摘要

In this study, the formability of the metallic bipolar plates for PEMFCs were studied via DYNAFORM software and LS-DYNA and the performance and the electrochemical impedance the air-breathing PEMFC with the stamped metallic bipolar plates were tested analyzed. The simulation results show that the optimum stamping parameters for the SS316L are the flow channel depth of 0.8 mm, punch and die radius of 0.4 mm, stamping speed of 250 mm/s, blank thickness of 0.2 mm and the binder pressure of 200 kN. The maximum error between the real stamped flow channel depth and the target depth is 12.8%. With the stamped SS316L bipolar plate, which has an active area of 150×54 mm2, the air-breathing in this work has the maximum power density of 187.19 mW/cm2 at an operating temperature of 45°C, a torque of 30 kgf-cm, a hydrogen stoichiometric ratio of 1.5 and a relative humidity of 100%.
