The selection of the key components of proton exchange membrane fuel cell (PEMFC)
crucially impacts the performance. This work developed a model of the fuel cell
system model to simulate the power consumption of component and system and the
temperature dynamic response of stack in real systems. A PEMFC simulation model
was developed based on AMESim, encompassing the air supply subsystem, hydrogen
supply subsystem, and the hydrothermal management subsystem. The parameters for
the flow and pressure of hydrogen, air, and water were established based on the
operational requirements to ensure efficient stack performance. Furthermore, a
PID control model was employed to regulate the flow and pressure parameters of
hydrogen, air, and water, in accordance with the operational requirements, to
ensure optimal PEMFC system performance.The purpose of this study is to predict
the power consumption of the key components and the overall system, as well as
to analyze the compliance with fuel supply, oxidant delivery, and reactor
cooling requirements, thereby validating the suitability of the selected key
components.For a 40 kW PEMFC system, the suitability of the component selection
was validated by comparing the simulation outcomes against empirical data,
yielding a mean absolute percentage error (MAPE) below 0.64%. This indicates
that the model can be used to predict the output performance of the fuel cell
under different conditions and has significant instructive value. The main
contents of the paper are as follows:
A
PEMFC simulation model encompassing air, hydrogen supply, and
thermal management systems has been
created.
The operational parameters of
the fuel cell system, including hydrogen gas, air, and water flow
rates and pressures, are precisely controlled by the PID control
system.
For a 40 kW fuel cell system,
the suitability of component selection was validated by comparing
simulation outcomes against empirical data, yielding a MAPE below
0.64%.
