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

化学测量表明,H2/O2 电池的开路电位(OCP)随组成酸碱的δpKa 的增大而增大,并经过一个最大值后随着δpKa 的进一步增大而逐渐下降。
