本文讨论了一种新颖的微流体燃料电池概念，该概念利用微尺度上多流层流的发生来保持燃料和氧化剂流分离但处于扩散接触。该系统由一个 Y 形微流体通道组成，其中含有燃料和氧化剂的两股液体流合并，并继续在相对壁上的两个覆盖催化剂的电极之间平行层流流动，而不会发生湍流混合。初步结果表明，这种新颖的燃料电池概念可能会导致微观尺寸的高效室温电源的开发，其性能与通常在 60 至 80 摄氏度之间运行的基于传统聚合物电解质膜的微型燃料电池相当或更好。 (C) 2004 Elsevier B.V. 保留所有权利。
This paper discusses a novel microfluidic fuel cell concept that utilizes the occurrence of multi-stream laminar flow at the microscale to keep the fuel and oxidant streams separated yet in diffusional contact. The system consists of a Y-shaped microfluidic channel in which two liquid streams containing fuel and oxidant merge and continue to flow laminarly in parallel between two catalyst-covered electrodes on opposing walls without turbulent mixing. Preliminary results indicate that this novel fuel cell concept may lead to the development of efficient room temperature power sources of microscopic dimensions that are comparable or better in performance than conventional polymer-electrolyte-membrane based microfuel cells that typically operate between 60 and 80degreesC.
