| Sumario: | The proton exchange membrane fuel cells are the promising sustainable energy sources. The present study focuses on the enhancement the fuel cell performance and the protection of the stainless steel bipolar plate from the corrosion using polyaniline/Zn-Porphyrin composites coatings. The electrochemical properties (polarization and impedance) of the coated 303 stainless steel in 1.0 M H(2)SO(4) solution have been evaluated. The coated 303 stainless steel by new composites exhibits the excellent anti-corrosion activity towards corrosive fuel cell electrolyte. The polyaniline/Zn-Porphyrin composite gives an excellent performance by adding 1.0% of Zn-Porphyrin. This composite improves the output power of the fuel cell. |
