Abstract: front page image
(EN)The present invention discloses a new type of bio-fuel 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, at a pH less than about 1.2, with fuel (such as hydrogen) oxidation on the anode electrode. The microbial regeneration of ferric ions is achieved by microorganisms such as Leptospirillurn ferriphilum. 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.
(FR)La présente invention concerne un nouveau type de pile à biocombustible, basé sur la régénération microbienne de l'oxydant, les ions ferriques. La pile à biocombustible est basée sur la réduction cathodique d'ions ferriques en ions ferreux, couplée à la régénération microbienne des ions ferriques par l'oxydation d'ions ferreux, à un pH inférieur à environ 1,2, avec une oxydation de combustible (tel que l'hydrogène) sur l'électrode anodique. La régénération microbienne des ions ferriques est effectuée par des micro-organismes tels que Leptospirillum ferriphilum. La génération électrique est couplée avec la consommation de dioxyde de carbone provenant de l'atmosphère et sa transformation dans les cellules microbiennes, qui peut être utilisé en tant que protéine monocellulaire.
