Field Synergy Principle to Square and Trapezoid Types Fuel Cell Bipolar Plate of Mold Injection

It is a pretty new way to investigate different kinds of channel trough of fuel cell bipolar plates by filed synergy principle in mold injection, the simulation of filed synergy principle is similar to finite element method. However, to obtain better products, a number of questions, regarding to the material properties and process conditions, need to be fully understood. In this study, the complex flow behavior of melts under the assistance of mold flow analysis is conducted by examining the coupling effects of the process conditions and the material properties numerically. Therefore, the present study is to simulate these characteristics of filling, packing, cooling and warpage in mold injection with fiber orientation. In order to get better filling with fiber orientation of different troughs like square and trapezoid types of fuel cell bipolar plate in mold injection, channel shape of bipolar plate of fuel cell should be designed in mold. The result shows trapezoid channel of fuel cell bipolar plates with fiber orientation in injection molded fuel cell bipolar plates will get better quality and filling pattern. The effects of fiber orientation and welding line are also discussed in this paper.
