• Director of the French Research Network on Hydrogen (FRH2) from CNRS
• Chair of ST2E group of “Institut des Matériaux de Nantes Jean Rouxel” (IMN).
• Scopus ID: 7007036225

Expertise:

• High temperature Fuel Cells (SOFC) and electrolysers (SOEC)
• Solid state and materials chemistry
• Synthesis (Solid state and combustion methods) and characterization of ceramic materials (X-ray diffraction, Electrochemical Impedance Spectroscopy, Thermal analysis…)
• Fuel cell performance testing

Major research interests:

His main research interests are in the development of new oxide materials for technological applications, including High Temperature fuel cells (SOFC and PCFC). Particular focus in recent years has been the development of new electrolyte for solid oxide fuel cell materials, with very promising results being observed for brownmillerite-type oxide ion and proton conductors. In addition to this work in this area, his group also has ongoing research in the development of anode and cathode and the realization and testing of complete cellsProjets de recherche en cours

Biography:

Olivier Joubert (1965) is presently full professor in Chemistry of Materials at University of Nantes and is Chair of electrochemical storage and conversion of energy group (ST2E) of “Institut des Matériaux Jean Rouxel (CNRS-IMN)” and Member of the Board of Directors of the International Association for Hydrogen Energy (IAHE). IMN lab is a Joint Research Unit between CNRS & Nantes University with approximately 150 people. The major research interests of professor Joubert revolve around development of new materials for technological applications such as high and intermediate temperature ceramic Solid Oxide (SO) fuel or electrolyser cells (SOFC and SOEC). He is a solid state chemist and his research activities involve development of new oxide materials like, novel perovskite-type ion and proton conductors and anode for SO Cells. He is co-author of 140 publications, 67 invited talks and 5 patents.

Olivier Joubert is chairing the French Research Network on Hydrogen Energy (FRH2 with about 300 permanent researchers) which assembles all French academic research groups in the field of electrolysis production and storage of hydrogen and also its conversion to electricity using fuel cell. His group is part of FRH2 network and is involved in many national and european projects around SOFC technology. He is also the main organizer of the International Discussion on Hydrogen Energy and Applications (IDHEA) held in Nantes in 2014 and 2016.

Between 2014 and 2020, O. Joubert was also in charge of the expertise cell ERIMAT in Capacités SAS, a private subsidiary of the University of Nantes dedicated to the development of research, and provides assessment, advice to industries.

Publications:
