Bio-battery with enhanced yield

摘要

A novel cell including first and second chambers containing a solvent and separated by a wall permeable to the solvent and impermeable to hydronium and/or hydroxyl ions; a first electrode in the first chamber; a second electrode in the second chamber; a first redox couple in the first chamber comprising a first oxidizer and a first reducer taking part in first oxidation-reduction reactions resulting in an electron exchange with the first electrode; a second redox couple in the second chamber comprising a second oxidizer and a second reducer taking part in second oxidation-reduction reactions resulting in an electron exchange with the second electrode, the wall being impermeable to the first and second redox couples; and first enzymes or first microorganisms placed in the first or second chamber and promoting a third oxidation-reduction reaction resulting transforming a first substance to a second substance comprising acid or alkaline species.

主权项

1. A cell comprising:
first and second chambers containing a solvent and separated by a wall permeable to the solvent and impermeable to hydronium and/or hydroxyl ions; a first electrode at least partly arranged in the first chamber; a second electrode at least partly arranged in the second chamber; a first redox couple placed in the first chamber in contact with the solvent and comprising a first oxidizer and a first reducer taking part in first oxidation-reduction reactions resulting in an electron exchange with the first electrode; a second redox couple placed in the second chamber in contact with the solvent and comprising a second oxidizer and a second reducer taking part in second oxidation-reduction reactions resulting in an electron exchange with the second electrode, said wall being impermeable to the first and second redox couples; and first enzymes or first microorganisms placed in the first chamber or in the second chamber and promoting third oxidation-reduction reactions different from the first and second oxidation-reduction reactions resulting in the transformation of a first substance to provide a second substance comprising acid or alkaline species, which results in a pH variation and in a consecutive variation of the redox potential.
