摘要：

A fuel cell operating without humidification and driven by hydrogen transfer via fluorohydrogenate anions, (HF)(n)F-, has been constructed using a room-temperature ionic liquid (molten salt), 1-ethyl-3-methylimidazolium fluorohydrogenates, EMIm(HF)(n)F. The open-circuit voltage was similar to 1.1 V under the flow of hydrogen and oxygen gas at 298 K. Polarization behaviors of the H-2 anode and O-2 cathode in EMIm(HF)(2.3)F revealed satisfactory performance as a fuel cell electrolyte. EMIm(HF)(1.3)F, which is thermally more stable than EMIm(HF)(2.3)F and does not liberate HF even at 373 K, exhibits significantly improved polarization behavior by the elevation of the operation temperature.
