Hello, inductance L is used to indicate adsorbed species on electrodes. Lstray may refer to a particular species that gets adsorbed but is not expected to get adsorbed, suhc as stray H atoms. You have to related the element to your fuel cell chemistry.
Yes, if you have connected the working electrode terminal to anode in battery, then first arc RC will mean SEI. You will have to define the terms and their meaning as per their physical significance. If you connect working electrode terminal to cathode during EIS testing, then you will have to look at the reactions occurring at cathode as the EIS will indicate changes in cathode. Hence, correct connections is crucial in battery systems.
We cannot find it using impedance directly. We can use charge transfer resistance trend from impedance and compare it to trend in polarisation resistance Rp obtained from Tafel plot.
Thank you. I understood well Dr. Shyama. Keep growing!!!!!
Great to know! Thank you for your feedback!
What is Lstray in circuit ? What is the use of that or could u please explain fuel cell fitting in EIS

Well explained Dr Shyama, Thank you
Thanks a ton!
Where SEI plays here , as I see first arc is referred as RC for SEI which is like film on electrode but it is produced and it grows as cell ages ryt?
Bye the way good intuitive explaining for none electro chemistry background

Film on electrode w.r.t to cathode , as because SEI forms only on anode
How can we find corrosion rate from impedence in gamry software??

Very “tricky”, great explanation!
Glad you liked it! Thank you!
amazing . Thank you.
Glad you liked it!
Thank you dear maam
My pleasure! Do let me know if you need any other explanantion and share the video with your acquaintances!
