Abstract
The results of impedance measurements on gold and nickel electrodes in molten carbonate at a temperature of 650{sup o}C under different gas compositions are presented. A corrosion mechanism of nickel is proposed on the basis of these measurements. For the nickel metal six regions are investigated: the cathodic carbonate decomposition, the hydrogen oxidation at the electrode, the passivation of nickel, the dissolution of nickel through the passive layer, the passive state, the Ni{sup 2+}/Ni{sup 3+} oxidation and the anodic decomposition of carbonate. First, measurements were performed at a gold electrode to study the hydrogen oxidation mechanism under conditions without complicating factors as passivation, etc. Next, the hydrogen oxidation mechanism at the nickel electrode is described. 73 figs., 6 tabs., 1 appendix, 22 refs.
