Development of electrochemical devices based on nanocomposite materials

Abstract

The problems of development portable low-temperature hydrogen-air solid polymer electrolyte fuel cells (SPEFC), medium-temperature methane-air fuel cells (SOFC) and supercapacitors (SC) with pseudocapacity effect are described in the article. These devices are promising to use in a variety of vehicles, including the sector of the magnetic levitation transport, as an alternative to low-speed movement. The current trends in the development of nanocomposite electrode materials, electrolytes SPEFC, SOFC and the SC are analyzed briefly. Examples of the use of materials synthesized by various methods, including the sol-gel technology are, presented in the article
