Electrode Degradation in PEMFCs as Studied in Model Systems and PEMFC Testing [PDF]

ECS Transactions, 2009
In order to meet the durability criteria for PEM Fuel Cells, needed for their successful application in transport, more insight is needed into which conditions have a detrimental effect on the long term performance, and which materials improvements are needed to make PEMFC better suited to withstand some of these conditions that are unavoidable in ...

Nonintrusive Diagnosis of a PEMFC [PDF]

IEEE Transactions on Magnetics, 2015
Many reasons may cause malfunction of a proton exchange membrane fuel cell (FC) stack. Moreover, a single defect cell can affect the whole stack functioning; therefore, the localization of this cell is crucial as well as identifying the root causes for such malfunctioning.

Real-Time Monitoring of HT-PEMFC [PDF]

Membranes, 2022
During the electrochemical reaction of a high temperature proton exchange membrane fuel cell (HT-PEMFC), (in this paper HT-PEMFC means operating in the range of 120 to 200 °C) the inhomogeneity of temperature, flow rate, and pressure in the interior is likely to cause the reduction of ion conductivity or thermal stability weight loss of proton exchange

PEMFC Fault Diagnosis, Modeling, and Mitigation [PDF]

IEEE Transactions on Industry Applications, 2008
This paper introduces fault diagnosis and separation, mitigation, and modeling of a proton exchange membrane fuel cell (PEMFC). Experimental tests of a single PEMFC were performed during this study. Flooding and drying faults were implemented to be detected from the cell voltage and impedance response of the cell.

Simulation of PEMFC performance

Journal of Renewable Energies, 2023
Throughout literature, there are two approaches to estimate fuel cells (FC) performance, by the evaluation of polarization curve. One includes, physical modelling of heat and mass transfer with electrochemical phenomena; the second is based on semiempirical equation used in order to analysis the effect of different physical perturbation on the ...

Robust PID control of a PEMFC system

2010 IEEE International Conference on Control Applications, 2010
This paper proposes robust proportional -integral-derivative (PID) control for a proton exchange membrane fuel cell (PEMFC) system. We model a PEMFC as a multivariable system, and apply identification techniques to obtain the system's transfer function matrices, where system variations and disturbances are regarded as system uncertainties.
