Before joining the ICGM, Claude LAMY developed an electrocatalysis laboratory in Poitiers, whose activities focused on the oxidation of small molecules (H2, CO, HCOOH, CH3OH, C2H5OH, etc.). This research resulted in the realization and recording of cell voltage-current density curves, aimed at optimizing the specific power density (in W / cm 2) of elementary cells of hydrogen fuel cells (H 2 / O2) including proton polymer electrolyte (PEMFC), and direct oxidation of small organic molecules (DFAFC, DMFC, DEFC, etc.). They have also led to the selective electrosynthesis in an aqueous medium of organic compounds from biomass (glucose, sucrose, etc.) and to the production of hydrogen by electrolysis of water and organic components such as HCOOH, CH3OH, CH3CH2OH, etc.
I. By the way
Born in Dijon, Burgundy (France), Claude LAMY was Full Professor at the Faculty of Sciences of Poitiers, Department of Chemistry, from 1976 to 2010, where he taught physical chemistry (atomistics and molecular structures, electrochemistry, chemical kinetics, spectroscopy, electrocatalysis). He graduated from the Ecole Polytechnique (Paris 1962), graduated in Science in 1963 and holds a doctorate in 1969 from the University of Paris. After having been a researcher at the CNRS in Meudon-Bellevue (Laboratory of Interfacial Electrochemistry) from 1969 to 1976, he became Professor at the University of Poitiers in October 1976.
As former director of the Electrocatalysis Laboratory, associated with the University of Poitiers and the National Center for Scientific Research (CNRS), Claude LAMY has developed a research group specialized in Electrocatalysis. This group studied the catalytic properties of different electrode materials (monocrystalline platinum, polycrystalline platinum, dispersed platinum, platinum-based adatoms and metal alloys, transition metal macrocycles, etc.). vis-à-vis several electrochemical reactions involving small inorganic molecules involved in fuel cells (H 2, O2, CO, etc.) and organic compounds (alcohols, aldehydes, ketones, carboxylic acids, etc.). The nature, structure and composition of the electrode materials have been optimized to increase both their catalytic activity (i.e. the current density at a given potential and the specific power of the battery) and the selectivity of the reaction towards complete oxidation to CO2 or partial oxidation of a desired compound with high added value (i.e. chemical yield).
Teachings & Responsibilities
Ii. Research activities
Different technologies and applications of the first CNRS GDR on fuel cell components (PACEM and ITSOFC GDRs).
Jean-Claude GRENIER and Claude LAMY created respectively in 2001 and 2002 the first 2 CNRS Research Groups on the components of the cell core of solid oxide fuel cells (GDR ITSOFC) and membranes (GDR PACEM). The various applications envisaged (stationary electricity production, light vehicles, heavy mobility, trains, portable electronics, aerospace applications, etc.) are quasi-operational in 2022 after the massive support (9.2 billion Euros until 2030) of the government as part of the National Hydrogen Strategy. The GDR PACEM, under the responsibility of Claude Lamy, included among its first members 4 Montpellier Laboratories: LAMMI (Jacques Rozière and Deborah Jones), LCM (Bruno Ameduri), LMCCCO (Bernard Coq) and IEM (Gérald Pourcelly), the first 3 of which are now part of the ICGM.

Collaborations & Contracts
Claude LAMY has been involved in several committees of French research organizations (CNRS, ADEME, PACo Network, ANR where he was scientific manager of the "Hydrogen and Fuel Cells" programs from 2005 to 2008, etc.). and in several research contracts (EU Non-Nuclear Energy, EU Joule programmes, CNRS, PACo, EDF, GDF, PSA, etc.). He was the director of a CNRS Research Group, GDR No. 2985, "Fuel Cells All Electrolyte (PACTE)", which involved the coordination of 40 CNRS laboratories working on components (polymer electrolytes, ceramic oxides, electrocatalysts, etc.). low temperature batteries (< 90°C such as PEMFC) and high temperatures (700°C < T < 1000°C such as SOFCs), with three CEA laboratories and four industry laboratories (EDF, GDF-Suez, Saint-Gobain, Areva).
