I want to compare the HER and OER results of metal strips that I have prepared now in elecrtochemical workstation I am using those strips of 0.5 cm*0.5 cm as working electrode. Now in order to compare it with standard commercial Pt/C should I deposit Pt/C slurry on glassy carbon electrode and then do analysis to compare the results or there is some alternative method to prepare commercial Pt/C like a those of square metal strips I am using?
If I have to use GC then should the area of GC and metal strips be equal or not ?
