I ran the single cell PEM fuel cell (Air-H). I employed stainless steel (uncoated) bipolarplate (BPP). basically, the conductivity is less than normal metal BPP. The galvanostat EIS test was run on this fuel cell. finally I saw the results like the attached image. the 3 EIS tests was run in AC 1A, 0.1 A and 0.01 A. the style of all are the same. Also, I ran EIS test with gold coated BPP and the result was normal (2 semi circles). I am sure about the connection and setup of test and fuel cell.
Which stainless steel are you using as BPP? Did you calibrate both steel and gold experiments?
Dear Matheus A. Tunes I used stainless steel 316. Which calibration do I use for BPP?
Dear Felipe Silva
I run a PEM FC. I could not understand your mean of "solution".
I test the BPP in fuel cell at 80 C.
Dear,
the test was performed in a prototype that simulated real operational conditions?
