The electrochemical behavior of dissolved hydrogen (H2) was investigated at a Pt electrode in a high temperature LiOH–H3BO3solution. The diffusion current of the H2oxidation was proportional to the concentration of the dissolved H2as well as the reciprocal of the temperature. In the polarization curve, a potential region in which the oxidation current decreases despite an increase in the applied potential between the H2oxidation and the water oxidation regions was observed. This potential region was interpreted as being caused by the formation of a Pt oxide layer. Using the properties of the Cl−ion that reduces the growth rate of the Pt oxide layer, it was confirmed that there is a correlation between the Cl−ion concentration and the transient current of the H2oxidation. |
