SOFC Modelling and Parameter Identification by Means of Impedance Spectroscopy

Download or read book SOFC Modelling and Parameter Identification by Means of Impedance Spectroscopy written by André Leonide and published by KIT Scientific Publishing. This book was released on 2010 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high resolution electrochemical impedance spectroscopy study on anode supported single cells (ASC) is presented. The cells were characterised over a broad range of operating conditions, including different temperatures, current densities and various cathode and anode gas compositions.The analysis of the distribution of relaxation times combined with the numeric accuracy of a CNLS fit enabled the identification of five different processes contributing to the total polarisation loss of an ASC.
