Abstract

The organic-inorganic composite film was deposited on the 304 stainless steel as bipolar plate material for proton exchange membrane fuel cells by spin-coating method. As shown by XRD, N₂ adsorption-desorption and TEM, the composite films exhibit ordered mesoporous structures. The corrosion tests in 0.5M H₂SO₄ system displayed that, compared with 304SS, the composite films made corrosion potential shifted to positive direction by 250-1000mV (SCE) and corrosion current decreased by 1-3 orders of magnitude. Wherein, the C-50-60% composite film showed the optimal protective performance, its corresponding potentiostatic polarization process was extremely stable in the simulated fuel cells environment.
