Реферат: A sharp increase in the cathode potential (up to 1.4 V. vs. RHE) due to the simultaneous presence of oxygen (air) and hydrogen in the anode side is the main degradation cause of Pt/C catalysts for polymer electrolyte fuel cells (PEMFC) using as a power source for cars. This potential is much higher than the carbon oxidation potential, so the corrosion resistance of a carbon support is an important parameters of the PEMFC effective operation. In this paper, the stability of carbon support was improved by modifying the surface under different conditions. Modification of commercial carbon black KetjenBlack DJ-600 by pyrocarbon and nitrogen was carried out in order to investigate the influence of these additives on the support corrosion resistance. It was shown that the modification of the carbon blacks with both nitrogen and pyrocarbon improves the corrosion stability of the composite materials.
