Abstract
Disclosed is a micro power cell capable of being applied as an energy source and utilizing a streaming potential phenomenon occurring in accordance with an electrokinetic principle when an electrolyte aqueous solution flows in the microchannels piled up in several layers. The streaming potential cell consists of a PDMS microfluidic-chip fabricated by MEMS process as well as micromachining technology. The microfluidic-chip is formed with multi microchannels radially arranged in parallel with each other around a center of a disk at a regular interval. The disk type multi microchannel can achieve uniform inflow and outflow effects. According to the invention, there is provided a cell device comprising a pile-up chip having a number of disk type microfluidic-chips with the optimal structure of flow-in and flow-out of a fluid, a distributor, a collector, an electrode insertion part, etc.
