本研究以質子交換膜燃料電池 ( Proton Exchange Membrane Fuel Cell, PEMFC ) 之雙極板為例，使用Moldex3D模流分析軟體作含纖維材料流動分析，應用射出成型製程製作雙極板，並以掃描式電子顯微鏡( Scanning Electron Microscopy, SEM )觀察纖維排向。
研究中以複合材料 PA6( Polyamide, Nylon6 )+ 40%CF和30%CF碳纖維( Carbon Fiber )，纖維(長度200μm/直徑10μm)，運用田口方法分析實驗，流道採用圓角設計，成品尺寸為100mmX100mmX3.6mm，流道寬度及深度均為1.2mm，並以直交表不同射出製程條件：流道配置方向(分別垂直與平行充填方向)、材料溫度、模具溫度、射出壓力、保壓壓力、背壓、充填速度、螺桿轉速，實驗因子並加以量測所成型的試片。
研究結果顯示製程參數，當流道垂直於充填方向時，會使纖維產生翻滾而糾結在一起，而降低電阻值；流道平行於充填方向時，具有提升電阻均勻性。

This research took bipolar plate of Proton Exchange Membrane Fuel Cell (or PEMFC) as the study case, and used Moldex3D mold flow analysis software to analyze the flow of fiber material. The bipolar plate was fabricated through injection molding process, and observed the fiber orientation with Scanning Electron Microscopy (or SEM).
This research used PA6 (Polyamide, Nylon6) and +40% or 30% carbon fiber. Fiber (Length 200μm / Diameter 10μm). Taguchi methods was utilized to analyze the experiment. It adopted fillet (round corner) design on the channel, and the finished product had a size of 100mmX100mmX3.6mm, and the channel was 1.2mm in its width and depth. Different injection process conditions were used: channel configuration direction (parallel and vertical to filling direction respectively), melt temperature, mold temperature, injection pressure, hold pressure, back pressure, injection rate and screw speed. Experimental factors were applied to mold test pieces and measured.
The results of this research showed that the fiber would turn around and entangle together, and thus decreased the electrical resistance when the channel was vertical to the filling direction. The uniformity of resistance would be increased when the channel was parallel to the filling direction.
