Description
Figure 1: ORR activity of Pt/C catalyst modified with [BMIM][beti]. A) Mass specific ORR activity, depending on the amount of IL obtained in RDE measurements at room temperature in oxygen saturated 0.1 M HClO4 and 1600 rpm at a catalyst loading of 20 µgPt cm-2. B) ORR potentials at different current densities depending on the amount of IL obtained in GDE measurements at room temperature in oxygen atmosphere in 2 M HClO4 at a catalyst loading of 100 µgPt cm-2. C) ORR polarization curve of unmodified Pt/C and Pt/C modified with 15 wt.% of IL measured in a MEA at 80 °C and 100 %RH in oxygen atmosphere (1 atm) at a catalyst loading of 100 µgPt cm-2.
