a key issue to increase the performance and the efficiency. The air compressor is used as an important lateral device for the fuel cell system. By using of this system, input parameters into the fuel cell collection are determined and used in other subsystems. The final goal of this paper is to design the dynamic model for an air compressor of the fuel cell collection in the Matlab\ Simulink software. This action is for obtaining an accurate and continuous control on the input air parameters. In this model, by using of the static feed forward function, requested electrical current of the fuel cell is related to the air compressor model. In addition, input thermodynamic parameters of the air compressor have been assumed to set in the determined value. With the designed model, changes in the compressor parameters are intercepted. Investigated parameters are angular velocity, temperature, compressor power, mass flow rate, outlet air pressure and the compressor efficiency. Finally, the results of the dynamic model as well as the compressor map are fully validated based on the available results in the open literature. Therefore, the centrifugal compressor model is produced that can be added to polymer fuel cell collection as a lateral system. In addition, the results show that the model can predict the dynamic behavior of the compressor accurately and it can be used directly for any control purposes.
