I greatly appreciate if anyone can share his/her experience on running EIS and CV test for a biocathode MEC. In-situ tests inside the complete cell can be applied, ifso how is the platform for running the test. Is it supposed to be run in OCV status like MFC , or do we have to apply the extra voltage over the external resistance during the tests?
Deeply appreciated
Interesting question. Sharma et al. 2015 seems to measure electrochemical parameters while the cell is running it as a biocathode not as a biocathode in an MEC. Aluenta et al. 2011 also performed cyclic voltametry on a lone biocathode. However, since you're testing it for hydrogen evolution, you may need the whole MEC. Since hydrogen evolution is not spontaneous, you need the voltage bias. Otherwise hydrogen may not be produced and the biocathode could not be tested.

Thanks so much Prof for your great advice. I will read your suggested papers. actually I read published papers on biocathode MEC, but the matter was not elaborated. deeply appreciated and Regards.
