近年來在燃料電池中，雙極板決定了大部分的體積和重量，由於傳統石墨雙極板的加工費用相對較高，也大大增加了整個燃料電池組的成本。故解決電池成本和重量有重要意義。本研究旨在針對雙極板的沖壓成型參數進行成型性的有限元素摸擬分析並探討。模擬中分別改變不同的流道型式及沖壓參數，經由有限元素軟體LS-DYNA求解分析，在變薄率與回彈量間取得一個最佳值，並觀察這些參數對兩者的影響程度。接著量測沖壓後鈑件流道成型深度與預設值做誤差比較，並組裝成單電池測試性能的變化。
模擬中將改變不同的流道參數包括：流道數目、流道深度、模具倒圓角、鈑件厚度，鈑件厚度的改變對變薄率與回彈量的影響會形成相反的趨勢。由模結果可得知流道成型性主要會因流道與肋條的寬度以及流道長度有關，在9-Channel流道形式下會有最好的成形成型性與最小的回彈產生。
實驗中所量測得板件流道深度較均勻，但成型率有比較低的情形，故可改變加工製造方式來改善此現象。墊片溝槽量測中，分別用兩種量測方式下得到的結果，在Sample1下誤差最大為18.3%，實際鈑件深度差為0.109mm；Sample2下誤差最大為25%，實際鈑件深度差為0.110mm，從以上結果可知溝槽深度有不均勻的現象。

Recently, metallic bipolar plates (MBP) determines most of the volume and weight, since the conventional graphite bipolar plates are relatively high processing costs, but also greatly increase the cost of whole fuel cell stack. Therefore, to solve the cost and weight problem of fuel cell are very important. The goal of this study is to simulate the stamping process of MBP. To find out how the flow-field pattern of the flow channel and the conditions of stamping process changing affects thinning rate and springback by using finite element analysis of LS-DYNA and to get the best experiment’s parameters. In the simulation, the parameters, such as metal’s thickness, channel depth, and springback rate were changed. The best flow-field pattern of 9-Channel was found from the results. In the experimental work, two methods were used to measure channel depth after stamping processing. In sample 1, the biggest deviation is 18.3%, and the actual depth of sheet is 0.109mm. In sample 2, the biggest deviation is 25%, and the actual depth is 0.110mm.These results showed that the phenomenon of uneven depth of the channels. It also showed that changing thickness is inversely proportional to thinning rate and spring back rate, and there are better dimension of channel depth. It can be improved by changing manufacturing method.
