Field of studies:
The group (head: D.Sc. A. A. Nechitailov) specializes in the development of technologies for electrochemical power engineering, fuel cells (FCs), electrolyzers and supercapacitors. At the moment, the main work is carried out in the field of hydrogen energy including development of functional electrode materials for the proton-exchange membrane (PEM) FCs. The research is aimed at improving efficiency of energy conversion in electrodes. Special attention is paid to catalysts based on platinum as warranting the best efficiency, the Nafion polymer and various carbon materials such as carbon nanotubes, carbon black or graphenes.
Main achievements
Both fundamental and applied results were obtained of which the following are considered the most important:
- development of the materials exhibiting the advanced technical characteristics (power density 1 W/cm2, electrical efficiency about 50 %). The characteristics are obtained at the temperature of 80 °C, under pressure of 2 atm in an oxygen/hydrogen medium, loading condition for platinum on the cathode is about 0.1 g/kW;
- creation of the prototypes of power sources with rated power of 5 W and 50 W;
- development of the original technologies for electrode materials for low-temperature fuel cells whose characteristics are not inferior to the best world achievements. In these technologies, three fundamental principles are implemented: i) increase in the activity of platinum due to cocatalysis with functional groups on the carbon material, ii) formation of an island structure of a proton-conducting polymer (Nafion), and iii) creation of a highly porous electrode structure.
Cooperation:
A large fraction of works is being done in framework of partnership with the colleagues from the laboratory of Aleshin A.N. and the laboratory of Gurevich S.A. (Ioffe Institute). A part of the research is carried out jointly with specialists from Peter the Great St. Petersburg Polytechnic University, Southern Federal University and ParisTech. The group also cooperates with domestic producers of carbon materials and polymer materials: NanoTechCentre (Tambov) and Plasmas (SPb), Plastpolymer (SPb).
