Abstract：

The roll shape for the metal pole plate flow channel of hydrogen fuel cell which was prepared by the rolling process was designed, and the rolling process of 316 L stainless steel pole plate flow channel was numerically simulated. Then, taking the maximum thinning ratio, the maximum depth deviation ratio as evaluation indexes, the influences of roll shape parameters, such as punch height, width, draft angle and fillet radius on the depth and thickness for the forming of pole plate flow channel were studied. The results show that when the punch height increases from 0.30 mm to 0.40 mm, the maximum equivalent stress and the maximum thinning rate of metal pole plate flow channel increases, and its maximum depth deviation rate decreases. When the punch width increases from 1.6 mm to 1.8 mm, the maximum equivalent stress and the maximum thinning rate of metal pole plate flow channel decreases, and its maximum depth deviation rate increases. When the fillet radius of punch increases from 0.15 mm to 0.25 mm and the draft angle of punch increases from 15° to 25°, all evaluation indexes of metal pole plate flow channel decrease. In addition, using the range analysis method, it is found that the fillet radius is the main factor affecting the rolling of pole plate flow channel, and the experiment verification for the flow channels with different fillet radiuses of punch is carried out.
