Electrochemical properties of protic ionic liquids: correlation between open circuit potential for H2/O2 cells under non-humidified conditions and ΔpKa

Author affiliations

Abstract

Electrochemical measurements for a series of protic ionic liquids revealed that open circuit potential (OCP) for H2/O2 cells increases with increasing ΔpKa of the constituent acid and base and passes through a maximum to gradually fall for further increase in the ΔpKa, which indicates the reliance of the electrochemical activity on the persistence of non-ionic species and on the meagre proton activity due to strong N–H bonds.
