The 12-month post-doctoral fellowship is open to M / F candidates motivated by the field of new technologies for energy. It is concerned by the development of electrocatalysts for the reduction of oxygen in acid medium capable of replacing the platinum of proton-exchange membrane fuel cells. The use of platinum in these systems is an obstacle to their significant long-term development. In this context, the laboratory is developing research on the implementation of CO2 laser pyrolysis of liquid precursors in order to synthesize electrocatalysts of the Metal/Carbon/Nitrogen system. The performance of synthesized materials is evaluated by electrochemical measurements according to the expertise developed in the laboratory. The aim of the project is to control the formation of very efficient catalysts with the ultimate aim of integrating them into elementary fuel cells. Tests in fuel cell configuration will be performed at CEA Grenoble.


The work consists in developing and improving the syntheses of the catalysts in collaboration with the researchers of the laboratory involved in this field. These syntheses are carried out according to two routes: a one-step route involving the implementation of the laser pyrolysis process and a two-step route consisting in synthesizing the catalysts by laser pyrolysis and then annealing under ammonia in an oven. It is on this second synthetic route that the role of the M / F post-doctoral fellow will be more focused. The final catalyst will have undergone purification steps such as washing with organic solvents and treatments in an acid medium. The M / F post-doctoral fellow will also have to participate in the characterization of the electrocatalysts synthesized for oxygen reduction. This involves the production of porous electrodes, cyclic voltammetry measurements and the determination of selectivity according to a method developed in the laboratory. Finally, the most efficient catalyst obtained will be produced at a scale of approximately 5 g in order to enable fuel cell tests.


The profile of the applicant should preferably include experience in electrochemical measurements, experience in the processing of powdered materials, and more generally in materials chemistry. Knowledge of carbon-based materials will be appreciated, as will the implementation of physical-chemical characterizations of this type of material (specific surface area measurement, Raman spectroscopy, etc.)

Work Context

The research work will be carried out at CEA Saclay as part of a project funded by CEA. A stay at CEA Grenoble at the end of the contract could be envisaged.
