Abstract
Abstract Stainless steels, as low cost materials, are attractive for proton exchange membrane fuel cells (PEMFC) bipolar plates. However, these metallic alloys require surface coatings or treatments to enhance its corrosion resistance and surface conductivity in {PEMFC} environments. In this study, response surface methodology based on Box-Behnken design was employed to investigate the influence of time, activator content and temperature on corrosion current density of pack chromised 304 stainless steel in simulated {PEMFC} environment of aerated 0.5 M {H2SO4} + 2 ppm {HF} at 70
