Experimental characterization of PEM fuel cells by micro-models for the prediction of on-site performance
2009
This paper presents the results of an experimental analysis performed on a miniaturized, 6 We Proton Exchange Membrane Fuel Cell (PEMFC) system, integrated with on-site hydrogen production by electrolysis; in particular, the effects of environmental parameters such as the external temperature and the humidity on the performance of fuel cells are investigated. PEMFC systems are zero-emissions power technologies when they are fed with pure hydrogen (at concentration higher than 97%); also, being the only results of system operation the produced electricity and some pure water, when produced by renewable sources hydrogen can be considered an attractive alternative to fossil fuels and may concu…
Design and Development of a Labview Application for the Measurement of the Complex Impedance of a Fuel Cell in Real Time
2014
International audience; To optimize the performance of fuel cells and to deepen the knowledge of their behavior, it is necessary to make measurements in real time. To run such a measure, it is necessary to use specific software and hardware tools to instrumentation fuel cells. In this context, we presented the steps of designing and developing an application for the measurement of the complex impedance by electrochemical impedance spectroscopy method (EIS) using LabVIEW® software. The experimental results are obtained using a Ballard Nexa® PEM fuel cell, an electronic load produced in our laboratory and application developed by the LabVIEW® software.
ADAPTION OF MULTI-PHYSICS PEM FUEL CELL MODEL USING SENSITIVITY ANALYSIS
2014
This paper presents the adaption of an existing multiphysics 1D fuel cell model to an existing PEM fuel cell system. The input parameters of the model are separated into system properties, linked to physical values, and running conditions. On the 40 system properties required, a sensitivity analysis was applied in order to identify that only four membrane properties have the most influence on the stack voltage. These parameter values were identified by optimization. The prediction accuracy with the new parameter values decreased to 1.48%.
Methanol fuel processor and PEM fuel cell modeling for mobile application
2010
International audience; The use of hydrocarbon fed fuel cell systems including a fuel processor can be an entry market for this emerging technology avoiding the problem of hydrogen infrastructure. This article presents a 1 kW low temperature PEM fuel cell system with fuel processor, the system is fueled by a mixture of methanol and water that is converted into hydrogen rich gas using a steam reformer. A complete system model including a fluidic fuel processor model containing evaporation, steam reformer, hydrogen filter, combustion, as well as a multi-domain fuel cell model is introduced. Experiments are performed with an IDATECH FCS1200™ fuel cell system. The results of modeling and experi…
