Sensors, SOFC stacks, and instrumentation

Research activities focus on the electrical properties of solids interacting with gases, and are applied to the development of gas and particle sensors, as well as Solid Oxide Fuel Cells (SOFC).

They cover the entire value chain, from the physicochemical principles of gas-solid interactions and their modeling, to the development of chemical sensors based on semiconductor or ionic conductor materials via various shaping technologies (screen printing, inkjet, etc.), the implementation and performance evaluation of sensors on laboratory or on-site test benches, and data processing.
