Research on the performance of an Ag/AgCl solid reference electrode

The performance of the silver/chlorinated silver (Ag/AgCl) solid reference electrode was studied in the paper. The effects of the electrode's immersion time, the ways of making chlorinated silver (AgCl) powder, and the relative seawater flow velocity on the potential stability of the electrode were investigated by experiment. It was found that the potential of the electrode made by solid phase powder was stable in immersion, with the potential fluctuation of 2mV. Furthermore, it showed that the relative flow velocity of seawater had no obvious effect on the electrode potential under 3.6m/s, which could satisfy the engineering need and this solid electrode could be used as the reference electrode for underwater cathode protection.
