Abstract: A device for cathodic protection against corrosion of at least one metal structure in contact with an electrolytic medium comprising a sedimentary soil, the protective device dispensing with the need for a sacrificial metal and means for connection to an electrical distribution network and including at least two microbial anode systems including microorganisms and an electrode configured to be in contact with the microorganisms and the electrolytic medium, the microorganisms having the ability to supply electrons to the electrode by degradation of oxidizable ambient resources according to oxidation-reduction reactions, the electrode of each microbial anode system being configured to be buried at least partially in the sedimentary soil of the electrolytic medium and the free electrochemical potential of the microbial anode system is lower than the free electrochemical potential of the metal of the metal structure to be protected.

Abstract: A bioelectrochemical reactor (1) has an anode chamber (11) having at least two bioanodes (12, 13), and an anodic electrolyte (14) with an anodic electroactive microorganisms,—a cathode chamber (21) with at least one biocathode (22), and a cathodic electrolyte (24) with a cathodic electroactive microorganisms. The anode chamber (11) is separated from the cathode chamber (21) by, running from the anode chamber to the cathode chamber, a cation exchange membrane (31) and an anion exchange membrane (32). The cation and anion exchange membranes are separated from each other by an inter-membrane chamber (30), and means for applying a potential difference between the interconnected bioanodes and the biocathode/biocathodes. The bioanodes and biocathode/biocathodes have active surfaces such that the total active surface of the biocathode/biocathodes (22) is greater than the total active surface of the two bioanodes (12, 13).
