Thank you Sundararajan.T.

u can do the AC Impedance analysis at NML-CSIR, Taramani.

Actually Im talking about Solid Oxide Fuel cell so there is no problem of leakage. It is a solid material with anode, cathode and solid oxide electrolyte. The material must be kept in a tubular furnace and heated I suppose. So a special arrangement is needed. Kindly e-mail me, so that we might discuss further on this. My mail is divinah@gmail.com. I'll send you related references and graph for the work.

First of all i have a potentiostat where EIS can be done. But there are 2 problems :
1. I don't know how you'll maintain the temperature, as what your saying.
2. You'll need a fuel cell, with all electrodes, catalysts and membranes affixed without any leakage.

I think it would be better if you can arrange for two identical fuel cell sets, where variations can be done on temp and membranes.

I-V and I-P characteristics can be done but you'll have to ensure it, that whatever comes whether its right or not.

Ya.. If you are interested let us proceed..

May be i can help or rather i should say we together can sort it out.. what sort of instruments u need for this..?. I think a potentiostat is well enough...isn't it.?

I need electrochemical impedence ie, arrhenius plots and complex impedance plots for materials prepared for application in fuel cell at temperature from 400 to 800 degree C. It would be also good if i get I-V and I-P characteristics.

what sort of impedance characterization you need?. Is it for something related to cell impedance. If so may be i can help you.
