Description

<jats:title>Abstract</jats:title> <jats:p>Output characteristics of sugars/KOH fuel cells using PEDOT*PSS, CNT, and PtRu composite (anode)/cellophane/Pt (cathode)/air have been studied. The maximum power density of glucose demonstrated 60 mWcm−2, being the best in the world. The relative outputs were 1, 0.37, 0.51, 0.42, and 0.006 for glucose, fructose, lactose, maltose, and sucrose, respectively, depending on the reducibility of sugars. The hydrolysis of sucrose with acids resulted in the enhancement of output. The coulombic and energetic conversion efficiencies are discussed comparing experimental and theoretical estimations.</jats:p>
