Regeneration of a bio-electrode of a bio-electrochemical device - device and associated method

Regeneration of a bio-electrode of a bio-electrochemical device - device and associated method - EP-3850126-A1 (2021)

A bio-electrochemical device comprising at least one bio-anode immersed in an electrolyte containing anodic electroactive microorganisms characterised in that it comprises a diffuser, connected to a gas source, and arranged in a zone situated below or in the lower part of the bio-anode, the diffuser having outlet openings for the gas capable of generating gas bubbles sweeping the surface of this bio-anode and/or causing turbulences around it, the bubbles being used to regenerate this bio-anode, during the functioning of the electrochemical device. A method for regenerating a bio-anode by means of the above device, that can be combined with a reduction in the difference in potential between the bio-anode and the cathode.
