“…Figure 4 shows in-situ SNIFT-IR spectra for dema-FSI, dema-TFSI, and dema-BETI, obtained by 0.1 V steps of electrode potential from 1.2 V to 0.6 V vs. RHE. All the SNIFT-IR spectra for dema-FSI had the downward peaks at 1180 cm -1 and 1382 cm -1 , which corresponded to the vibrations of -SO 2 -N group (14)(15)(16). This result suggests that FSIgradually desorbs from the electrode surface as the electrode potential becomes negative.…”

Synthesis of New Protic Ionic Liquids for Fuel Cells on the Basis of In Situ FT-IR Measurements

et al. 2010

A series of protic ionic liquids (ILs) were synthesized from N,N-diethylmethylamine (dema) and three kinds of imides having different fluoroalkyl chain lengths (H-N(SO2(CF2)nF)2, n = 0~2) as electrolytes for fuel cells. The effect of anion structure on the oxygen reduction reaction (ORR) activity of Pt electrode was investigated in detail using the prepared ILs. As increasing n of imide-anion, the ORR current was increased. The onset potential for ORR was also shifted towards the positive side as extending the fluoroalkyl chain of imide-anion. This potential shift was clearly revealed by in-situ FT-IR measurement to relate the anion adsorbability on the Pt electrode, depending on the fluoroalkyl chain length of imide structure.
