Abstract:
1. Electrolytic cell for electrodialysis of salt solutions delimited by an anodic semi-shell and a cathodic semi-shell, comprising: one anodic chamber delimited by said anodic semi-shell and by a gas-diffusion anode fed with a hydrogen-containing fuel gas; at least one intermediate chamber fed with a process electrolyte consisting of a solution containing an acid and/or a salt, said at least one intermediate chamber delimited by said gas-diffusion anode and by an ion-exchange membrane; one cathodic chamber delimited by said ion-exchange membrane and said cathodic semi-shell, containing a gas-diffusion cathode fed with a oxygen-containing oxidant gas; the anodic semi-shell and the cathodic semi-shell being either mutually short-circuited or connected through a current rectifier with the positive pole connected to the anodic semi-shell and the negative pole connected to the cathodic semi-shell.
