ACT/SGER: Biofuel Cells Operating on Ambient Organic Fuels for Distributed Sensor Networks

哥伦比亚大学的斯科特·a·卡拉布雷斯·巴顿（Scott A. Calabrese Barton）利用植物中的环境有机燃料为生物燃料电池创造高速率的生物催化电极。这项工作借鉴了正在进行的生物催化电极研究的结果，并将重点关注(1)燃料组成和葡萄糖-果糖-蔗糖的比例；(2)酶系统，如葡萄糖氧化酶、低聚糖脱氢酶和逆酶-诱变酶-葡萄糖氧化酶；(3)通过氧化还原聚合物进行电子中介，促进低电极电位下的高速率电子转移；(4)采用高多孔碳纤维作为优化的阳极支撑结构；(5)对流效应及其对电极孔隙率和整体电池几何形状的影响。数学模型将用于指导阳极系统和整个生物燃料电池的实施。这项工作将有助于加强对植物源生物催化能源产生的理解。除了技术影响外，该项目还包括与公立学校系统的联系以及研究和教育的整合。该奖项由美国国家科学基金会数学与物理科学理事会和情报界联合支持。反恐方法项目支持基础研究和劳动力发展方面的新概念，这些新概念有可能为国家安全做出贡献。

Scott A. Calabrese Barton, Columbia University, is supported to create high-rate biocatalytic electrodes for biofuel cells using ambient organic fuels in plants. The work draws on results from ongoing studies in biocatalytic electrodes and will focus on (1) fuel composition and glucose-fructose-sucrose proportions; (2) enzyme systems such as glucose oxidase, oligosaccharide dehydrogenase and invertase-mutarotase-glucose oxidase; (3) electron mediation through redox polymers to facilitate high-rate electron transfer at low electrode potential; (4) highly porous carbon fibers as optimized anode support structures; and (5) convection effects and how they will impact electrode porosity and overall cell geometry. Mathematical models will be used to direct implementation in the anode system and in the complete biofuel cell. This work will lead to enhanced understanding of biocatalytic energy generation from plant sources. In addition to the technological impact, this project also includes outreach to the public school systems and the integration of research and education.
