Stainless steel bipolar plate coated with polyaniline/Zn-Porphyrin composites coatings for proton exchange membrane fuel cell.

Abstract:

: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 H2SO4 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.

  • Comparing supervised and unsupervised approaches to emotion categorization in the human brain, body, and subjective experience.

    abstract::Machine learning methods provide powerful tools to map physical measurements to scientific categories. But are such methods suitable for discovering the ground truth about psychological categories? We use the science of emotion as a test case to explore this question. In studies of emotion, researchers use supervised ...
