抄録

The oxygen reduction reaction (ORR) on Pt in proton conductive room temperature molten salts (RTMSs) at 140℃ has been investigated for application in intermediate temperature (from 100 to 200℃) fuel cells. The ORR current was observed on Pt in neutralized RTMSs and acid-added RTMSs under an oxygen atmosphere. The order of the potential at the ORR current of -10^-2 mA cm^-2 was a mixture of trifluoromethanesulfonic acid and 1-ethyl-3-methylimidazolium triflate > a mixture of trifluoromethanesulfonic acid and 2-ethylimidazolium triflate > 85% phosphoric acid > 2-ethylimidazolium triflate > 2-ethylimidazolium tetrafluoroborate. The 1-ethyl-3-methylimidazolium cation would be more effective for the ORR on Pt than the 2-ethylimidazolium cation. The acid-added RTMSs will be better than the neutral one, concerning the ORR.
