Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Postdoc
Job title
24 Months - Postdoc in Exsolution-Based Electrode Design for High-Temperature Electrolysis
Subject
Development of new perovskite-based electrodes based on exsolution for Solid Oxide Electrolysis Cells (SOEC). The work will focus on the design, characterization, and integration of innovative materials stable in hydrogen and CO₂ atmospheres.
Contract duration (months)
24 months
Job description
This postdoc is part of the H2-EXCEL project funded under the Carnot Exploratoire program at CEA-Liten.
The objective is to design, synthesize and test new electrodes based on non-stoichiometric perovskites capable of exsolving metallic nanoparticles under reducing atmospheres. These materials are promising alternatives to Ni/YSZ electrodes, offering higher stability against coking and redox cycling, especially in co-electrolysis environments (H₂O/CO₂).
The postdoctoral researcher will lead work on:
· Designing and synthesizing perovskite-type materials (A₁₋ₓBO₃₋δ),
· Optimizing the exsolution process and catalyst structure,
· Physicochemical characterization (XRD, SEM, TEM, XPS..),
· Integration into functional SOEC electrodes (via screen-printing, tape-casting),
· Electrochemical testing under realistic conditions (multi-atmosphere test bench),
· Performance benchmarking versus state-of-the-art Ni/YSZ.
Applicant Profile
PhD in Materials Science, Solid-State Chemistry, Electrochemistry, or a related field.
Key skills :
· Materials synthesis and ceramic processing,
· Solid oxide cells or electrochemical systems,
· Physicochemical characterization techniques,
· Electrochemical impedance analysis,
· Optional: surface chemistry or catalytic materials experience.
Soft skills :
· Autonomous and structured,
· Excellent scientific communication (oral and written),
