Olivier JOUBERT is presently full professor in Chemistry of Materials and is Chair of the "Electrochemical storage and conversion of energy (ST2E) group at "Institut des Matériaux Jean Rouxel (CNRS-IMN)". This lab is a Joint Research Unit between CNRS (The Centre National de la Recherche Scientifique which is the French national science organization employing a scientific staff of 10 000 people) & Nantes University with approximately 200 people. CNRS-IMN is dedicated to fundamental and applied research in the fields of materials physics and solid state chemistry. The major research interests of professor JOUBERT revolve around development of new materials for technological applications such as high and intermediate temperature ceramic oxide fuel cells (SOFC and PCFC), electrolysers… 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 SOFC working under natural gas. Olivier Joubert is chairing the French Research Network on Hydrogen Energy "FRH"2 which assembles all French academic research groups in the field of production and storage of hydrogen and also fuel cell and electrolysers with about 270 permanent researchers. His group is part of FRH2 network and is involved in many national and european projects around SOFC technology.
