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

哥伦比亚大学的Scott A.Calabrese Barton被支持在植物中使用环境有机燃料为生物燃料电池制造高倍率生物催化电极。这项工作借鉴了目前正在进行的生物催化电极研究的成果，将重点放在(1)燃料组成和葡萄糖-果糖-蔗糖的比例；(2)葡萄糖氧化酶、寡糖脱氢酶和转移酶-变位酶-葡萄糖氧化酶等酶系统；(3)通过氧化还原聚合物进行电子中介，以促进低电极电位下的高速电子转移；(4)作为优化的阳极支撑结构的高孔碳纤维；以及(5)对流效应及其如何影响电极孔隙度和整体电池几何形状。数学模型将被用来指导在阳极系统和整个生物燃料电池中的实施。这项工作将有助于加深对植物来源的生物催化能源产生的理解。除技术影响外，该项目还包括与公立学校系统的联系以及研究与教育的结合。该奖项由美国国家科学基金会数学和物理科学局和情报界共同支持。反恐方法方案支持基础研究和劳动力发展方面的新概念，有可能为国家安全作出贡献。

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.
