Electrochemical impedance spectroscopy is a suitable and powerful diagnostic testing
method for fuel cells because it is non-destructive and provides useful information about fuel …

In this paper, equivalent electric circuit models of a commercial 1.2-kW proton exchange
membrane (PEM) fuel cell stack are proposed based on AC impedance studies. The PEM …

Water management is critical for PEMFCs, especially at system level. To study its impact on
the performance and obtain useful indicators for fault detection, two commercial stacks were …

In this work, extensive electrochemical impedance measurements have been conducted on
a 45 cm2 BASF Celtec P2100 high temperature PEM MEA. The fuel cell performance has …

In this paper, energy and exergy analyses for a 1.2 kWp Nexa PEM fuel cell unit in a solar-
based hydrogen production system is undertaken to investigate the performance of the …

This paper presents the parameter identification of an equivalent circuit-based proton-
exchange membrane fuel cell model. This model is represented by two electrical circuits, of …

Addition of an oxygen evolution reaction (OER) catalyst is a materials approach to mitigate
the impacts of potential reversal caused by fuel starvation. In this study Iridium oxide (IrO x) …

This work constitutes detailed EIS (Electrochemical Impedance Spectroscopy)
measurements on a PBI-based HT-PEM unit cell. By means of EIS the fuel cell is …
