Abstract

L'invention concerne un procédé de production d'une électrode à diffusion de gaz destinée notamment à l'électrolyse d'une solution aqueuse de gaz chlorhydrique. Dans une première étape, a) une dispersion d'un catalyseur composée d'un métal noble et d'un isomère conducteur de protons dans un solvant organique est vaporisée sur un support électroconducteur éventuellement doté d'une matière de revêtement contenant un mélange noir d'acétylène-polytétrafluoroéthylène. Dans une deuxième étape, b) le solvant organique est supprimé.
