Project summary

Project provides the development and study of thin-film structures for principally-new type of the system for direct conversion of a chemical energy into an electric one of the basis of an electron catalytict cell (ECC).

Realizing Project, it is planned to perform a volume of studies, when the following designs will be developed:

– thin film structures, possessing of a catalytic external semiconducting layer activity in the hydrocarbon oxidation reactions and producing rectifying contacts with a single-sided electrical conduction between an external layer and a backing;


– gas-penetrable electrodes producing Ohmic contacts with a semiconducting layer surface;
– an experimental gas-sensitive pickup design and a stand for its testing.

The scientific Project realization results are expected to be:

– the studies of conditions for production of multilayer semiconducting catalytically - active rectifier valve structures by the techniques of vacuum and plasma sputtering, as well as by ion implantation;


– the studies of catalytical properties and electrophysical characteristics for the experimental samples of such structures;
– the precision of a theoretical ECC-model with due regard for the produced experimental characteristics.

Practical results of Project are expected to be:

– the production technology of thin-film catalytically-active rectifier valve structures by the methods of vacuum and plasma sputtering, as well as by ion implantation;


– an experimental gas-sensitive pickup sample of a new generation, much promising in the control over the content of fuel gases in the oxуgen-containing media, as well as the results of its tests at a special research stand.

Final results of Project are expected to be:

– the results of experimental and theoretical studies in thin-film catalytically-active rectifier valve structures for a principally-new type systems of direct chemical energy conversion into an electrical one on the ECC- basis;


– the design and technology of manufacturing an experimental ECC-model (as a gas -sensitive pickup) and the stand for its tests;
– the precision of the theoretical model which can be used in the ECC-calculations and designs for various purposes;
– the experimental gas-sensitive ECC-based pickup, the results of its tests and the test stand supplied with instrumentation.

The expected economical benefit from the usage of the Project results is related with an opportunity to produce the principally-new types of gas-sensitive pickups, sources of a current for stationary and transport facilities, combined sources of electricity/heat supply for industrial and domestic application and for other engineering devices and systems.

The proposed Project corresponds to the ISTC goals, since a given development is directly-related to conversion in the interests of commercial goods production in the branches dominantly-oriented to the development of arms, such as the atomic industry (radiation technologies, implementation of charged particle accelerators, radiolysis hydrogen control in nuclear reactors), space rocket technology (direct energy conversion systems), production and processing of chemical arms (means of chemical prospecting and protection). The scientists and specialists engaged in the studies at nuclear power facilities and in the direct energy conversion systems for military purposes are mainly involved in the Project activities. The Project realization will support specialists, taking part in it, providing them some prospects for professional occupation in the regions related with development of the new types of instrumentation, power production and other ECC-based systems.

The results produced in realization of given goals will be discussed with foreign collaborators, an exchange of scientific-engineering information will be performed. Participation of the leading

specialists of Project in International Conferences and Seminars on the problems of new energy source developments and applications will be provided.

The engineering approaches and the methodology in the Project realization will be based on the results previously-obtained by the Project participants in the development of direct energy conversion systems and on the results of long period studies in the ion implantation into various materials. The usage of a wide range of ion implantation technologies in Project can also be of a scientific and practical interest for developing solar batteries, using a short wavelength range of the spectrum and semiconducting wide zone materials for developing some electrically-controlled catalytic processes and other engineering systems.
