DEVICE FOR CONVERTING BIOMASS TO A REDUCED MEDIATOR, SYSTEM FOR CONVERTING BIOMASS INTO DIHYDROGEN COMPRISING SAME, AND ASSOCIATED PROCESS

摘要

The invention relates to a device (1) for converting biomass (10) into a redox mediator (11) in reduced form (110), comprising an assembly (12) of microbial fuel cells (120) comprising: a first compartment (1200) comprising an anode (1200a) and fermentative microorganisms (1200b) and electroactive microorganisms (1200b), and a second compartment (1201) comprising a cathode (1201a) and a solution (1201b) comprising the mediator (11), and an external resistor (1203) connecting the cathode (1201a) and the anode (1200a). The value of the external resistor (1203) of at least one microbial fuel cell (120) is distinct from that of at least one other microbial fuel cell (120). The device thus makes it possible to induce segregation of the fermentative microorganisms and of the electroactive microorganisms along the assembly (12).
