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 la cathode qui n'était pas en contact avec le gel était exposée à l'air. De plus, la surface de l'anode qui n'était pas en contact avec le gel était en contact avec le liquide combustible pour empêcher le gel de sécher. La densité de puissance de la pile à combustible a été améliorée en augmentant l'apport d'oxygène provenant de l'air et la durée de vie a été améliorée en maintenant le gel humide, c'est-à-dire que la structure proposée était un type hybride présentant les avantages à la fois du gel combustible et du liquide combustible. Le rendement a augmenté presque jusqu'à celui de la simple utilisation de gel combustible et n'a pas diminué de manière significative au fil du temps. La densité de puissance maximale dans le système proposé était d'environ 74.0 µW/cm2, soit une amélioration d'environ 1.5 fois celle dans le cas de l'utilisation de combustible liquide. La densité de puissance après 24 h était d'environ 46.1 µW/cm2, soit 62 % de la valeur initiale.

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 cathode surface not contacting the gel was exposed to air. In addition, the anode surface not contacting the gel was in contact with fuel liquid to prevent the gel from being dry. The power density of the fuel cell was improved by increasing oxygen supply from air and the lifetime was improved by maintaining wet gel, that is, the proposed structure was a hybrid type having advantages of both fuel gel and fuel liquid. The output increased almost up to that of just using fuel gel and did not decrease significantly over time. The maximum power density in the proposed system was approximately 74.0 µW/cm2, an enhancement of approximately 1.5 times that in the case of using liquid fuel. The power density after 24 h was approximately 46.1 µW/cm2, which was 62% of the initial value.
