Abstract
This study investigates the effects of operating
parameters of different current density, temperature and pressure on
the performance of a proton exchange membrane (PEM) water
electrolysis stack. A 7-cell PEM water electrolysis stack was
assembled and tested under different operation modules. The voltage
change and polarization curves under different test conditions, namely
current density, temperature and pressure, were recorded. Results
show that higher temperature has positive effect on overall stack
performance, where temperature of 80 ℃ improved the cell
performance greatly. However, the cathode pressure and current
density has little effect on stack performance.
