This study is to investigate integrated assessment on the flow channel and glove in channel of bipolar plate for PEMFC. We used two software Multiphysics and Moldex3d 9.1 to simulate these characteristics of gas flow pattern, filling, packing, cooling and warpage. In order to get better performance on bipolar plate with fiber orientation for different types like square and trapezoid fuel cell bipolar plate, the field synergy principle is used to determine the better type of channel shape of bipolar plate of fuel cell The result shows trapezoid channel of fuel cell bipolar plates with fiber orientation in injection molded fuel cell bipolar plates will get better quality for both simulations. The effects of fiber orientation is also discussed in this paper.
