General information

Name of the project: New materials and technologies of solid state fuel cells, ceramic membranes, and high temperature gas electrolysers

Strategy for Scientific and Technological Development Priority Level: б


Goals and objectives

Research directions: New oxide and composite materials, technologies of new electrochemical devices of application in the power industry, fundamental research in the domain of high temperature electrochemistry and solid state physical chemistry

Project objective: Development of new materials with high mixed ion-electron conductivity and other functional qualities necessary for usage as electrodes of medium temperature solid oxide fuel cells, solid oxide electrolysers and ceramic membranes, as well as state-of-the-art technologies for producing highly efficient electrochemical devices adaptable to manufacturing conditions of industrial partners


The practical value of the study

  • New materials have been developed for solid oxide fuel cell (SOFC), gas electrolysers (SOE) and ceramic membranes with enhanced stability and functional characteristics ensuring high efficiency.
  • New scientific and technological approaches have been developed for producing SOFC/SOE electrodes and ceramic membranes.
  • Our researchers have optimized approaches to production and modes of operation of electrochemical devices that ensure adaptation to various technological tasks and achievement of target operational lifetime.
  • A wide range of fundamental data has been collected concerning phase ratios, mechanisms of formation and transfer of defects, electrochemical activity, parameters of electron and ion transfer, chemical and thermal expansion, kinetic and morphological stability and other functional properties of new materials.

Implemented results of research:

  • We have completed a number of agreements and contracts with industrial and technological partners in the field of SOFCs. Technological documentations has been compiled for practical applications of results of the project transferred to our partners.
  • The Laboratory has conducted operational life testing of new materials, components, SOFCs and model electrochemical devices.
  • Scientific results of the project are currently used for optimization of batteries of SOFCs with planar design for stationary and mobile applications, in particular, for developing urban municipal electric vehicles with extended range.

Education and career development:

  • We have trained 10 young scientists and students who have started their research in the domain of the project.
  • 2 doctoral dissertations and 6 candidate dissertations have been defended.
  • Additional training has been organized for more than 40 young employees of scientific organizations who participated in three Schools for young scientists.
  • We have organized internships for young researchers from the Tomsk Polytechnic University, the Novosibirsk State University, and the Institute of Solid State Chemistry and Mechanochemistry of the Siberian Department of the Russian Academy of Sciences. The internships were aimed at training in operation modern equipment and research methodologies in the domain of the project.
  • More than 40 presentations at international and all-Russian scientific conferences by young researchers and students.

Organizational and structural changes: The Laboratory is used within the Distributed Collective Utilization Center of the Institute of Solid State Physics of the Russian Academy of Sciences.

Other results:

  • 7 intellectual property objects produced
  • More than 15 grants received.
  • Members of the academic staff of the Laboratory conduct annual all-Russian conferences with international participants «Fuel cells and electric devices based on them» and the School for young scientists «Modern aspects of highly efficient fuel cells and electric devices based on them».
