Figure S2 ORR IL modified PtC GDE + MEA in synthetic air
Description
Figure S2: ORR activity of Pt/C catalyst modified with [BMIM][beti] in synthetic air. A) ORR polarization curves obtained in GDE measurements at room temperature in synthetic air in 2 M HClO4 at a catalyst loading of 100 µgPt cm-2. B) ORR potentials at different current densities depending on the amount of IL obtained in GDE measurements. 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 synthetic air (1 atm) at a catalyst loading of 100 µgPt cm-2.
