文摘
The proton activity of the Nafion membrane was estimated from the potential difference between a normal hydrogen electrode (NHE) in 0.5?mol?dm? H2SO4 and a dynamic hydrogen electrode (DHE) constructed on a Nafion 117 membrane. The potential difference between the DHE and the NHE was directly measured at the same temperature in a box chamber filled with N2 gas. As a result, the potential difference of E NHE??-em class="a-plus-plus">E DHE changes from 0.006 to ?.024?V with the increasing temperature from 289 to 313?K; however, the potential difference remains at around ?.024?V when the temperature is between 313 and 343?K. Based on these data in combination with the Nernst equation, the proton activity of the Nafion 117 membrane at 289?K is estimated to be 0.8, which increases up to ca. 2.4 with the increasing temperature.
