Abstract

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 80 °C.

基于层流的微流体燃料电池
本文讨论了一种新型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流和氧化剂流的分离但又保持扩散接触。该系统由一个y形的微流控通道组成,在该微流控通道中,含有燃料和氧化剂的两股液体流合并并继续在相对壁上两个覆盖着催化剂的电极之间层流平行流动,没有湍流混合。初步结果表明,这种新型燃料电池概念可能会导致微观尺寸的高效室温电源的发展,其性能与传统的聚合物电解质膜微燃料电池相当或更好,通常在60至80°C之间工作。
