Has been synthesized experimental samples electrocatalysts oxidation of hydrogen and oxygen electroreduction of high performance hybrid metal-based carbon nanostructures for catalytic membrane systems. It is shown that the composition of the liquid phase synthesis methods and affect the final characteristics obtained nanostructured Pt / XC72 electrocatalysts for hydrogen-oxygen PE. In different conditions of synthesis of nanoparticles of different size are formed, affecting the catalytic activity of electrocatalysts. Developed aerographic method of applying a catalytic ink proton-conducting membrane or the gas diffusion layer that promotes uniform formation of a catalytic layer and allows you to create OIE required power. Has been investigated Pt/C catalysts composed of active layers of hydrogen-air membrane-electrode unit. The optimum parameters for high OIE. Resource OIE test with cathodes based on synthesized catalysts was performed for 200 hours. With a constant load voltage of 0.6 V and a current density of at least 50 mA / cm2 OIE show stable performance at their maximum reduction of 10%.
