The purpose of the work is to synthesize and investigate laws of electrochemical behavior nanosized active substances for chemical power sources. Methods of researches are the studying of conductivity and electrochemical characteristics, electron microscopy and mathematical modeling. The solution structure Influence on conductivity "air-electrolyte" phase interface is investigated. The technique of nanocatalysts for fuel cell synthesis is developed. It is shown that activation of the graphite carrier by platinum with tetraethoxysilane sol allows to reduce quantity of platinum. The technique and formation process nanosized crystals NіOOH from nickel hydroxide is proposed. The thin nickel films on a surface of Nі(OH)2 grains have been synthesized. The structure, conductivity and electrochemical characteristics of "encapsulated" nickel hydroxide have been investigated. The mathematical model of electrochemical transformations in crystals Nі (OH)2 and model of nanodispersed substances recrystallization have been developed. It is possible to developed object of research for optimisation of electrochemical processes and optimization of power source electrodes. Scopes of usage are higher education (M 80.30.0) and manufacture of galvanic cells (electric accumulators and primary elements) (DL 31.40.0).
