Olivier Joubert - Brief Overview of Current French Hydrogen Research Activities, Focus on Materials
Twenty years ago, the French scientific community working in the field of hydrogen, started to federate under the leadership of the CNRS. It took the form of successive Research Grouping (GdR) bringing together experts in solid oxide fuel cell (SOFC), proton exchange polymer membrane (PEMFC) fuel cells, hydrogen storage and systems mainly from CNRS but also from CEA. These GdRs promoted and structured an interdisciplinary field of research with excellent results.
Since January 1st of 2020, the CNRS community has formed the Research network on Hydrogen energy (FRH2) based on the active nucleus of the former GDR laboratories (29 laboratories) with about 300 researchers and professors. A new organization, "from material to system", more visible from industries has been set up around four main technical axes, the production of hydrogen, its storage, and its conversion into electricity for mobile and stationary applications and around 2 transversal axes, education and technological platforms. The first part of the presentation will give a brief overview of this french CNRS research network on hydrogen energy including some highligts for each axes.
The second part will be dedicated to the development of materials used in solid oxide fuel cells (SOFC) and more precisely to the ceramic electrolyte: optimization of the microstructure of the material via accurate monitoring of the synthesis and temperature treatment steps.
