Polymer electrolyte membrane fuel cells (PEMFCs) utilized for portable applications must supply uninterruptible and reliable power with constant voltage. The PEMFC is, however, limited for transient peak power demand that confines it for being applied in a high power system, especially using for transportations. To overcome this issue, PEMFC hybridization with supercapacitor (SC) based on power balance strategy will support the PEMFC system in desired operating conditions, positively affecting on an increase in PEMFC performance. The aim of this work is to observe performance characteristics and voltage degradation of a PEMFC/SC hybrid system compared with a traditional PEMFC system. To achieve this purpose, a quasi-static profile was created to separately investigate the influences of stationary conditions, load variations, and start-stop conditions on the voltage degradation of a PEMFC/SC single cell. Polarization curves, hysteresis loops, voltage degradation rates were determined. The cell performance was also analyzed using electrochemistry impedance spectroscopy (EIS).
