The present invention discloses a new type of biofuel cell, based on the microbial regeneration of the oxidant, ferric ions. The bio-fuel cell is based on the cathodic reduction of ferric to ferrous ions, coupled with the microbial regeneration of ferric ions by the oxidation of ferrous ions, with fuel (such as hydrogen) oxidation on the anode. The microbial regeneration of ferric ions is achieved by chemolithotrophic microorganisms such as Acidithiobacillus ferroxidans. Electrical generation is coupled with the consumption of carbon dioxide from atmosphere and its transformation into microbial cells, which can be used as a single-cell protein.

L'invention concerne un nouveau type de pile à biocombustible fondé sur la régénération microbienne des ions ferriques oxydants. La pile à biocombustible est basée sur la réduction cathodique d'ions ferriques à des ions ferreux, associée à la régénération microbienne des ions ferriques par l'oxydation des ions ferreux, accompagnée de l'oxydation de combustible (par exemple, de l'hydrogène) sur l'anode. La régénération microbienne des ions ferriques est réalisées à l'aide de micro-organismes chimiolithotrophes, tels que Acidithiobacillus ferroxidans. La génération électrique est associée à la consommation de dioxyde de carbone atmosphérique et à sa transformation en cellules microbiennes, qui peuvent être utilisées comme une protéine d'organisme unicellulaire.
