Offer Description Hydrogen is nowadays considered an interesting energy vector that could be used in a climate neutral society when combined with an efficient electrochemical system able to produce electricity in fuel cell mode during peaks of consumption and hydrogen in electrolysis mode during low demand periods. In this context, the high-temperature electrochemical SOC devices (650-850 °C) are considered one of the most promising technologies thanks to various advantages such as high efficiency, relative low cost, and good reversibility in fuel cell (SOFC) and electrolysis (SOEC) operating modes.
The post-doctoral work represents the main part of the PTC-MP-INTERMEDE project, which has been initiated to study interactions between interconnect, coating, and electrochemical cell of small size depending on the operating mode and for long durations (> 3000 h). This project exclusively funds the post-doctoral work.
Post-doctoral missions will include:
Adaptation of an electrochemical test bench dedicated to the specific study of interactions between interconnect, coating, and SOFC/SOEC cell.
Management of associated tests without and with coatings selected in collaboration with S2CM/LECNA.
Fulfilment and analysis of relevant electrochemical measurements during testing (polarization curves, electrochemical impedance spectroscopy, durability curves).
Post-test characterizations of the different oxide layers formed on the interconnect surface and the chromium poisoning of the cell electrodes.
Long-term oxidation and chromium evaporation tests on steel samples at STH2.
In collaboration with technicians of the team, the post-doctoral fellow will define and plan the testing program, from test mounting to analysis of obtained results. Proactivity and reliance on CEA expertise about SOEC in terms of electrolyte and electrodes materials, corrosion of metals, and electrochemical characterizations are expected.
This work should lead to at least 1 publication and 1 presentation at the EFCF conference in 2026.
Minimum Requirements PhD in electrochemistry and/or high temperature corrosion fields.
Knowledge and Skills Required: Good academic knowledge in electrochemistry and/or high temperature corrosion.
Expertise in electrochemical measurements.
Ability to lead a research program.
Great liking for experimental work.
Ability to ensure dissemination activities (written and oral communication, publications).
Ability to work in a team.
Autonomy, enthusiasm, energy, kindliness, and scientific rigour/precision.
The supply of recommendation letters will be appreciated.
