High-temperature electrochemical SOC devices (650-850 °C) are considered as one of the most promising technologies thanks to a high efficiency, a relative low cost and a good reversibility in fuel cell (SOFC) and electrolysis (SOEC) operating modes. If the SOC technology achieves satisfying performances nowadays, SOCs durability needs to be further improved to reach a degradation rate lower than 1%/kh for a life span of about 50 kh and its industrial deployment. Then to better understand and limit metallic interconnect oxidation and chromium evaporation through the use of coatings remains a key challenge.

Simultaneously to classical studies on kinetics of interconnect oxidation, chromium evaporation and area specific resistance in relevant operating conditions, the interaction between interconnect, coating and electrochemical cell of small size depending on the operating mode and for long durations (> 3000 h) will represent the core of your postdoctoral work.

You will evaluate protective coatings and a contact layer thanks to electrochemical characterizations of performances and durability of the adjacent cell, and post-test microstructural characterizations as well compared to the bare steel.

· Adaptation of an electrochemical test bench dedicated to this specific study of interactions between interconnect, coating and SOFC/SOEC cell,

· Management of the associated tests (performing and analysis of electrochemical measurements),

· Post-test characterizations of the different oxide layers formed on the interconnect surface and the chromium poisoning of the cell electrodes,
