Figure S5 LSV varying compliance voltage
MetadataShow full item record
Figure S5: CV curves recorded in ambient air with two Potentiostats with a differing compliance voltage of 10 V and 12 V, respectively. Measurements were carried out on GDEs with a Pt loading of 100 µg cm.2 and a catalyst-coated area of 0.5 cm2 in 2 M HClO4. shows that the Potentiostat with the higher compliance voltage of 12 V allows a higher maximum current to flow through the cell. An interesting feature when comparing the curves recorded with the different Potentiostats is that the maximum current in the measurement with the Potentiostat with the lower compliance voltage is given as a plateau, while the Potentiostat with higher compliance voltage is stopping to record current once the compliance voltage is reached.
