| In this research, rubber pad forming process of metallic bipolar plates made of stainless steel 316L with a thickness of 0.1 mm has been studied. In addition, a rubber pad made of polyurethane with the hardness number of shore A 85 and a thickness of 25mm is used in order to apply pressure to the plate to form the sheets. In order to study the effect of die clearance on depth filling, two die sets with different clearances were made. The results showed that when clearance is applied between punch die and matrix, the amount of uniformity becomes more in the depth of stuffed channel. But, the rubber pad is destroyed after some forming operation and plastic deformation occurs in it. Also, in the die set with the lower clearance, the amount of rubber pad life has been increased and the amount of flow channel depth gets greater. In the research results, it was determined that when the channel depth is small and a rubber pad is used with a higher hardness, the die set with a clearance has more favorable results due to uniformity in the flow channels’ depth. However, by increasing the depth of bipolar plate channels, using die sets with lower clearance are better due to the increasing the rubber pad life. | ||
