摘要：
A planar microfluidic membraneless flow cell. The design eliminates the need for a mechanical membrane, such as a polyelectrolyte membrane (PEM) in a fuel cell, by providing a flow channel in which laminar flow regimes exist in two fluids flowing in mutual contact to form a "virtual interface" in the flow channel. In the flow cell, diffusion at the interface is the only mode of mass transport between the two fluids. In a fuel cell embodiment, a planar design provides to large contact areas between the two streams, which are fuel and oxidant streams, and between each stream and a respective electrode. In some embodiments, silicon microchannels, of fixed length and variable width and height, have been used to generate power using formic acid as fuel and oxygen as oxidant. Power densities on the order of 180 µW/cm 2 have been obtained using this planar design.
摘要（中）：
平面微流体无膜流动池。 该设计通过提供流动通道来消除对燃料电池中的诸如聚电解质膜（PEM）的机械膜的需要，其中流动通道中两种流体中存在层流状态以相互接触流动以形成“虚拟界面” 流通道。 在流动池中，界面处的扩散是两种流体之间唯一的质量传输模式。 在燃料电池实施例中，平面设计提供两个流（其为燃料流和氧化剂流）之间以及每个流与各个电极之间的大接触区域。 在一些实施例中，具有固定长度和可变宽度和高度的硅微通道已被用于使用甲酸作为燃料和氧气作为氧化剂来发电。 使用这种平面设计已经获得大约180μW/ cm 2 SUP的功率密度。
