Project summaryThe objective of the project is the development of techniques for functional materials as thin-film formation for high-temperature solid oxide fuel cells (SOFC) and investigation into their properties.
At present the pressing and subsequent high-temperature sintering methods, widely applied in practice, are used more often in operating samples of electrochemical generators (EG) for manufacturing of SOFC. Despite of their relative simplicity and low cost, they have limited application in developments, which are directed on increase of SOFC specific characteristics due to minimization of thickness for functional layers of SOFC components - electrolyte, cathode, anode and current collectors. In this connection attention of SOFC materials developers is more and more attracted to film technologies for materials formation and among them - vacuum - plasma and plasmachemical technologies.
Within the frameworks of this project it is supposed, basing on significant experience of Russian and Ukrainian scientists in the field of condensation with ionic bombardment (CIB), atom -ionic spraying, plasma and vacuum - plasma spray deposition methods, to study possibility to make SOFC film materials by these methods. The characteristics of the produced film SOFC materials will be investigated (structure, morphology, phase composition etc.), experimental samples of thin-film cells will be made and their functional properties will be investigated.
Project performance will be carried out as cooperation of high-skilled weapon scientists and experts of Russian Federal Nuclear Center- All-Russia Research Institute of Technical Physics (RFNC-VNIITF), Snezhinsk, in the frameworks of ISTC and the scientists and technical experts of Ukraine: Institute of Applied Physics (Sumy city), "STIN" Ltd., (Kharkov), Institute of Magnetics Studies, (Kiev), at financial support of STCU (project # 1054/S of February 26, 1997).
Project performance will allow to advance in the field of new methods development to produce thin films from SOFC materials and to create the preconditions for realization on their basis of EG designs with higher (more, than by 2 times) specific electrochemical characteristics of SOFC and high-efficiency, reproducible technologies.
Research institutes, private companies, and also inpidual experts from USA, European Union, Japan and Norway are invited to participate in the project as collaborators.
The role of foreign collaborators is to provide technical advises during the project, including an exchange by accessible for collaborator information on Project theme, reviews and critical remarks to the received periodic reports. Other joint activity can include 1) visits to a place to contractors and to the plants; 2) helps in organization to accept the personnel - contractor in USA, 3) participation in conferences and workshops on themes concerning of the project.
