The invention relates to a novel ruthenium sulphide catalyst and to gas diffusion electrodes incorporating the same for reduction of oxygen in industrial electrolysers. The catalyst is highly resistant towards corrosion, thus resulting particularly suitable for use in oxygen-depolarised aqueous hydrochloric acid electrolysis.
L'invention concerne un nouveau catalyseur ruthenium sulphide et des électrodes de diffusion gazeuse contenant le catalyseur de réduction d'oxygène dans des électrolyseurs industriels. Ce catalyseur est hautement résistant à la corrosion et donc particulièrement adapté à une utilisation dans une électrolyse d'acide chlorhydrique aqueuse dépolarisée en présence d'oxygène.
