This paper reports the analytical detection and energetic properties of a glucose-fed Direct Catalytic Fuel Cell (DCFC) operated in association with yeast cells (Saccharomyces Cerevisiae). The cell was tested in a potentiostatic mode, and the operating conditions were optimized to maximize the current produced by a given concentration of glucose. Results indicate that the DCFC is characterized by a glucose detection limit of the order to 21 mmol L. The cell was used to estimate the "pool" of carbohydrate content in commercial soft drinks. Furthermore, the use of different carbohydrates, such as fructose and sucrose, has been shown to result in a good current yield.
本文报道了与酵母细胞（酿酒酵母）联合运行的葡萄糖-fed 直接催化燃料电池（DCFC）的分析检测和能量特性。该电池在恒电位模式下进行测试，并优化了操作条件，以最大限度地提高给定浓度葡萄糖产生的电流。结果表明，DCFC 的葡萄糖检测限为 21mmol L 左右。该电池用于估计商业软饮料中碳水化合物含量的“池”。此外，使用不同的碳水化合物，如果糖和蔗糖，已被证明可以产生良好的电流产量。
