Summary

The work aim consists in creation of new nanocomposites on the basis of complex nickel-, manganese-, cobalt-containing oxides for electrode materials to fuel cells, oxygen membranes and chemical reactions accelerants for disposal of harmful chemical gases - production wastes. The topicality of the work is determined by global development trends in the sphere of energetics and ecological safety, according to which more attention is paid to the direct conversion of chemical energy to electrical energy using fuel cells; the environmental standards to production are becoming stricter.

Description

The authors offer original methods of obtaining nanocomposite ceramics which consists of particles with various chemical compositions. The method comprises several stages: obtaining of conventional material with subsequent reintegration and oxidation at low temperatures, in order to obtain gasproof materials the compaction method under high pressure at moderate temperatures is used.
