Paper Abstract

Depending on the electrode material and on the cations, the electrolysis of water starts at significantly higher voltages than the standard potential of the water electrolysis cell, which is 1.23V. We present the simple methodic of determining the "safe" voltage of aqueous IPMCs below what there is no water electrolysis, with the corresponding quantitative data. Higher voltages applied to IPMC cause irreversible formation of platinum oxides and absorption of hydrogen on the platinum electrodes that can change the mechanism of water electrolysis and decrease the minim required voltage of water electrolysis even below the 1.23V.
