Dynamic Modeling of the Air Supply System for PEMFC Stack

Abstract:

The dynamic model of the air supply system for a proton exchange membrane fuel cell (PEMFC) stack is developed in this paper. The PEMFC cathode/anode, and air supply system including a compressor, a motor, and a supply manifold(SM) are modeled; the compressor performance map is identified based on a fuzzy neural network (FNN). The PEMFC air supply system is simulated by using Matlab environment. The simulation results show that the proposed models can effectively represent the dynamic characteristics of the system components, and lay the foundation for the control strategy design of the PEMFC air supply flow.
