ABSTRACT: Proton exchange membrane fuel cell has advantages of high energy
conversion efficiency, high reliability, no pollution, low operating
temperature and rapid start-up. It has become an ideal method of hydrogen
energy utilization and is also ideally suited to be used as the main source of
energy for automobiles. Currently, it constitutes a research hot spot in the
field of new energy vehicles. Based on the working mechanism of proton exchange
membrane fuel cells and empirical models, a terminal voltage dynamic model, an
open circuit voltage model and three voltage loss models are established.
Matlab/Simulink software is utilized to simulate the model and perform analyses
in response to the impact of operating temperature and pressure on its
performance. To enhance the efficiency of the proton exchange membrane fuel
cell, the operating temperature should be increased in the medium and low
current density zones and the operating pressure should be increased in the
high current density zone.
