Abstract: Experiments are one of the most direct and effective method for research on high temperature
proton exchange membrane fuel cell (HT-PEMFC). An experimental platform was developed based on LabView
for HT-PEMFC to acquire experimental data of valuable parameters such as the temperature, pressure, mass
flow rate, and gas stoichiometry. The platform has control strategies for the parameters of the mass flow rate,
time and step length, which are significant for the use of PEMFC vehicles. By using the platform, polarization
curves and voltage losses were measured for both one-piece HT-PEMFCs and 1 kW HT-PEMFC stacks,
while contrast experiments were completed using different mass flow rate control strategies to improve the
performances of HT-PEMFC in the steady or dynamic process. The results are significant for further research
on HT-PEMFCs.
