Christophe Coutanceau obtained his Ph.D. degree in electrochemistry in 1994 at the University of Poitiers, France. He then worked as Assistant Professor at the Laboratory of Catalysis in Organic Chemistry (LACCO) in that same institution, before being promoted in 2008. At present, he is Professor in Physical Chemistry at IC2MP and Director of the Catalysis and Unconventional Media group of the Institute of Chemistry of Poitiers. He is also chair of the Low Temperature and Fuel and Electrolysis Cells axis of the Hydrogen-Systems-Fuel Cells Research Grouping from the French National Council of Scientific Research (CNRS). For more than twenty years, his research interests include development of synthesis methods for nanostructured supported metals using green processes (microwave activation, electrochemical methods, etc.) and solvents (polyols, water) and their application as electrocatalysts in fuel cells, electrolysis cells and electrosynthesis reactors. He is also interested in the valorisation of agroresources using electrochemical methods. He has presented or published over a hundred articles in reviewed international journals, as well as several book chapters, invited lectures and world patents related to fuel cells, electrolysis cells and biomass conversion. Stève Baranton obtained his Ph.D. degree in electrochemistry in 2004. He worked conducted research in Canada and Japan before joining IC2MP as Assistant Professor. His current research interests include the development of synthesis methods for nanostructured supported metals using green processes (microwave activation, electrochemical methods, etc.) and solvents (polyols, water) and their application as electrocatalysts in fuel cells, electrolysis cells and electrosynthesis reactors. He also develops in situ spectroscopic methods. He has presented or published over 90 documents related to fuel cells, electrolysis cells and biomass conversion, including articles in reviewed international journals, book chapters, invited lectures and world patents. Thomas Audichon obtained his PhD degree in Materials and Electrochemistry in 2014 from the University of Poitiers, France. He has a post-doctoral position at the Institute of Material and Environment of Poitiers (IC2MP). His current research interests include synthesis and characterisation of nanomaterials (oxides and metals) for oxygen reduction reaction and anodic activation of water in electrolysis cells, and formulation of membrane-electrodes assemblies and measurement of electrochemical performances on an electrolysis test bench. He published several papers in international peer reviewed journals on materials for water electrolysis cells. Bruno G. Pollet is a full Professor of Renewable Energy at the Department of Energy and Process Engineering at the Norwegian University of Science and Technology (NTNU) in Trondheim. His research covers a wide range of areas in Electrochemical Engineering, Electrochemical Energy and Sono-electrochemistry (the use of Power Ultrasound in Electrochemistry) from the development of novel materials, hydrogen fuel cell to water treatment/disinfection demonstrators & prototypes. He was a Professor of Energy Materials and Systems at the University of the Western Cape (South Africa) and R&D Director of the National Hydrogen South Africa (HySA) Systems Competence Centre. He was also a co-founder and an Associate Director of the University of Birmingham Centre for Hydrogen and Fuel Cell Research in the UK. He was awarded a Diploma in Chemistry and Material Sciences from the Université Joseph Fourier (France), a BSc (Hons) in Applied Chemistry from Coventry University (UK) and an MSc in Analytical Chemistry from The University of Aberdeen (UK). He also gained his PhD in Physical Chemistry in the field of Electrochemistry and Sonochemistry at the Coventry University Sonochemistry Centre.
