Among other factors, EIS is an experimental technique that can be used to separate and quantify these sources of polarization. By applying physically-sound equivalent circuit models wherein physiochemical processes occurring within the fuel cell are represented by a network of resistors, capacitors and inductors, you can extract meaningful qualitative and quantitative information regarding the sources of impedance within the fuel cell. EIS is useful for research and development of new materials and electrode structures, as well as for product verification and quality assurance in manufacturing operations. This article provides a quick primer on EIS with an introduction to its application in fuel cell testing and research. Instrumentation and measurement basics During an impedance measurement, a frequency response analyzer FRA is used to impose a small amplitude AC signal to the fuel cell via the load. The AC voltage and current response of Figure1 the fuel cell is analyzed by the FRA to determine the resistive, capacitive and inductive behavior -the impedance - of the cell at that particular frequency. Response exhibited at different AC frequencies. When conducted over a Analyzer broad range of frequencies, impedance spectroscopy can be used to identify and quantify the impedance associated with Gen.

Gujarat, India - India StructId: 319287 Hide details Abstract: Impedance spectroscopy is a popular analytical tool in materials research and gives plenty of information after careful analysis. Experimentally obtained data can be analyzed by using a mathematical model based on possible physical theory that predicts theoretical impedance or a relatively empirical equivalent circuit. In the present review the complex impedance plots, i. Nyquist plots are analyzed by Z-view software and the values of grain and grain boundary resistances and capacitances are evaluated and the equivalent circuits are proposed for different materials. The results of pure and doped lead tartrate crystals, pure and amino acid doped ADP crystals and pure Hydroxyapatite nano-particles are reviewed.

It has found that grain and grain boundary effects are very sensitive to doping and it is reflected in Nyquist plots. From the results it is found that the impedance spectroscopy technique is a sensitive technique to detect impure or doped system.

Spectroscopie d'impédance electrochimique locale: caracterisation de la de lamination des peintures et de la corrosion des alliages Al-Cu. La seconde partie présente trois applications différentes dans lesquelles la SIEL apporte des informations déterminantes.

La première application est consacrée à l'étude du CPE constant phase element. Cet élément, bien que régulièrement utilisé dans l'interprétation des diagrammes d'impédance électrochimique, garde une signification physique vague. Les mesures de SIEL ont montré que le CPE pouvait être interprété comme une distribution locale de résistances et de capacités en 2 ou 3 dimensions. Les études suivantes se rapportent au domaine de la corrosion et de la protection des matériaux. La SIEL s'est avérée être une technique performante pour visualiser et mesurer la surface délaminée de manière non destructive.
