Title: Chantal Gondran: Innovator in Biofuel Cell Technology

Introduction

Chantal Gondran is a prominent inventor based in Grenoble, France. She has made significant contributions to the field of biofuel cell technology, holding 2 patents that showcase her innovative approach to energy solutions.

Latest Patents

One of her latest patents is the "Glucose Biofuel Cell." This invention is designed to be immersed in a liquid medium containing sugar and oxygen. The anode features an enzyme that catalyzes the oxidation of sugar, along with a redox mediator of low redox potential that facilitates electron exchange with the anode enzyme. The cathode is equipped with an enzyme that catalyzes the reduction of oxygen, paired with a redox mediator of high redox potential for electron exchange. Both the anode and cathode electrodes are constructed from a solid agglomerate of conductive material mixed with the appropriate enzyme and redox mediator, solidified with an electrode wire.

Another notable patent is the "Bio-battery with Enhanced Yield." This innovative cell consists of first and second chambers containing a solvent, separated by a wall that is permeable to the solvent but impermeable to hydronium and/or hydroxyl ions. It includes a first electrode in the first chamber and a second electrode in the second chamber. The first redox couple in the first chamber comprises a first oxidizer and a first reducer, facilitating oxidation-reduction reactions that result in electron exchange with the first electrode. The second redox couple in the second chamber comprises a second oxidizer and a second reducer, also enabling electron exchange with the second electrode. Enzymes or microorganisms are placed in either chamber to promote a third oxidation-reduction reaction, transforming a first substance into a second substance that includes acid or alkaline species.
