Descripción
Sumario:The cathodic evolution of hydrogen and its electrooxidation on platinum molten KHSO<sub>4</sub> have been studied over a wide range of temperature. The former reaction was mechanistically interpreted in a simple way by assuming that on platinum black the hydrogen discharge step is followed by the recombination of hydrogen atoms as the r.d.s. The cathodic reaction is inhibited by sulphide species formed at high cathodic current densities.
