Description
Figure S8: A) Influence of the position of the counter electrode on EIS curves recorded with the Pt wire CE as working electrode and the GDE as counter electrode @OCV. B) Influence of the position of the counter electrode on EIS curves recorded with the GDE as working electrode @-250 mA cm-2geo in oxygen atmosphere. C) iR drop between RE and GDE determined out of the EIS spectra shown in C).
