Functionalized Modified Ti4O7 Polyaniline Coating for 316SS Bipolar Plate in Proton-Exchange Membrane Fuel Cells
In this paper, the PANI/PDA-Ti<sub>4</sub>O<sub>7</sub> composite coating was prepared on 316L by constant current deposition with a current density of 2.8 mA·cm<sup>-2</sup>, in which the Ti<sub>4</sub>O<sub>7</sub> powders were modified by PDA (polydopamine). The open-circuit potential of the obtained PANI/PDA-Ti<sub>4</sub>O<sub>7</sub> composite coating is about 365 mV<sub>Ag/AgCl</sub>, which is more positive than that of the bare 316L. During immersion in 1 M H<sub>2</sub>SO<sub>4</sub> + 2 ppm HF for 200 h, the high stable corrosion potential and the lower <i>R</i><sub>f</sub> indicate that the composite coating has long-term corrosion resistance.
