L’amélioration du rendement et de la durée de vie est un problème pour les biopiles. Une structure a été adoptée dans laquelle la gélification mélangée à de l'agarose et du carburant (fructose) était prise en sandwich par des électrodes en fibre de carbone recouverte de graphène. La surface de l'électrode qui n'était pas en contact avec le gel était exposée à l'air. De plus, des rainures ont été ajoutées à la surface du gel pour augmenter encore l’apport d’oxygène. La densité de puissance de la pile à combustible a été examinée en termes de surface d'électrode exposée à l'air. Le rendement augmente presque proportionnellement à la surface de l'électrode exposée à l'air. L'optimisation de la concentration du carburant, du gel et de la quantité d'enzyme à la cathode a également été examinée. La densité de puissance maximale dans le système proposé était d'environ 121 μW/cm2, soit une amélioration d'environ 2.5 fois celle dans le cas de l'utilisation de combustible liquide. Pour la densité de puissance après 24h, le gel combustible était supérieur au liquide combustible.

Abstract: Improvement of output and lifetime is a problem for biofuel cells. A structure was adopted in which gelation mixed with agarose and fuel (fructose) was sandwiched by electrodes made of graphene-coated carbon fiber. The electrode surface not contacting the gel was exposed to air. In addition, grooves were added to the gel surface to further increase the oxygen supply. The power density of the fuel cell was examined in terms of the electrode area exposed to air. The output increased almost in proportion to the area of the electrode exposed to air. Optimization of the concentration of fuel, gel, and the amount of enzyme at the cathode were also examined. The maximum power density in the proposed system was approximately 121μW/cm2, an enhancement of approximately 2.5 times that in the case of using liquid fuel. For the power density after 24h, the fuel gel was superior to the fuel liquid.
