Abstract

When coupled to different applications, a polymer electrolyte fuel cell (PEFC) work at a different operating temperature. In this study, the internal resistance of a PEFC is evaluated by using Electrochemical Impedance Spectroscopy (EIS) at moderate low current density, i.e., 0.5 A/cm2, in the range of 40 – 80°C. The evaluation is carried out considering frequencies between 10kHz and 0.1Hz. An equivalent Randle circuit model is considered and the Nyquist and Bode diagram were obtained. Results show that the ohmic resistance and charge transport at low frequencies increase when the operating temperature is low, while the double layer capacitance increase at high temperatures.
