This collection of three Maple files aims to help PEM fuel cell developers to analyse their experimental data. Note: All the *.txt files below must be saved with the extension *.mw in order for Maple software could recognize them. The files have been tested with Maple 18 and Maple 2015. The most important information on variables and conditions can be found directly in every file.
Curve_Fitting.mw performs least--squares fitting of the PEMFC polarization curve. The details are described in the paper A.A.Kulikovsky. A Physically–Based Analytical Polarization Curve of a PEM Fuel Cell. Journal of The Electrochemical Society, 161 (2014) F263-F270. An author's pdf file is attached.
FittingImpedanceSpectrum.mw performs fitting of the experimental impedance spectrum of a PEMFC. The algorithm neglects the impedance of the gas--diffusion layer (GDL). The details are given in the paper A.A.Kulikovsky. Exact low–current analytical solution for impedance of the cathode catalyst layer in a PEM fuel cell. Electrochimica Acta, 147 (2014) 773–777. An author's pdf is attached.
FittingPEMFCspectra.mw is a more general algorithm for PEMFC impedance spectra fitting. It includes impedance of the GDL. Details are written in A.A.Kulikovsky. One-Dimensional Impedance of the Cathode Side of a PEM Fuel Cell: Exact Analytical Solution. Journal of The Electrochemical Society, 162 (2015) F217-F222 (pdf is attached). Note Errata; a pdf file is attached.
