A stability study of platinized carbon black and carbon nanotubes nanocomposite as a fuel cell electrocatalyst

By cyclic voltammetry and rotating disk electrode investigated the stability of the composite catalyst Pt/C–CNT from electrochemical action through multiple changes of the electrode potential from –150 to 1000 mV vs. silver chloride reference electrode. Investigated: the dynamics of the electrochemically active surface area of platinum and electrode in whole, change of amount of quinone groups, change in density of the kinetic current reduction of air oxygen on the surface of the catalyst.

On the influence of the carbon material surface fraction determined by porosity on the linearity of the charge-discharge characteristics of DLSC

The electrical and chemical characteristics of nanocomposite materials based on carbon black for double-layer supercapacitors were investigated. It was shown that the highest values of the specific capacitive characteristics were obtained for carbon material SP4 which has the largest specific surface area (total capacity 228 F/g, reversible capacity 162 F/g).
