雙極板的設計決定了燃料電池大部分的成本，也是影響電池性能的主件之一。在雙極板的材料上，我們選擇用碳纖維作為雙極板的電流收集器，這不僅降低了燃料電池的重量，也因為碳纖維的低成本，使之商業化潛力無窮。而碳纖維以外雙極板的組件製作上，則採用3D Printer技術製作，因為其在研發上的的便利性。
3D Printer製作之組件與碳纖維束的組裝黏合，製成雙極板，再據以組裝成兩個Cell的燃料電池堆，並探討非均質碳纖維雙極板的燃料電池堆的性能表現，與射出成形製作上之差異。

The design of the bipolar plates decides most of the cost of Fuel Cell.Bipolar plate has a great influence in Fuel Cell performance.We choose carbon fiber as the current collector of bipolar plates.It reduce weight and has great potential in business because it’s low cost.The other parts of bipolar plate makes by 3D Printer except carbon fiber.We choose 3D Printer to make bipolar plates because it’s convenient in research and design.
The combination of carbon fiber and the other parts made by 3D Printer. Assemble it into bipolar plate and assemble bipolar plate into a 2 cell Fuel Cell. Investigate the performance of heterogeneous composite bipolar plate Fuel Cell and different of injection molding production.
