| Summary: | In this paper, a mathematical model is developed
to simulate the transient phenomena in a polymer
electrolyte membrane fuel cell (PEMFC) system.
Large transient changes are expected for practical
application such as transportation vehicles due to
acceleration and deceleration. Simple models are
usually unable to capture these transient
dynamics. For control purposes, a fuel cell model
must include the dynamics of flow and pressure in
the anode and cathode channels and mass/heat
transfer transients. The proposed model can
predict the transient response of cell voltage,
temperature of the cell, hydrogen/oxygen out flow
rates and cathode and anode channel pressures
under sudden change in load current. It is
implemented in SIMULINK environment. The
model is tested by simulating a transportation-size
fuel cell with 85 kW maximum power output.
Results for maximum power and multi-step input
current that simulate start up-shut down cycle are
shown. The predicted power, pressure and
temperature are matching the published data for
the fuel cell. The model will be very useful for the
optimal design and real-time control of PEM fuel
cell systems in practical automotive or stationary
applications. |
