    Corrosion behavior of carbon composite bipolar plate for alkaline fuel cell
    (2011) Avtaç A.; Sanli A.E.; Ay F.
    Composite bipolar plates for direct peroxide/peroxide fuel cell (DPPFC) were prepared using natural graphite and phenol formaldehyde resin. The corrosion behavior of composites in DPPFC environments was studied using polarization resistance and electrochemical impedance spectroscopy (EIS) methods. The plates were characterized for electrical conductivity, mechanical strength and corrosion resistance. The corrosion current density at the optimum composition was found to be 16.82 mA cm- 2 for alkaline fuel cell environments.

    Investigation of the electro-oxidation of artificial Black Sea water by cyclic voltammetry on molybdenum (II)
    (Elsevier Ltd, 2014) Sanli A.E.; Aytaç A.; Mat M.
    The electro-oxidation of H2S in Black Sea water to generate electricity was investigated. MoS2 exhibited catalytic activity toward the oxidation of H2S in artificial sea water. The catalytic activity of molybdenum sulfide was found to depend on the electrolyte pH and on the temperature. Cyclic voltammograms taken in the artificial sea water containing hydrogen sulfide at pH = 14 exhibited a peak at 500 mV related to the oxidation of HS-. Furthermore, the peak current of the MoS 2 electrode increased to 400 mA g-1 from 250 mA g -1 (approximately 1.6-fold) when the temperature was increased from 353 K to 363 K. © 2014, Hydrogen Energy Publications, LLC.
