Serpentine Flow Channel

Simulations results are presented in this paper, which were obtained on investigating the effects of flow patterns on the hydrogen consumption in a proton exchange membrane fuel cell (PEMFC). In this study, a 3-D computational model was developed to investigate the influence of the flow and depth of the channels on hydrogen consumption. Simulation results showed the influence of depth in the distribution of hydrogen concentration. The flow channel pattern adopted in this study is the serpentine flow channel.

Geometrical Features

Due to lack of desirable mechanical properties of silicon substrate; the current trend of micro-fabrication technology is towards metallic materials. In this study, the electrochemical micromachining (EMM) technology is developed to fabricate micro-scale flow channels on thin metallic 316L stainless steel plate. The cathode electrode, the tool, is the mirror image of flow channels. It was produced by the MEMS and UV-LIGA technology and the size is 200μm in width and 500μm in height for the intension to fabricate a serpentine flow channel of 200μm in both depth and width. Because of the electrode size, the process control parameters and geometrical features surpassed conventional and CMOS methods. The flow channels on 0.6mm thick SS 316L plates were fabricated by EMM process within 30 seconds with effective area of 625mm2. The dimensions of flow channel were varying from 1504m to 5004m in width and about 2004m in depth. The results demonstrate the EMM technology produces good quality metallic flow channels efficiently.
