Study of Dynamic Behavior for PEMFC Stack

The dynamic behavior of a stack through experiment was compared with the simulation results of a dynamic model by using MATLAB/SIMULINK® for instantaneous change of power demand. The system consists of a 150W commercial fuel cell stack, humidifier, MFC and controller. The model was established with four basic equations. Model coefficients were calculated from experimental data and literatures. Polarization curve and dynamic responses showed similar behavior for both experimental and simulation results.Copyright © 2005 by ASME
