Due to their low cost, high strength, ease of machining and shaping into the sheets, as well as their corrosion resistance, stainless steels are considered to be good candidates for a bipolar plate material for the polymer electrolyte membrane fuel cells (PEMFCs). In this study, we have tested several stainless steels in simulated PEMFC environments for application as a bipolar plate material. Contact resistance and potentiondynamic polarization curves are measured. Additionally, we also measured their performance of single cell with stainless steel foam in the various flow-filed of the bipolar plate at 70℃, in comparison with graphite, such as polarization curves (I-V curves), EIS (Electrochemical Impedance Spectroscopy), CV (Cyclic Voltammetry), LSV (Linear Sweep Voltammetry) and lifetime curves. |
