출력과 수명의 향상은 바이오연료전지의 과제이다. 아가로스와 연료(과당)을 혼합한 겔화를 그래핀 코팅 탄소섬유로 만든 전극에 끼운 구조를 채택했다. 겔과 접촉하지 않는 전극 표면은 공기에 노출되었습니다. 또한, 산소 공급을 더욱 증가시키기 위해 겔 표면에 홈을 추가했습니다. 연료전지의 전력밀도는 공기에 노출되는 전극 면적으로 조사하였다. 출력은 공기에 노출된 전극의 면적에 거의 비례하여 증가했습니다. 연료, 겔 농도, 음극에서의 효소량 최적화도 검토했다. 제안된 시스템의 최대 전력밀도는 약 121μW/cm이다.2, 액체 연료를 사용하는 경우에 비해 약 2.5배 향상됩니다. 24시간 후 출력밀도에서는 연료겔이 연료액체보다 우수하였다.

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.
