本研究在探討一種新式有效的方法來研究不同不銹鋼S316L玻纖與冷卻管數目的燃料電池雙極板不同溝槽的射出分析。本文利用Moldex 3D軟體模擬質子交換膜雙極板燃料電池複合雙極板模流，其射出的流動行為先利用有限元素法切割網格並設定材料與設出參數來分析流動波前的情況是否均勻。分析包括充填保壓冷確翹曲與玻纖配向。為了在雙極板溝槽在U型與V型下可以得到較佳的充填,充填的方式與流道需要最好的設計與佈置。結果顯試示高含量玻纖的燃料電池雙極板在充填上可獲得較佳的充填模式與高品質。

It is an effective new way to investigate different amounts of S316L fiber orientation and cooling tubes of the proton exchange membrane fuel cell (PEMFC) bipolar plates mold injection simulation by Moldex 3D. The mold flow simulation is investigated by finite element method.In this study, the complex flow melting behaviour 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 aims to simulate these characteristics of filling, packing, cooling and warpage distributions for mold injection with fiber orientation. In order to get better filling with fiber orientation of different trenches, like U and V types of fuel cell bipolar plates in mold injection, the channel shape of the fuel cell bipolar plate mold should be designed. The simulation result shows that higher amount of fiber orientation inside the channel of fuel cell bipolar plates will get better quality and filling pattern.
