为了更好地利用金属双极板来生产金属燃料电池并使其成为可行的技术，我们必须具有用于产生微尺度流动通道的高效且成本有效的制造工艺。在这项研究中，电化学微加工（EMM）过程中开发。为了更好地进行工艺控制，采用有限元分析确保机床平台的刚度;采用电场分析进行电极设计;采用电解液流分析进行夹具设计和操作参数的选择。最后，在厚度为50 mm × 0.6 mm的SS 316不锈钢板上制造深200 μ m、宽500 μ m的流道。(C)2008 Elsevier B. V.保留所有权利。
In order to take better advantage of metallic bipolar plates for producing metallic fuel cells and make it a feasible technology, it is essential that we have an efficient and cost effective fabrication process for creating micro-scaled flow channels. In this study, an electrochemical micro-machining(EMM) process is developed. In order to have better process control a finite element analysis is employed to ensure machine tool platform rigidity; an electric field analysis is applied for the electrode design; and an electrolytic flow analysis is carried out for the fixture design and the selection of the operational parameter. Finally, flow channels measuring 200 mu m in depth and 500 mu m in width are fabricated on SS316 stainless steel sheets measuring 50 mm x 0.6 mm thick. (C) 2008 Elsevier B.V. All rights reserved.
