- W4300861305 abstract "A series of cathodic and anodic catalysts for alkaline H2-O2 fuel cells (FC) deposited on the surface of functionalized and nitrogen-doped carbon nanotubes (CNT) was synthesized and studied by various structural and electrochemical methods. It was established that, due to the minor defect structure, CNTNaOH (functionalized in alkali) exhibit high corrosion stability. A further increase in the activity in the oxygen reduction reaction (ORR) and the stability of CNTs is observed following their doping with nitrogen. The high activity of CNTNaOH+N is attributed to pyridine groups and the increased electrical conductivity of this catalyst. It was shown that CNTNaOH comprise effective substrates for hydrogen oxidation reaction catalysts. The PtMo/CNTNaOH system containing 12 wt% Pt at a molar ratio of PtMo= 1:1 is characterized by the highest catalytic activity among investigated anode platinum and non-platinum catalysts. The use of this catalyst made it possible to reduce the content of platinum to 0.1–0.2 mg/cm2, while preserving the characteristics that significantly exceed those of the active layer containing 60Pt/C (HiSPEC 9100) catalyst (0.6 mgPt/cm2)." @default.
